Lapsus: an error of speech, which is bizarre, illogical and apparently made casually and for no reason at all. A so-called lapsus linguae or ‘slip of the tongue’ might for example consist in pronouncing a certain word in the place of another word. According to S. Freud, a lapsus reflects subconscious content, which would normally be repressed by conscious censoring mechanisms.
Latency period: the fourth stage of psycho-sexual development, lasting from age 4-5 until puberty. During this period children momentarily leave aside their sexual drives to concentrate energy on productive activities such as nurturing friendships, school work, sports etc.
Latent content: in psychoanalysis, the term refers to the presumed true meaning of dreams concealed beneath a manifest content.
Libido: in psychoanalysis, the energy which provides force to constructive human activities and endeavours. The energy underlying sexuality. The opposite of ‘destrudo’.
Lobotomy: a surgical procedure, whereby certain nerve pathways between the cerebral lobes are cut in the hope that this may produce a positive modification of behaviour. It was once believed this was an effective treatment for schizophrenia
