This study was designed to investigate implicit memory which depends on automatic processing in positive and negative schizophrenic patients. In experiment, the retention of unattended words by selective attention procedure was examined. Gradual perceptual identification test as implicit memory task and recognition test as explicit memory task were administered with attended words and unattended words in test phase. The results were that evidence for retention of unattended words was found in normal subjects but was not found in schizophrenic patients. There was not significant difference between positive and negative schizophrenic patients. These results suggest that schizophrenic patients are impaired on explicit memory which require conscious recollection. But Implicit memory on attended tasks was relatively preserved to explicit memory.
