[Kinship lexical organization and psychosis]

The main goal of this study was to investigate the use, by schizophrenic and manic-depressive patients and by those suffering from mild reactive psychoses, of parental lexical terms. Based on five questions that evaluate the classical dimensions of parental relationships, we tried to ascertain the different types of errors that occur, and their relationships with the psychoses under study. The results revealed a greater incidence of errors in the questions linked with the generational dimension. This work corraborates the difficulty of psychotic patients to establish the differentiation among generations.
