Concrete operational stage (Piaget): the fourth stage (of a total of 4) of mental development as formulated by jean Piaget. In this stage, a child acquires intellectual capacities related to hypothetical-deductive thought, which allow him/her to carry out logical operations on the basis of purely hypothetical premises and arrive at the appropriate consequences. This stage starts at around age 12.
Conditioning: a process by which a neutral (unconditioned) stimulus is associated with an artificial (conditioned) stimulus. For example, the sound of a bell (neutral stimulus), which causes an increase in salivation in a dog as the sound is associated with the presence of food (the conditioned stimulus). At this point, the sound of the bell is no longer a neutral stimulus but in turn becomes a conditioned stimulus (cfr. the experiments of the Ivan Pavlov).
Conscious: refers to everything a person is aware of: i.e., memories, desires, sentiments etc.
Conscious repression: a defence mechanism that derives from the awareness with which one tries to intentionally exclude from the region of consciousness, an idea, a fact or a person, to which or to whom in any case an unpleasant sentiment or conflict have been linked. Distinguished from repression in the classical sense on account of the fact it occurs consciously.
Conversion: a defence mechanism through which an internal conflict deemed as unacceptable is expressed symbolically by means of physical symptoms involving body organs or sensory or motor functions. The disorder may present in the form of paralysis, tremors, convulsions, lack of coordination etc. See also ‘Hysteria’.
Counter-transference: this term is used in the psychoanalytical method to indicate specific reactions of the analyst with respect to the patient and the patient’s own transference, such reactions being intended as conscious or subconscious emotional responses to expressions of the patient in analysis.
