PICTURE SEQUENCING BY SCHIZOPHRENIC-PATIENTS

Cognitive sequencing by community-dwelling schizophrenic patients was studied using a new test of picture sequencing designed to minimize th e influence of information-processing speed, visual perception and sca nning, manual dexterity and motor speed, and knowledge of social conve ntions on test scores. Compared with age- and education-equated normal community controls, more than 50% of the schizophrenic patients exhib ited deficits on the picture sequencing test.
