Essay: On The Nature of Intelligence

By Robert DePaolo

This article discusses the neuropsychological and operational factors that go into defining the nature of intelligence with reference to academic performance, intelligence tests and social-emotional functioning.

Classical Definitions…

A number of definitions have been employed to describe the nature of intelligence. Binet felt the essential component was judgment, that other faculties were less relevant (Bergin & Cizek 2001). Wechsler defined it as a global capacity to act purposefully, to think rationally and to adapt to his environment (1958). Cyril Burt offered a rather concise definition, to wit: Innate general cognitive ability (Jensen, 1972).

More recent definitions have come from the field of neuroscience but with not much more specificity. For example in using MRI studies, Haier (2007) found a modest correlation between glucose metabolism in the brain and scores on IQ tests. McDaniel found a correlation of .40 between brain size and IQ test scores and Rushton’s research yielded similar results (2009). The problem with studies like these is that they view IQ as an independent variable and provide no insight into the nature of Intelligence.

While meaningful, these studies and descriptions are also broad and tautological, which is perhaps why one of the fail safe definitions familiar to most psychology graduate students is that intelligence is best defined as what is measured on intelligence tests.

It is probably a good idea to pivot off that sarcastic characterization in broaching this issue because so many skills, faculties, behaviors and feelings have been encompassed in the word intelligence that it is conceivable there is no such single entity; that perhaps intelligence is merely another anthropocentric manifestation of the human need to label experience.

Yet the question is important, and for several reasons. First we use intelligence as measurement for so many social, educational and vocational purposes that to dismiss it as too vague leaves out a lot of life and experience. Also, there are clinical aspects to intelligence that are important to consider; for example as a means of determining baseline levels, pre and post morbid capacities in the aftermath of organic brain damage or psychosis.

Beyond that are deeper implications, especially in light of what Darwin called sexual selection. This is a process whereby females select males based on species-specific traits deemed favorable to survival. It is no secret that human females place high value intelligence in males, whose cognitive assets would not only make them desirable mates but also make them better providers, parents, etc. In that sense intelligence would have to be socially, sexually, economically, culturally and experientially important. But then what is it?

Instruments and Rationales…

The Wechsler intelligence instruments are probably the most widely used in clinical, school and vocational settings. It is not just due to their pristine standardization formats, their performance-predictive value or their statistical correlation with other tests. The construct of these instruments is also an important reason for their popularity. With verbal comprehension, perceptual reasoning, processing speed and working memory sections, these tests would seem to tap into a variety of brain sites and functions, as well as into the mind’s capacity to integrate those functions as a measure of inter-cephalic accessibility.

In an indirect way, the Wechsler tests ask questions such as; can the visual processing occiput of the brain perceive details and utilize figure-ground perceptual skills to identify visual components based on associative relevance? Moreover, can the occiput interact with the parietal strip in the processing speed section of the Wechsler instrument so that the eyes, hands and visual memory can co-function toward a singular goal? These tests also ask whether rote memory can be separated from operational memory, where numbers and letters have to be re-organized in mind as well as be repeated from a simple, sequential recitation of digits.

While the Wechsler instruments contain four functional categories, they arguably entail neurological functions beyond the rubric of verbal comprehension, perceptual reasoning, processing speed or working memory. In fact there are neural underpinnings to each of these functions which can enable one to dig deeper into the nature of intelligence.

Complexity begets simplicity…

We can begin discussion of brain-and-intelligence by referring to information dynamics because beyond all else the brain is an information-processing system. Information has specific parameters; one of which is that it can only exist as material extracted from a prior state of uncertainty. That means intelligence must be some function of a capacity to sift through neuronal networks efficiently enough to find information pertinent to the task at hand – be it academic, social, emotional, mechanical, auditory, visual, proprioceptive, motoric or combinations of those. Thus one component of intelligence is a streamlining neural search capacity enabling the person to extract information from noise. For the sake of convenience we can call that the sifting function.

But there is more to it than that. The neurology of the noise-laden human brain, with its 86 billion neurons, places limits on searching and sifting. Each foray into neural information extraction is accompanied by an enhancement of neural activation (Lashley 1950) (Kak, 1996). Therefore one must not only be able to search and sift but do so before arousal levels reach an aversive threshold. In that context we can posit that another component of intelligence is arousal tolerance. It is perhaps akin to what Eysenck referred to as tough mindedness.

But even that won’t suffice. No one is capable of tolerating brain arousal for an extended period of time and in that sense two other factors come into play. One is rapidity – the capacity to “beat the arousal clock” so that information extraction can occur before an aversive state is reached. We can call that the rapid processing factor.

With that we come to the next requisite component. With so many neurons and inter-axial, dendritic connections one can only process so rapidly. It isn’t just speed of processing that does the trick but a capacity to streamline the search, that is, to narrow it down so that extraction is made more convenient. That is done in several ways. One of which is by having what Piaget called effective schemata. These are expectations of what an answer or response should look like, i.e. an a priori mechanism for judging relevance so pathways can proceed from global to narrow (task-specific) activation.

Streamlining can occur in several ways. One is through neural synchrony; which is a rhythmic coordination between excitatory and inhibitory neuronal activity in the brain that can override randomness by a well-coordinated, regulatory tempo. That in turn requires that brain waves be relatively free of spike activity, with smooth check and balance interaction among brain sites to create the optimal learning wave activity – which is in most instances is high frequency, low amplitude activity typified by beta waves.

Most learners are not aware of being able to summon beta wave activity at will, and with certain cognitive assets do not have to be, particularly if they can streamline the search through use of a cataloguing mechanism. This component is analogous to the card catalogue system in a library which preclude our having to search for books at random. it is called categorical language.

Mass Encoding in the Brain…

Once upon a time language was presumed to reside in frontal-parietal sections of the human brain, in areas known as the Broca and Wernicke lobes. More recent research has shown that human language deriving circuits are actually spread widely throughout the brain (Binder, Frost et. al 1997). Such linguistic dispersion is a tip-off to its most essential function.

While language certainly enhances social communication, cultural advancement and any number of other aspects of life, its main purpose might be to guide and streamline the inter-cerebral search for information so as to prevent hyper arousal, categorize memory and place a secondary code on experience so that memory can itself be spread around the brain (Luria 1973) (Windolz 1990).

If language is a beacon of light cutting through the fog of neuronal complexity, then one obvious criteria in defining intelligence would be a linguistic categorical capacity. Note that this is different from language per se, i.e. its idioms, inferences, tonality etc. It is a labeling mechanism. For example, saying my cat is cute and cuddly is an example of language but it is not necessarily categorical. Lots of things are cute and cuddly. On the other hand saying, my cat is a mammal and member of the genus Felidae with a flexible backbone enabling it to leap from heights without hurting itself is highly categorical.

In that context, one could ask why categorical language is so important in the retrieval/arousal modulating process. One reason is that every label provides two bits of information that corresponds to the excitatory/inhibitory process. A label tells us what something is, and by extrapolation what it is not. In other words labeling a cat in a specific way, excludes it from being some other creature. In that sense every categorical language bit enhances the efficiency of the brain’s rhythm via orchestration of excitation and inhibition. The fact that language phenomena are dispersed throughout the brain speeds up the information retrieval process.

Internal Speech…

When one discusses language the usual reference is to overt language, that is, the spoken word in all its manifestations. Yet as Luria pointed out language development is more complex than that (1973). Speech is like reading, it begins with overt expression then in the course of development gets whittled down into fractionated, silent language via the inhibitory incorporation of language pathways in the prefrontal lobes. Through that developmental process we become capable of talking to ourselves in sub-audible ways.

The notion of self-talk regulation is as old as history itself. It was discussed by the Roman emperor and philosopher Marcus Aurelius and in modern times has been incorporated into the various rational and cognitive-behavior therapy formats.

Internal speech is a bugaboo in the field of education, with regard to assessing not only intelligence but also academic performance and emotional behavior patterns. Modern educators refer to a similar process as metacognition, and insist it is a necessary skill in thinking, writing, reading and performing in general. Clinicians in the field of psychology view it as essential in the development of self-control and conscience. Yet it is basically immeasurable. There are no tests that issue standard scores on internal speech capacities, therefore no way to gauge anyone’s capacity to guide themselves through intellectual tasks or emotional turmoil. There are a few tests and tools to assess metacognition, for example the Multiple Intelligences Test and Index of Learning Styles Questionnaire, but these instruments address overt behavior and language – as all tests must, and, except by inference cannot get inside the brain to evaluate moment to moment internal commentary. That critical component of intelligence is unfortunately hidden within the recesses of mind. Yet it is part of what makes up intelligence and is therefore included in this analysis.
Thus far, the criteria for defining collectively the nature of intelligence have been described as…

Noise-breaking (efficient uncertainty reduction) in the brain, i.e. the sifting function

Arousal tolerance during retrieval

Speed of information processing in ameliorating duration and level of arousal

Neuronal rhythmic efficiency as a means by which to speed up response time via excitation/inhibition co-activity within brain pathways.

Categorical language as a pan-cephalic mechanism serving to narrow down information search and retrieval.

Internalization of categorical language to enhance cognition, motivation and streamline task focus.

Faculties and Integration…

The above factors provide a rough outline of how intellectual ability is defined and executed. They do not address the specific systems of the brain and how they interact. It is of important to factor in those elements but customary descriptions of how these faculties parlay into a concept of intelligence are in some instances vague and problematic.

Obviously for intelligence to be manifest requires adequate capacity for sensation. For the sake of convenience specific sensory functions will be put aside, in favor of a discussion of how sensory, motor and other faculties operate integratively.

Whether in terms of specific test procedures like the Wechsler, or in every day examples of intelligence, most if not all cognitive behavior involves a meshing of sensory systems. Reading a newspaper involves the visual centers of the occiput, language processing circuits within the brain, and perhaps, depending on the nature of the article, even the emotion-registering centers within the limbic brain. Thus a facile interaction among these brain sites would seem to be prerequisite to any use of functional intelligence.

The question arises as to how integration is facilitated, and more specifically, how brain function would affect the expression of intelligence. In some sense the answer is quite simple and can be formulated in two ways. First, since these various sensory locales provide separate functions, and in many instances feature different neuronal structures, integrating them would appear to be a difficult task. Disparate pathways would have to be traversed in order to conceptualize experience. Certainly language provides a bridge across sensory systems. For example the phrase… the local football team, the ol’ red and blue is red hot after running over opponents in their first five games… is a sentence with tactile, visual and motor components brought together by language codes. But beyond language synthesis, other factors must come into play. Neural connectivity must be efficient and flexible enough to not only build bridges but do so quickly enough to prevent aversive states of arousal from overriding the need to know.

One way for that to occur is to have parts of the brain that are not in themselves concerned with specific functions, therefore neuronally malleable. These non-specific circuits would be able to scan the brain, adapt to inputs and in effect serve as regulatory, monitoring mechanisms in the integration of experience.

Anatomically there are such structures. One lies in the prefrontal lobe of the cortex. The other lies in the cerebellum, which is situated in the back of the brain. The fact that these two circuits have the greatest number of connective neural branches with other parts of the brain suggests they are oversight circuits.

Indeed the prefrontal cortex and cerebellum have been described as regulatory computers in the brain because of this structural and functional oversight capacity (Miller, Cummings 2007 ),(Herculano- Houzel, 2010), Timman (2007). Each operates in a different manner, however and that has implications for how they affect the expression of intelligence. The prefrontal lobe is an extension of the fronto-parietal lobes which have language functions. As one travels across the brain from the parietal to the prefrontal lobe there is a shift from overt language functions to more covert, self- directed language functions. In effect the prefrontal lobe enables the person to talk to himself – which provides self-regulation, subcomponents of which include moral regulation, social empathy and the aforementioned metacognition.

Meanwhile, the cerebellum provides a broad balancing function, so that other systems can operate automatically. It not only allows the person to take movement for granted – for example being able to, in the famous phrase…walk and chew gum at the same time. It also does the same for cognitive functions. For instance it enables one to concentrate through background noise, maintain fine motor stability so that a student can both anchor his left arm down on a desk and write a composition for English literature class with his right. Due to the provision of pan-stability the cerebellum facilitates sensory integration as well. Thus while the frontal lobes provide categorical and self-directive motives and information search streamlining, the cerebellum eliminates extraneous inputs and puts peripheral functions on hold by rendering them automatic and therefore less intrusive with respect to the conscious execution of specific tasks.

Ordinarily these two functions are referred to as executive functioning and automaticity. Since integration is so central to intellectual functioning and since they facilitate that process, those two components would seem to warrant inclusion into a conceptual definition of intelligence.

The Testing Zeitgeist…

At present many of these functions are measured by separate tests; for example the BRIEF instrument is used to gauge executive functional capacities. Various occupational therapy tests are used to measure motor balance. The WISC-IV integrative instrument assesses integration of various skills indigenous to the Wechsler procotol. One has to wonder if at some point a test of intelligence (as defined here, however speculatively) might be developed to encompass all the skills discussed above. Such an instrument would enable clinicians and educators to have, at long last, an instrument by which to co-evaluate intelligence and brain function. Doing so might involve amalgamation of current test formats, for example the BRIEF, Wechsler, Multiple Intelligences Test and other instruments. Or perhaps new test items could be developed to measure these skills through a test format brief enough to sustain but not overtax the client or student’s investment, lengthy enough to have face and construct validity and definitive enough to determining with precision both the nature of intelligence and the intellectual capacities of any given subject.

Essay: Physics, Nature and Mind

By Robert DePaolo

Abstract

This article presents ideas on the integration of theoretical physics, brain function and morality under the rubric of Information Theory. The factors of uncertainty, ultra-stability and systemic complexity are discussed in terms of how systems develop permanence and what mechanisms underlying human cognition and moral thinking might have in common with the laws of physics. The point is made that the increasing mass and complexity of brains produced a complementary chaos-to-order transition that is also responsible for the quantum-induced order observed in nature.

Organization/Information…

In discussing any information system it is necessary to begin with an apparent paradox: the notion that due to the laws of entropy, order cannot be either a permanent condition or a true point of origin. It must either emanate, i.e. evolve, from something else or undergo fluctuations whereby it represents a transition point on the uncertainty-to–organizational continuum. (Shannon & Weaver 1949), (Berger, Calabrese, 1975) In other words, like every system in nature it is not static but rather dynamic.

Such a process is an essential component of Information Theory; one tenet of which holds that information can only be gleaned from a prior state of uncertainty. The idea that uncertainty (confusion) is a necessary prelude to organization (whether in the domain of particle physics or human cognition) it is a pervasive, credible idea. It is seen in Piaget’s writings on human cognitive and moral development – wherein a state of disequilibrium is deemed a prerequisite to intellectual growth. (Piaget & Inhelder, 1969). It is also seen in Freud’s theory of creativity, which he presumed is fostered by a state of uncertainty he referred to as anxiety. Beyond the human realm it is of course seen in Heisenberg’s principle of uncertainty (1930) and de Broglie’s notions of the wave-particle duality and quantum fluctuations (1960) that seem at odds with Einstein’s equally valid (classical) theory of an orderly universe.

Theoretical physicists have grappled with the apparent contradiction between classical and quantum physics for some time, under the assumption that uncertainty and order seem to be at odds with one another. The question of how the cosmos can at once be lawful (at the macro-physical level) yet chaotic (in the particle domain) has been something of a mystery for decades. It need not be; particularly uses information dynamics as a bridge-building concept. In that context one merely needs to accept that order is not a natural state. Neither is chaos. Rather they are interdependent and complementary. One cannot exist without the other. Therefore one can begin with the premise that, as Bronowksi suggested, laws are as much a function of mind as of a true reality; an internal representation rather than an isomorphic reflection of nature than of true reality (1973).

Distinctions and Causations…

The assumption that chaos and order are complementary would seem to require some sort of operational description. How and/or why are the two states interdependent? The simple answer is that since all systems tend to run down, it stands to reason that since there are only two possibilities in the natural world that as one declines the other would emerge. There are of course varying degrees of uncertainty and order but it can be inferred that, all things being equal, a transition out of one state leads to the emergence of the other. Yet while that addresses the question of “what” it does not consider the how and why of the process. To address those questions one can begin by discussing how chaos evolves into order.

As a first explanatory step, the reader is asked to imagine what a state of absolute uncertainty would be like. In effect it would be one of complete monotony, in which there were no individualized features – nothing to stand out from the crowd – so to speak. The so-called cosmic egg, which was composed of plasma, would be one example of a nearly complete state of entropy or uncertainty. Being in such a state would by definition render it completely devoid of information content because information always involves a distinction between or among signals. Just as language grammar entails different sounds, semantic distinctions, parts of speech, definitions etc. (lest it be incomprehensible) so too does any information system.

Thus information begins with some sort of break from monotony or “noise.”
The reason why is a function of two things. First, because the “info-plasma”is not yet systemic, it has no implicit order and will, as a result of quantum principles, tend toward constant flux. That would render it highly volatile.

The second reason is that due to that flux there will always be some probability that a set of distinctions will emerge from within the plasmodic state. When the cosmos began, one such distinction was the formation of matter – which ostensibly became possible when the temperature cooled enough to enable particle formation and gravitational clustering. With that came a subsequent cascade of distinctions, including separate of elements, differing masses, forces and the like. Such an info-evolutionary process led to the creation and stabilization of the universe as we know it.

As distinctive clusters increased so did the information content of the universe, but the process did not end there. The flip side of the noise-to-information ( or flux to order) relationship, is that distinctions themselves tend to run down to a state of entropy, in the process devolving into mere noise and ultra-uniformity. That is because being separate they are less-influenced by outside sources. Therefore, lacking any sort of hybrid/complexity safety net, they will tend toward sameness and uncertainty – and so the cycle continues.

Yet clearly some systems have prevailed, most notably the universe and on a smaller scale, memories in the brain. With regard to the latter, one could ask why memories don’t run down as a result of entropy.

One possible answer can be found in the idea of complexity. As W.R. Ashby proposed, any system with enough complexity to encompass both stability and flux (i.e. develop ultra-stable parameters) can incorporate within its boundaries both chaos and order (Conant, 1981). That would enable it to endure over time. In effect complexity enables the system to change without changing, which provides a degree of insulation against systemic deterioration.

The Metaphysical Universe…

When physicist inquire as to what makes order, for example why there are only so many elements, forces, charges and the confusing co-existence of matter, anti-matter, symmetry and flux many have ended up with quasi-spiritual explanations. (It isn’t just Einstein who postulated that God was somehow involved in the structure of space, time and matter). While at face value, physics and faith seem mutually exclusive it is conceivable that a god-figure, say in the form of an immutable, governing process is responsible for the organization of the universe. If so, then without refuting either religion or science one can discuss the details of how this process might operate.

Absorption/Separation…

That raise the question of how can one characterize this God-process in a way that satisfies both physics and metaphysics? In addressing that question, consider the following.

Suppose a common feature of all things underlying cognition, memory, morality and cosmological constancy lies can be described as a duality consisting of absorption and separation. More specifically In effect, any system with distinct elements that is capable of absorbing new elements can resist entropy and consequently will have a capacity to grow, evolve, learn, adapt and endure.

Application…

With regard to the universe, this would signify a complex system in which flux prevailed at the particle level, while constancy prevailed at the classical level – comprising all one ultra-stable system rather than two separate worlds. With respect to human functions like memory, moral thinking, learning, social relationships it would mean having the anatomical and psychological capability to both change and maintain of an overall identity or set of values without unraveling the overall system.

This idea is speculative but has interesting implications for human brain function. It is apparent that the brain operates through a flux to order, general to specific neural activation mechanism (Kak 1996). In addition to Kak’s work, Lashley’s notion of mass activation and equi-potentiality comprises another example of how mental activity unfolds (1950). Indeed the very structure of brain cells, which proceed from soma to multiple branches and back again, suggests information transmission in the brain proceeds from the general to the specific. In that sense human cognition would seem to involve an uncertainty-reducing process. By that line of reasoning terms such as intelligence, emotion, memory and cognition might be convenient but less than accurate descriptions of what is most fundamentally an information retrieval process. All of our mental activities, from artistic expression to literary endeavors, to picking out a pair of shoes in a department store to finding just the right words to say in some social context, simply reenacting the same process that gave rise to the origin and maintenance of the universe.

Encoding the Haystack…

Speaking of word finding, it is conceivable that the advent of language, while adaptive for a wide variety of reasons, was most essentially an adaptation to increased uncertainty within the expansive human brain. Having 86 billion neurons and vastly more inter-neural connections creates the potential for a lot of uncertainty. Perhaps one reason insanity is such a human problem is due to the high potential for such chaos. One way nature could have modulated human brain expansion would have been to provide neuronal configurations by which to codify experience (both from the outside world and within internal brain impulses). Such a linguistic, noise-busting mechanism, would have been essential in warding off insanity, confusion and other states of internal chaos.

One fortuitous byproduct of that would have been a new and enhanced capacity to integrate new and old ideas, familiar and novel perceptions, sounds and memories to produce broader, systemic representations of the natural world and of human experience – something we now call art. It might also have given rise to human morality, which includes themes of distinction-absorption. For example, with regard to distinctions: having an individual identity facilitates goal setting, which to leads to achievement. On the other hand with regard to absorption, having a capacity to extend experience in incorporating the feelings of others leads to empathy, compassion and a capacity to blend ideas and customs from other peoples and cultures – as the Romans did with religion, art, architecture and law in creating a template for subsequent societies.

One can even apply this model to the most basic component of life – the cell. It too has a distinction/absorption capability. It can sustain itself individually via the insulation of nuclei and mitochondria within its inner enclaves yet extend beyond itself and assimilate new inputs through a semi-permeable membrane enabling an exchange of nutrients, chemicals, light and waste materials.

Whether it is described as chaos to order, uncertainty-to information, or distinction-to–absorption, this information model might well be a core feature of our world, governing, or at least making possible, all we are, all we do and all we see around us. It could not be defined as god in the traditional sense, e.g. as a figure with specific physical traits, voice or and temperament but it could be defined in a way similar to Aristotle’s concept of a true, pervasive cosmic anchor point which he called the “unmoved mover.”

REFERENCES

Aristotle Notes: In Book 8 of Physics, and Book 12 of Metaphysics Aristotle expressed a belief in an unchanging entity responsible for creating the order in nature. He was no other possibility than to conceive of a point of stability as being primal and capable of regulatory functions, i.e. not mired down in its own complexity yet omni-influential.

A DISCUSSION OF READING DISORDERS: Cognitive, Perceptual and Mnemonic Elements

September 18th, 2014 by Robert DePaolo | Posted in Psychology | No Comments » | 37 views | Print this Article

By Robert DePaolo

Abstract

This article discusses the interplay of perceptual, memory and cognitive skills in learning how to read and extrapolates from that as to possible causes and remedial strategies involved in the diagnosis and remediation of reading disorders.

A Perplexing Problem…

In some ways the very idea of a reading disorder makes little sense; particularly in light of the “all things being equal” paradigm – i.e. that reading teachers and curriculum materials are usually adequate vehicles by which to impart this skill. To some extent, this is also true with regard to neuro-developmental factors.

For example, assume a given child has average intelligence, which, according to a study conducted by the Council of Exceptional Children (2011) is typical of most students with reading disorders. The fact that intellectual tests measure many of the same skills needed to learn to read, i.e. auditory memory, visual perception, visual computation and spatial perception suggests the reading disabled child’s cognitive and perceptual faculties are functioning well enough to absorb a wide variety of inputs from various sources (school, family, the general environment). This is especially relevant in light of the fact that the evidence for a specific, neurological dysfunction is varied and questionable. For example while some MRI studies have pointed to prefrontal cortical and executive function deficiencies (Beneventi, Tonessen et al. 2010) other studies have suggested cerebellar dysfunction (Nicolson, Faucett et. al 2001) while still another implicated working memory – presumably arising from temporal left hemispheric roots (Berninger, Raskind, 2008). These assumptions are mostly based on brain activity levels – as derived from MRI studies and do not point to pathologies per se. In fact Berninger cautioned against drawing conclusions of neuro-pathological roots to reading disorders due to the fact that unusual brain activity patterns can arise from behavioral compensations learned by the child, resulting in skewed shifts in brain blood flow rather than from neuropathy. The idea that various brain sites could be involved in producing the disorder – as it often asserted with regard to more severe learning disorders such as autism, seems somewhat specious. Children with reading disorders are usually normal in every respect, which runs contrary to the global brain dysfunction hypothesis inferable from these various research and theoretical sources.

In that context, assume the child has normal vision, hearing and language-associative capacities. That combination of skills should enable the child to develop the visual associative capacities needed to learn letters and words, the auditory/phonetic capacities to understand sound-symbol relationships and the linguistic ability to interpret reading passages within a communicative/grammatical framework.

The fact that children with reading disorders don’t typically exhibit significant cognitive deficits (i.e. fall generally within or even above average range) does not mean all children fitting in this category will have the same level of reading proficiency. Indeed many of the cognitive and academic tests used to assess intelligence and achievement (for example the Wechsler Intellectual (WISC) and Wechsler Academic scales (WIAT) feature performance correlations as part of the measurement process. For instance a student with a full scale WISC score of 88, will not be expected to read as well as a student with a score of 115. As an aside, one of the ostensible problems with public education in the U.S. derives from the super-egalitarian cultural premise incorporated implicitly into the public education system; that if a child tries hard enough he or she can achieve anything they want. Real life, case studies and data suggest that might be a bit fanciful, and perhaps as corollary, that one-size-fits-all models, as seen in the No Child Left Behind evaluation process and the Common Core curriculum might not be terribly realistic – some discussion of that later.

On the other hand many students with strong, above average cognitive ability have a reading disorder. While some sort of soft neuro-dysfunction might be involved, the learning aspects of a reading disorder will the primary foci of this essay.

The Reading Gestalt…

An interesting parallel can be drawn between how an aspiring little leaguer learns to pitch a baseball and how he learns to read. At the risk of appearing antediluvian, this writer recalls, as a nine year old pitcher in little league a coach’s advice on the mechanics of pitching a baseball. While a certain amount of grumpiness and protest ensued (from both sides) the lesson boiled down to a single principle… make sure your wind-up, leg kick and delivery are all in one motion. Translated, the message was; don’t breakdown the movements. Instead learn to blend them together into one continuous (holistic) movement pattern.

In these words the coach was referencing unwittingly what psychologists call a “gestalt,” which means a melding of parts into a fluid whole. By his reckoning, a competent pitcher. even at little league level, would be able to take for granted – indeed virtually disregard – the nuts and bolts of the specific sequences involved in tossing the ball toward home plate in favor of a holistic, “windup.” Once the muscles and mind were trained that way, the kid can focus on strikes and balls.

Reading involves a similar gestalt process. It isn’t long after immersion that the young reader’s focus veers toward meaning (in line with his natural sense of language) and away from individual phonic, grammatical components. Most reading teachers understand that and come to expect fluency to kick in once the child acquires the fundamentals of letter, word and sound associations. Some also probably understand that teaching these fundamentals can also have a paradoxical effect on the learning process.

Why such an odd assertion? Because the early teaching methods are (not to the fault of the teacher) artificial, while the actual backdrop of reading (the language-based aspect) is natural – even ostensibly genetic.

Reading is obviously a language–related skill. Under normal circumstances language learning comes naturally to a child. As Lenneberg (1967) argued, a child does not have to be taught how to speak. Certainly he or she profits from social interaction, modeling and exposure to language idioms within the environment. However the child needn’t be taught to say his first words and the virtual explosion of vocabulary in the first several years of development appears not to be a direct function of teaching (Chomsky 2012).

Conversely, the child has no inherent predisposition toward an understanding of letters, words or numbers; a fact substantiated by human evolution. While mankind has been talking for perhaps 100,000 years, letters were only invented around 10,000 years ago and when early humans did begin to symbolize their world some 30,000 years ago it was in the form of concrete pictorials rather than abstract symbols. That historical fact makes the brain dysfunction thesis seem a bit specious – it would be akin to surmising that having difficulty fixing a washing machine was the result of deficient blood flow in the prefrontal cortex.

Because reading requires the integration (and restructuring) of a natural skill with a man-made skill, the child is forced to step back and symbolize what he already knows how to do. It is analogous to teaching him to crawl after he has taken his first steps.

Reading is a Conversation…

In some sense, reading is nothing more than a symbolic representation of talking and listening. However reading is obviously a more complex version of language. For example speech per se does not involve visuals. Nor does it require a cognitive pause-function, forcing the linguistic thought process to slow down in deference to the visual and grammatical regulation inherent in a reading exercise.

A child may refer to visual stimuli before speaking; for example seeing or pointing to an object and commenting… “horsie”…”dada” etc. But he does not have to hold back once expression begins in deference to grammatical rules and visual/symbolic differentiations.

Reading, Attention and Integration…

With reference to the above comments, it is possible to assume a reading disorder might be partially related to a difficulty melding fluidly the rapid speed, cadence and flow of natural language with the cognitive, perceptual and mnemonic inhibition involved in learning to read.

Does that imply that a reading disorder is actually an attention-related problem? In some cases that is probably true. For example research conducted at the Mayo Clinic indicated that about half the children diagnosed with ADHD were also diagnosed with a reading disorder (Mann,2010). In other cases it might be that speech cadence, vocabulary and other nuances learned in the home environment differ so markedly from the content of reading passages that the integration of natural and visual language cannot occur with adequate proficiency. To wit, if the child cannot read in the same way he talks, the new (to him) academically – scripted task of learning to read could entail an awkward juxtaposition manifest as schematic confusion.

Beyond Attention…

The fact that many children diagnosed with a reading disorder do not exhibit ADHD patterns suggests other factors are involved. One of which might be social. Language is tethered to social interaction but not all students are highly social. In that context, reading passages that are often descriptive and depict people or creatures interacting, might conflict with some children’s view of the world. While little research evidence research exists to confirm this, some studies have shown that some students are more adept at comprehending mechanical, factual, non-personal reading matter. For instance in a worldwide literacy survey it was discovered that the gap between girls and boys in terms of reading ability was not only significant but widened over time. Yet the study also indicated that boys were adept at reading newspapers, graphic novels, magazines and shortened texts whereas girls preferred and excelled at reading fiction. That suggests that cognitive style, social outlook and gender might play a role in terms of reading proficiency.

Necessary Basics…

That does not necessarily argue for a gender specific reading curriculum – anymore than it would for a math curriculum based on gender, where boys tend to out-perform girls. Moreover, In defense of elementary school teachers, the skill of reading must begin with fundamentals regardless of gender and social orientation. Unless one can recognize letters and words and sound them out, it is difficult to develop any level of fluency. Therefore across-the-board criticism of early reading programs and instructors is unwarranted, especially since elementary level teachers are typically well-versed in child development. That leads to another aspect of the problem, one discussed at length by developmental theorist Jean Piaget.

Schemes – Disequilibrium – Assimilation…

Learning new material entails certain prerequisites. The most crucial is the existence of a priori schemata – i.e. chunks of knowledge, or points of reference to serve as fulcrum, foundation, measuring stick and criteria for comparison between stored memories and new inputs.

Learning does not begin in the classroom. Instead it is initially generated from internal schemata. It is an inside-out process (As an aside, the fact that the teacher is a secondary factor in education provides another reason to abstain from blaming them solely for students’ poor academic performance). Each new input is invariably judged as to relevance and interest in terms of those cognitive schemes. If the input (i.e. teacher’s lesson) is completely in sync with the schemata, i.e. is completely recognizable, it will foster boredom.

Conversely, if the relationship between schemata and input is too discrepant, confusion, cognitive discomfort and task-avoidance will typically result; in which case the lesson will not be assimilated. In order to learn maximally, a certain degree of moderate conflict between schemata and input must incur. Piaget referred to this process as “disequilibrium.”

To maximize learning, input must diverge enough from the schemata so as to be somewhat but not completely recognizable, i.e. be semi-consonant with the schemata. Within that framework the lesson would optimally be some combination of sameness and newness. That juxtaposition is what foments curiosity (as opposed to avoidance and aversion), enhances attention, galvanizes neurological investment, extends memory and most effectively facilitates learning.
Common Core – Yin and Yang…

As discussed earlier, such learning mechanisms automatically lead to a discussion of the much-debated Common Core curriculum. Some, such as Walker (2014) have argued that it works, while others such as Butcher, McGroarty et. al. (2012) have suggested it needs to be overhauled or replaced with something else. Both are right – neither argument is encompassing. For students whose natural language experience coincides with the way reading is taught in school, advanced methods probably do work. For students whose natural language propensities are at odds with the language/reading format used in modern curricula teaching an advanced approach could be not only unsuccessful but counterproductive.

This writer has no ultimate solution to the problem of reading disorders, but one element that can perhaps be gleaned from research and theory on child development – as well as from the distinction between natural and visual language – is that certain questions and principles can perhaps be applied in addressing the problem. For example, educators might inquire as to…
1. Whether students’ schemata match the content of the reading curriculum.

2. How a teacher can evaluate the scope and particulars of those schemata – especially in large classrooms, for instance through use of a life/language experience scales (formal or informal) and interest surveys gleaned from discussion with students or submitted by parents when students cannot articulate such preferences.

3. How a conversational language sample from the student might help in gaining a sense of cadence and vocabulary so as to create a close match between the student’s natural language and the content of the reading language.

4. Whether there are ways to blend the natural flow of language with the restrictive, associative aspects of early reading skills; for example by presenting letters of the alphabet in conversational form, e.g.… A is for apple, which goes good with candy at the amusement park, and you can also put it in pies for Thanksgiving. You all like apple pie, don’t you?..Alright then, A is for apple. Meanwhile, B is the first letter in the word bee – and no one wants to be stung by a bee. Anyone been stung by a bee. Ouch!! B Is it also the first letter in the word baseball, and by the way, are there any Red Sox fans in this class? Maybe one day some of you will play on a team. Maybe you have older brothers or sisters who play on a team now – anyone? Once again, B is for baseball.

5. If there is a way to create disequilibrium – the precious semi-recognizable discrepancy between schemata and teacher input that maximizes learning functions. Here the answer might be surprisingly simple. It can be done by adding questions to the lesson. For example. A is for apple, and you can put apples in pies, you can bob for them in a contest – anyone ever put their head in water to pull out an apple and win a prize? By the way, there must be other places where you’d find apples. Can anyone tell me if there are other foods or a drinks where you’d find apples?

The general point here is that the more student-centered the lesson the more likely it is the student will learn to his or her actual ability.

Conversely as the curriculum drifts more toward a central, systematized approach, the fewer number of students will be accommodated in the achievement equation. In the final analysis, this argues for the time-honored notion that the prime variables in education are the scheme, the teacher and the student rather than data-drive curricula, methodologies or standards geared more toward homogenizing students than toward reaching and teaching as many of them as possible.

God and Mind: A Psychological Perspective

By Robert DePaolo

Abstract

This article discusses the human tendency to believe in a higher power in an integrative psychodynamic/religious context. The argument is presented that, regardless of the validity of any given religious system, a psychological mandate exists which compels mankind to exert control over his world and to adapt when that imperative is frustrated.

Genesis…

Any attempt to determine just when and why mankind developed spirituality is fraught with complications. In order to draw conclusions on that topic, one would have to take into account a number of neurological, anthropological, social and experiential factors. For example, how large does a brain have to be in order to integrate the cognitive, linguistic and emotional faculties needed to make such beliefs possible? Moreover, even if a brain has that potential, what socio-political phenomena have to be in place before a need for spirituality arises? Would God have summoned Moses to Sinai if the Egyptians had not enslaved his people? Would Jesus of Nazareth have sacrificed himself if not for Roman oppression and his perception that fellow Jews had drifted from the Torah? Even beyond that, did Moses and Jesus have to be of a certain psychological disposition in order to embark on their quest? Such questions are so intertwined as to preclude clear delineations of cause and effect.

One the other hand, whether one is religious, agnostic or atheistic, there would seem to be certain prerequisites in adopting a religious belief.

One requirement, as suggested by Lee (1995) and McArthur (2007) would be a state of duress. This is based on the notion that belief in a higher power derives from a state of helplessness or oppression pervasive enough to prompt the search for a hero or savior among a significant number of people. That dynamic existed during the early development of Judaism and during the early development of Judaism (Clayton, 2006 ) Christianity (Wylen 1995) and Islam (Lapidus 1988).

The question is whether that would be sufficient. For example, religious beliefs were strong during the Davidian era, when Israel wielded considerable power in Judea. In addition, strong religious beliefs existed within Roman society, despite their widespread dominance over vast Eurasian territories.

Despite “duress theory” it is conceivable that the belief in God has little if anything to do with historical forces, and that some fundamental trait inherent in our neuro-psychological wiring lies at the root of a search for transcendence. Some have even suggested that such a belief trait might not be quintessentially human. For instance, anthropological evidence seems to indicate that the Neanderthal peoples believed in an afterlife (Vegas 2011). While evidence for a specific godhead is scant among these archaic humans, it is not unreasonable to assume that if they conceived of a life after death, they must have filled in the blanks about the nature of that spiritual life – including a supervising entity responsible for orchestrating the vicissitudes of life and natural events.

Even more interesting is the possibility that a most basic root of religious belief can be seen in primate social groups, where rank order is essential in maintaining their solidarity. Chimp alpha males and females typically regulate behavior patterns, especially males, by instilling a fear-based sexual taboo through chronic vigilance and assaults on lower ranking males who attempt coitus with females during estrus. The end result is that while lower ranking males find ways to access females in estrus, dominance determines paternity to a large extent (Newton-Fisher, Thompson et. al. 2010). In addition, lower ranking members typically bow in deference before alpha males when the behavior of the former have come into question.

In that context, one could argue that adherence to hierarchical dominance, coupled with evolutionary enhancements in human cognition and language might have made a belief in and need for God inevitable for the human species, not just as a spiritual force but somewhat ironically, as an adaptive cognitive trait for maintaining social order for primates, whose large brains create vast permutations (good and bad) in social behavior patterns.

If that argument has validity, and if the alpha male (or female) comprise primate prototypes for God, one might expect humans to blur the lines between God and man. The historical record lends support to that assumption.

For instance, dominant males were viewed as gods in ancient societies; Ramses of Egypt, Constantine of Rome and Alexander of Macedonia, being among the most prominent. Beyond that, the distinction between earthly leader and God were often blurred even in monotheistic religions.
For example both Jesus and Isaiah were born of human flesh yet were elevated beyond mortal status by virtue of the fact that, unlike most common folk and even lower prophets they ascended into heaven after death to sit beside the Father.

Still, while the hierarchical process might explain some aspects of god worship, it leaves explanatory gaps. The most obvious revolves around the question of why Homo sapiens would need a transcendent god when human gods (alpha males) would be just as functional in sustaining social order and behavioral codes. For that reason, it seems one has to go beyond the primate word to gain a more comprehensive understanding of human spirituality.

Divided Morality…

A complete assessment of the origins and human impact of religion must take into account the various functions of God in a pagan system. The Greek and Roman deities were hierarchical, but also in many ways operated within divisions of labor – an interesting parallel to their systems of republican government.

The obvious flaw in the pagan model is that having various godheads, each with specific function could lead to clash among them – as often occurred in Greek Mythology. Having moral supervisors caught up in endless conflict amongst themselves would hardly be conducive to maintaining socio-moral order. From that perspective, it is not surprising that Monotheism out-lasted paganism as a religious model over time.

Paterfamilias…

Another theory on the origin of religious worship was that of Sigmund Freud. He wrote that God is symbolic of the father figure, whose presence is necessary to restrain man’s violent impulses and maintain social order. (Armstrong, 1993) In some ways this is similar to the primate argument and has similar flaws. For instance it does not explain the existence and historical importance of female deities such as Shiva, Hera, Isis and Duttur – the mother of Tammuz, the Babylonian god of fertility. Nor does it address the fact that males are more prone to aggressive behavior. Having male Gods regulating morals through violent retribution – a trend seen in every religious text, including the Old Testament, (Acts 1:9-12), (Nahum 1:2) wouldn’t necessarily serve as a model of restraint. Clearly the laws and punishments of worshippers would be derived from the behavior patterns of the Supreme Being; as the stoning of adulterers, cutting off the hands of thieves in Mesopotamian cultures point out clearly. In fact, violent retribution was so much the norm in the early agricultural settlements that one has to wonder what modern society would be like today if not for revolutionary thinkers like Jesus, who reached back into doctrinal antiquity to resuscitate the idea of compassion and forgiveness, and Siddhartha Gautama who created a new spiritual template based on a presumed unity among all living things and a life style of simplicity.

Since theories of alpha dominance, father-symbolism, republican-paganism and hero-seeking would seem incomplete in explaining man’s penchant for religious belief, it might be interesting to discuss a more basic, psychological root of spirituality.

A God of Persistence…

As an introductory comment; the following discussion does not preclude the existence of an actual God, especially as a force of nature, not necessarily corporeal or personified but woven into the actual physical universe and certainly into the neuro-functional structure of the human mind.

For purposes of discussion, one can assume that on some level the idea of God is existential. That is, in order for God to exist and impart moral codes to mortals requires communications between himself and his audience (mankind). In other words if God had selected a chimp to climb Mt. Sinai, things might not have worked out so well (please pardon the reductio ad absurdum premise). Therefore one precondition of faith is the potential for a meeting of minds between mortals and God.

The “mortal” side of such reciprocity is a bit easier to explain because it can be found in the makeup of the human mind. Our brains are wired to control our environment. With fronto-parietal circuits in the cerebral cortex devoted to fine motor controls and speech precision, we are not only capable of prompting, categorizing and manipulating our world with language but also of extending such controls from mouth to hands along the motor strip so that we can make tools to actualize those categorical possibilities.

However it isn’t just the doing and talking. It is also a psychic mindset (a kind of internal metric) creating an expectation of control; a notion discussed eloquently by Bronowski (1973) One suspects that in the course of human brain evolution emotional circuits in the limbic brain networked with the control centers in the fronto-parietal catch-area so that feelings of satisfaction or frustration could result from successful or unsuccessful attempts at controlling tasks and circumstances. Lending support to this argument is the work of Mansell (2010) who demonstrated that feelings of pleasure and the onset of psychopathology are very much related to the perception of control or lack thereof.

In that context, there are certain elements of the control dynamic that play out in human psychological functioning. One instance occurs when control is attained and positive feedback signals prompt a pleasurable emotional response. Another occurs when attempts to exert control are frustrated, at which point anger and other negative emotional reactions occur in accord with the classic frustration/aggression mechanism (Berkowitz 1993). A third occurs when continuous attempts at control fail, the actor abandons his behavioral strategy and reverts to repetitious behaviors as a means of overriding goal frustration. The repetition pattern, often referred to in clinical circles as vicious circle behavior, typifies many types of psychopathology (Melvin 1979).

Obviously neither anger nor mere (neurotic) repetition is adaptive since a prolonged state of anger is both emotionally taxing and socially inappropriate. While creating the temporary illusion of control mere repetition seldom leads to response satisfaction.

That is where a fourth and more adaptive response tactic comes into play. It occurs when, after unsuccessful attempts at control, the actor is able to reverse the relationship between actor and object; by in effect resetting an internal gauge. At that point he becomes a function of the original target rather than vice versa. In so doing he relinquishes his status as controller and puts himself at the mercy of external circumstances.

The cognitive transition from the controller to the controlled alleviates tension and is thus negatively reinforced. That is because the feeling of relief resulting from relinquishing control feels good and will be repeated when similar circumstances arise again.

But the process does not end there. Despite relinquishing control the person still needs closure, i.e. some sense that the task will have an endpoint. In order to be deemed a controller, he must be deemed an actor and thus be assigned an identity. For example, the uncontrolled predator who took his son might over time be viewed as a god. The uncontrollable climate pattern would after an extended cold spell, become personified and deified. Perhaps the sun would be deemed a benevolent god, the wind a vengeful god via this conversion process.

In that context, the person would defer to and personify things he could not control, leading to attributions and the search for a hero or entity more powerful than he whose powers could help or harm him.

Still, the idea of faith fueled by psycho-adaptive submissiveness in a creature whose neuro-behavioral features emphasize control does not answer the question of how religious beliefs became so entrenched through the ages despite technological advancements that enables us to increasingly control more aspects of our environment.

One reason might be because science cannot ameliorate the need to exert control in most aspects of life, including relationships, personal feelings and concerns about things that have yet to happen. In other words, science can never keep up with the totality of human experience.

Aquinas’ Conundrum…

Since no single idea on religious origin is likely to be complete, it seems fair to ask what this conversion/submission theory implies about the existence and nature of God? For example, is God real or imaginary? Ethereal or man-made? A human-like figure (with muscles, bones and blood modeled in his image) or an amorphous entity with some sort of mysterious plan mankind might never come to understand?

Such questions are abstract and will probably never be answered definitively. On the other hand, that is what makes speculation so inviting – thus the following.

A Concept…

To begin with, while the word God will be used here for convenience sake, the term God is presumed to be a force, potentially discoverable through physical laws) that regulates the natural world but as an existential entity operates primarily through the operations of the human mind.

Now, with respect to the questions raised above, some answers are ponderable; especially if, as mentioned above, one views God as a driver of human cognition.
In that context, one can assume God was not created by man because man did not create his own mind, or its capacity to reset the neuro-cognitive gauge in reversing the natural tendency to exert control. (One could argue that was the true intended message in Genesis). As for God’s plan, and as a corollary, whether He is inherently benevolent or vindictive, it seems by granting humans a capacity to convert their penchant for control through submission He has revealed both His plan and modus operandi. It is to provide us with the gift of persistence. In accord with that notion, one could presume (for example) that He does not take lives – that’s out of his control. Instead He provides a capacity for mourners to persist in the aftermath of a loss. Nor does He punish transgressors. Instead He provides them with a capacity to adopt a more humble and submissive mind-set in deferring to laws and moral codes. Whether or not they take advantage of that capacity will determine their fate, and is ultimately up to them. (That is where the lines between free will (which most religions accept as a given) and the implied ultra-deterministic governance of a deity intersect.

This speculative account argues that God goads us on, implores humans to maintain their individual and collective momentum. He is more than a mere psychotherapist, yet perhaps his purpose is similar to a process described by Carl Jung, who wrote that life unfolds in alternating patterns of growth and stagnation – laughter and sadness served up like a day to night transition. Those who learn to accept temporary stagnation, indeed use it as a rest period in restoring energy will once again be able to regain control, at which point good deeds and human creativity can once again emerge.

The arguments rendered above are, of course, merely philosophical. They do not address the many questions about the nature of God pondered by theologians over time. For that matter the notion that faith’s origin lies in a coping strategy could be deemed reductionist. On the other hand something within the laws of nature gave us a brain with which to control our world in ways not possible for other organisms.

Such a thrust-forward cognitive style can be both advantageous and detrimental. The same need to create, explore and resolve can also destroy us. For every sky scraper we construct, for every poem we write, awaits a stress reaction in circumstances where control is thwarted. If having the ability to persist and survive by altering our internal dispositions was the only gift from God, it would be not only spiritual but all in all, a pretty good deal.

The Neurology of the Ego: Implications for Diagnosis and Treatment

By Robert DePaolo

Abstract

This article discusses a neo-Freudian view of ego function, as a mechanism not dependent on a specific element of a triadic psyche but as a checks and balances process modulating extreme, unilateral thoughts, emotions and behavior rising quite naturally from multi-access to cognitive templates widely scattered in memory throughout the brain. The argument is presented that self-regulation and impulse modulation (two functions of the ego) require both storage of and access to varied thoughts. attitudes and behavior patterns which by their very diversity, preclude the emergence of extreme, linear non-contextual emotions, thoughts and behaviors. The argument is presented that compulsivity (linearity) rather than anxiety comprises the essential psycho-pathogen and potential focus in psychotherapy.

The Freudian Ego Function…

While Sigmund Freud is presumed to have broken new ground via psychoanalytic theory, his model of the psyche was somewhat derivative. As a young intellectual he was influenced by new and provocative ideas; one of which was Darwin’s theory of natural selection. In ‘Origin’ Darwin wrote about the evolution of various organisms and implicitly about the descent of man. He also painted a less than benevolent view of the natural world in which competition, sexual opportunism, aggression and cunning were essential criteria in determining fitness.

Freud’s theory of personality revolved around this concept but whereas Darwin was concerned primarily with the broader functions of the biotic world and stopped short of trying to explain how humans can be at once competitive, aggressive, sexually opportunistic and altruistic, compassionate and cooperative, Freud, blessed with a psychiatrist’s more comprehensive take on human nature, felt addressing such polarities was necessary in defining the functions of the human psyche.

Darwin wasn’t the only influence on Freud. Other revolutionary ideas were emanating from the field of science at the time as well. One in particular was Helmholtz’s notion of energy constancy – the idea that energy cannot be canceled out, but can only change from one form to another (Cahan, 1993)

In addition to Freud’s sheer genius it was the juxtaposition of those two ideas – energy dynamics and natural selection that provided a framework for the development of psychoanalysis.

This is not to diminish his massive contributions to modern clinical practice because as is suggested in cultural-ecological theory, genius has less to do with the creation of new ideas than with the creating a new synthesis out of old ones.

In developing his model of mind Freud began with two postulates. First, he believed that the mind must be viewed as an energy system that can change form as a result of outside influence – as water changes to ice when frozen and vice versa.

Implicit in his thinking was that the capacity of energy to flow from one source to another (in accord with the third law of thermodynamics) enabled it to move around the psyche depending on need and be drive by experiential mandates, including changes in social norms. It meant that at times, mind could focus on atavistic needs, but then be transferred to other functions as society became more populous, sedentary, agricultural and rule-governed – thus requiring greater behavioral restraint.

It was a brilliantly conceived idea, and one that despite criticism by modern thinkers is hard to refute in both biological and ergonomic terms. That is because the underlying premise of psychoanalysis was that man is part of the natural and physical world and therefore must operate within its parameters.

The Problem – From “What” to “Where” and “How”…

Freud never really attempted to define the psyche in neurological terms – largely because other than Pavlov’s loosely constructed model of the brain (1941) and isolated experiments by Lord Sherrington (1932) not enough was known about the brain at the time. Since he believed there were physiological correlates of the id, ego and superego Freud no doubt would have addressed this problem.

To a large extent that barrier no longer exists, Given current knowledge about brain development and function there is enough information to speculate about how the ego originates, develops within the brain and how enhancement of its adaptive functions can be accomplished in a therapeutic format. The following discussion is concerned primarily with those issues.

The Psychic Grid…

The brain of a child undergoes a number of changes in development. One has to do with a process known as meshing. Between the ages of 6-12 months neural fibers are connected primarily in vertical fashion. During this period the child accrues piecemeal associations in auditory, linguistic, motor and perceptual systems at a rapid rate but these associations are not highly integrated. One reason a child becomes upset over loud noises is because the noise has a singular impact on the brain. Once the child develops more enhanced, integrative cognitive and perceptual capacities it can use attribution to modulate the effect of loud noise; for example recognizing it as the sound of a playful adult or a toy. In that sense associative breadth not only serves as a language reference point but also as a stimulus buffer, potentially ameliorating the impact of what might otherwise be overwhelming inputs.

As brain development proceeds, a meshing process occurs, whereby horizontal fibers cross over vertical pathways, thus creating a grid-like structural and functional system. The grid format creates greater multi-accessibility. It represents a vast cognitive improvement on the previously vertical and experientially raw and narrow processing capacities of the toddler.
As meshing occurs, cross references become more voluminous and at that point what we call experience takes on a whole new meaning. In some ways that is a bad thing, because pure experience becomes swayed and distorted by interfering cross circuits – like a party line in the old telephone systems. Because of the meshing process pleasure, irritation, love and hate are subject to qualifications and confusion. This can blur one’s view of the world, of social relationships and ultimately of self-definition.

In other ways it is a marvelous thing because meshing provides three significant psychological benefits. First, as discussed earlier, it serves as an experiential buffer, taking the sting out of aversive experiences by broadening and diluting them into tolerable perspectives. Due to meshing, funerals can be sad but also mark a celebration of one’s life. Defeat can be disheartening but then become a stimulus to future success. Tragedy can be debilitating, that is until one decides it is God’s will. Then calmness ensues. Thus the neural cross-grid mechanism enables humans to convert experience into more tolerable forms, allowing us to move forward despite setbacks.

A second benefit is that a cross grid brain mechanism forces deliberation. All inputs are, under normal circumstances, cross-referenced. They are in effect gobbled up by the breadth of the grid. That slows down the thought process, makes it more likely that emotion will be accompanied by cognition, gives us time to plan, rehearse our actions, and thereby render them more effective. Postponement of gratification – especially with some expectation of even greater gratification down the road – become possible.

A third benefit has to do with what might seem a drawback to the meshing process – uncertainty. Cross-referenced experience is by definition no longer pure and unadulterated. It is, in a sense, muffled by peripheral inputs. Some byproducts of that integrative tendency are uncertainty, and a substantial expenditure of psychic energy to attain closure on experience.

The temporary irresolution arising from meshed brain interference patterns leads to something called creativity. That is because (perhaps unbeknownst to some modern educators) the human brain is more a conflict-resolving organ than a fact finding machine. It prefers questions to answers and abhors dogma. That is why, a certain trend holds true in the classroom; one of which is that the more the teacher asks, the greater student investment. Conversely, more dictating and pre-resolution tends to diminish student investment.

That mesh-driven tendency to create neural checks and balances, modify experience and foster uncertainty enables us to create not just ideas and skills but to create self-images as well.

All things considered. that should lead to the development of a healthy and functional ego, and people should end up patient, self-aware, confident, organized in thought and behavior, with perspective sufficient to override impulse and ego-centricity. Unfortunately things don’t always turn out that way and that is where a re-definition of the ego becomes relevant.

Neurological correlates – the integrative mechanism…

Research led by Courchet, Polleux et al (2013) offers a more in-depth description of how meshing occurs and why in some instances it does not. He discovered that, particularly in the cerebral cortex, an enzyme known as kinase LKBI transmits a signal to a second enzyme (Kinase NUAKI) which in turn mobilizes mitochondria in immature brain cells. The motility and transference of mitochondria provides the chemical energy needed to produce extension of dendrites across the brain and thereby create the cross-grid effect. Absent that mechanism brain cells remain disconnected or at best meagerly interconnected. As a result, sensory integration is compromised (as are the other benefits of meshing alluded to above). As a side comment; the Courchet-Polleux study noted that a disruption in this process has been observed in autistic and Alzheimer’s patients.

To infer from this that the neural substrates of the ego is genetically, and biochemically driven might seem a bit simplistic; especially since many clients with poor ego development exhibit no apparent neuro-pathologies. On the other hand meshing can be subject no non-genetic influence.

The cross grid connections between brain pathways can also be effected by experience. This can be seen in a triadic interaction within the brain during maturation.

Pruning…

There seems to be a temporal coordination between meshing, frontal lobe development and a restructuring of the brain in general. Frontal development has spurts and lags in child development, beginning in the first 6-12 months and then off and on until just before adolescence, when the largest growth spurt occurs. During these growth stages, there is a concomitant discarding of brain tissue via a process called pruning (Chechik, MeliIjsm et al (1999), (Low & Cheng (2006). Discarding of excessive brain tissue runs parallel to frontal expansion. Under ideal circumstances this should not pose a problem either emotionally, cognitively or in the capacity to integrate experience. That is because meshing and frontal expansion facilitate integrative thought, which makes detail memory less important and allows the brain to be less specific in its analysis of the outside world. For example once a child learns the integrative term fruit, he can, from that conceptual vantage point reference any number of specific details. As a result he no longer needs to establish specific, isolated pathways devoted to memorization of apple, orange, peer, etc. In simpler terms, integrative, conceptual thought, ameliorates a reliance on details in memory retrieval.

The problem with pruning, however is that it is subject to experience and falls under the rubric of use it or lose it. In childhood discarded neuronal cellular pathways are typically those used least frequently. In effect, the brain decides what pathways are essential on a probabilistic basis. Those most often used are retained, those seldom used are discarded. Interestingly, some research has shown that the pruning process is carried out though phagocytosis (Smith 2011 ) – as if seldom used neurons are somehow “viral” and by inference physiologically harmful by their presence on the brain. If this proves accurate it would provide significant insight on the relationship between cognition and neurobiology.

Thus it is possible for the brain of a child who seldom experiences, observes or uses empathic behavior patterns to shed pathways infrequently employed for that purpose. That doesn’t necessarily mean the child will be incapable or empathy as he matures, because the human brain is malleable enough for some pathways to compensate for others. However, it does mean, that like the young stroke victim who regains speech after a head trauma, re-learning empathy will be difficult process. Meanwhile the higher probability pathways are meshed together in development to form new non-empathic neuronal templates.

With regard to the advent of psychopathology, herein lies a problem. Just because neurons that might be devoted to social interest and empathic development, including:
1. An ability to recognize emotional features reflected in facial expressions and voice tone.
2. Expectation of receiving nurturance from others.
3. A history of being reciprocally reinforced for responding empathically to others…
are discarded due to infrequent usage does not mean the non-empathic person operates in a superego-depleted void. More likely is that an intra-personal conceptualization will develop which revolves around the self.

In such circumstance, the frontal lobes might function in a neurologically intact manner but be primed to conceptualize experience in an egocentric fashion – thereby justifying the psychopaths anti-social acts based on his perception of being slighted or victimized. For diagnostic purposes it would signify that ego-centric psychopathologies are not the result of a neuro-experiential deficiency but of a re-synthesis around the self. In other words the superego of the socially detached individual would be presumed intact but internally governed –with conscience and self-preservation/ gratification being two sides of a single coin.

Brass Tacks and Re-definitions…

The pruning process, as it relates to frontal maturation coincides with Freud’s view that the ego is learned through social experience. The difference between his definition of the ego and the one offered here is that this version is ostensibly broader in scope. It is presumed to develop not just to compromise between conscience and impulse but as a facilitator of creative thought, as insulator against aversive experiences and as an uncertainty inducing precursor to cognitive resolution. That has significance with respect to the human evolution model espoused by Freud.

Tools for Survival…

Freud believed the human psyche had its roots in the advent of agricultural civilization. In the sedentary confines of urban settings, families remained intact to satisfy work requirements. Since agricultural production could feed larger groups of people, heavily populated towns rose up which entailed greater para-familial alienation, social conflict and sexual competition. Freud’s assumption was that during this time psychic energy had its first migration from the id to the superego and ultimately the ego.

The neurologically-based ego model here harks back a bit further in time, specifically to the epoch in which homo sapiens – with his fully developed brain of some 1500 centimeters – arrived on the scene. It was during an Ice Age and survival came hard. Fortunately the large brains of our ancestors provided two significant tools enabling them to persist. One was the finely honed circuits around the fronto-parietal lobes supporting enhanced manual dexterity, spatial perception and the oral-motor precision that gave rise to a broader phonetic vocabulary leading to improvements in the crafting of tools, the use of communicative signals for hunting, cooking, making clothes and for the use of fire.

A second tool was equally important. It was a neurologically-driven capacity to distort experience – via the meshing of vast networks, so that pain, discomfort, tragedy, hunger, cold and hopelessness could be diverted. That ego – that capacity for intra-cerebral consultation and experiential modification enabled the inhabitants to press on in circumstances to which their hairless, slender, bipedal anatomies were not inherently suite. In that context, the first function of the ego, according to this model was the creation of hope and futuristic cognition. Such musings are not typical fare in discussions on human evolution but it’s hard to imagine humans coping in the Ice Age without such psychological resources.

Human Nature and the Moral Conundrum…

As mentioned earlier, in addition to its benefits the meshing process serves to distort pure experience. Life per se is edited constantly due to the obligatory intra-consultations that occur in the integrative mind of man. That somewhat curious feature is something of a paradox when it comes to the brain’s structural and functional impact on human civilization.

The paradox is this. The same distortion that leads us to generalize experience –which can take the form of racial stereotyping and hyper-emotional labeling (what Albert Ellis referred to as “catastrophizing” (2001) also enables us to create concepts known as rules, which in the final analysis enhances our ability to get along with one another. Thus human brain development, like everything else, involves a cost vs. gain trade-off.

In that context this model of the ego can be considered both psycho-socially adaptive and potentially problematic since it is forced to compromise within itself rather than acting as detached arbiter.

Theoretical Comparisons…

The question could be asked as to whether the neurologizing of the ego still coincides with Freud’s tripartite model of mind, i.e. as a modulating function amid id and superego. In one essential way it does not.

For Freud the primary psycho-pathogen was un-channeled anxiety. Here it is something else. For example, while an ego that derives from meshing and pruning would have an integrative capacity, both the id and superego would be viewed as non-integrative processes; – not separate elements of mind but a manifestation of networks operating outside the parameters of broad neuro-experiential consultation. In the case of the id, atavistic impulses, including sexual urges, aggression, a-moral opportunism could be described as a reflection of narrowly-driven, piecemeal acts and emotions. Meanwhile, the singularly moral, guilt-laden impact of the superego would be similarly defined as narrowly driven. Both would be typified by psychic tunnel vision.

According to this model, many forms of psychopathology would result from limited access to broad neural consultation and would therefore be described most fundamentally as a form of compulsion. By the same token the treatment of psychological disorders falling under this category would involve a search by client and counselor for broader thoughts, experiences and memories to create a psychic check and balance system and be used as both a here-and-now curative agent and preventative strategy against future breakdowns.

Implications for Diagnosis and Treatment…

While much of the modern literature on psychopathology is veering toward biological root causes, one can apply this model to treatment of the less obviously biological syndromes. The key to such an approach would be two-fold. One component would be to label and confront the narrow interpretations of experience that sustain the pathology. Once the “maladaptive tunnel vision” is discussed in counseling, use of broader labels and attribution can be broached, enabling the client to develop a more broadly consultative psychic system. Increasing neuro-experiential breadth and frame of reference in this phase of counseling could involve traditional sessions, discussions, reading materials, group sessions, or conceivably any other information-gathering mechanism.

A third phase of counseling would be didactic, and it would involve practice in session at re-labeling experiences so as to broaden the intra-consultative capabilities of the client. Once consultative skills improved, not only would the client be able to resolve presenting problems. He could also provide himself with a buffer against subsequent duress for post-therapeutic experiences.

Snags – the Counselor’s Moral Responsibility…

The obvious drawback of such a method would be that clients could learn to intra-consult their way past the socio-moral codes by which most of us live. One of the elegant aspects of Freud’s ego model is that it is both internal (anxiety-reducing) and external (used to accommodate social norms). In that context, it would be up to the counselor to guide the client toward reasonable, rational consultative resolutions that buffer experience, foster creativity but remain consonant with social mores.

Another drawback to this method is that being able to juggle social norms and consultative breadth to facilitate functioning and ameliorate compulsive, narrow percepts, behaviors and emotions would require adequate cognitive and language abilities. In that sense it suffers from the same limitations as most talk-therapies which modern clinicians have yet to overcome.

The Cognitive Singularity: Pleasure, Agreement and the Nature of Mind

Abstract

This article discusses cognition as a broad phenomenon, not restricted to brain function or organic complexity but rather as a process that is pervasive throughout nature. The argument is put forth that traditional definitions of cognition might be anthropocentric, that cognition and decision making occur even in the simplest biological configurations and that a more fundamental description of cognition can be developed by examining the roles of informational agreement and pleasure in the pre-cephalic natural world.

Cogito Ergo Sum…

Belief in the idea that cognition emanates from a specific organ (the brain) and can only result from a higher consciousness (the mind of homo sapiens representing the apex of such a capacity) has been passed down through the generations. While this discussion will ultimately attempt to refute that notion, it is not without face validity. Of course we are able to think, make decisions, predict and to an extent control our environment. Some have said that is what makes us human, and in some sense, biologically transcendent, (Bronowski 1973).

On the other hand, human cognition is a funny thing. The same capacity enabling us to think about ourselves, or own immortality, strengths and flaws also leads us to internalize experience and funnel it back into an egocentric mode beyond the concrete world. That can lead to flawed ideas on how nature really works. The trick to understanding nature is to divorce ourselves from that mindset, and in order to do that requires an operational as well as linguistic definition of knowledge.

For example, it was a human who conjured up Special Relativity Theory and made it available through literary communication. Yet birds seem capable of adapting to and operating on the principles inherent in it. Thus they can be said to have non-linguistic knowledge about this phenomenon. Similarly, while the architectural designs of Frank Lloyd Wright and Christopher Wren are of human origin, a spider could also lay claim to a non-symbolized but similarly operative capacity. And, while paleoanthropologists have long believed that human civilization resulted from the discovery of agriculture, leaf cutter ants figured out long ago how to plant fungi, wait for it to ferment, then consume it. Furthermore, well before man, insects developed highly complex societies, with fixed roles, social hierarchies and threat-negating group cohesion (anyone who has been attacked by a swarm of wasps after disturbing a nest can attest to that). And while
