[Some aspects of cognitive activities in schizophrenic patient (author's transl)]. / Quelques aspects des activités cognitives du schizophrène.

Nine paranoid schizophrenics, five control subjects of the same age and four hebephrenic schizophrenics were examined using Piaget's genetic psychology tests. The study of assimilation/accommodation equilibrium in the cognitive activities of schizophrenic patients confirmed our previous results which primarily dealt with hebephrenic patients [12]. The thinking of paranoid schizophrenics is dominated by increased assimilation which explains their tendency to deform observables and their difficulty in generalising reasoning. The assimilation/accommodation equilibrium of their logical operations is affected resulting in: a) difficulty in formulating reflecting abstractions and therefore the comprehension and extension of concepts; b) loss the feeling for logical necessity and a tendency to utilize magical thinking and subjective explanations.

[Choice of symptoms in neuroses. Hysterical and obsessive-phobic neuroses]. / Choix des symptomes dans les névroses. Névross hystériques et phobico-obsessionnelles.

This publication is a first attempt to verify our hypothesis that symptom choice in the classical neuroses depends on a disequilibrium between assimilation and accommodation, in the Piagetian sense, of reflective thinking. Results of tests derived from classical paradoxes of Western thought, from genetic psychology and from a neuropsychological test of the habituation of the alpha-blocking response support the following hypothesis; the reflective thinking of hysterical patients appears dominated by a primacy of assimilation and that of obsessional patients by a primacy of accommodation.
