Forty-six hospitalized chronic schizophrenic patients and outpatients were tested with EFT (Embedded Figures Test), KBDT (Kohs Block-Design Test) and PIT (Picture Identification Test made by ourselves) to discuss their attention and visiospatical function. Patients were divided into 3 groups; 20-39 years, 40-49 years and 50-58 years. In the schizophrenic group both the scores of EFT and KBDT decrease in the function of age, especially showing sharply declined EFT scores between the 40-49 group and the 50-59 group. Also, the score of PIT in schizophrenic patients lowered in comparison with the one of normal group. It is noted that schizophrenic patients firstly begin to detect these missed points around the center in contrast to the normal group. Hence, it was suggested that chronic schizophrenic patients might have cognitive dysfunction related attention and visiospatial function.
