Twenty-eight schizophrenics, 36 non-schizophrenic psychiatric patients and 29 normal controls were examined in the tasks of recall and recognition of visual information. Schizophrenics were poorer than normals both in recall and recognition. On the other hand, non-schizophrenics were as poor as schizophrenics in recall, but were comparable to normals in recognition. These results suggest that schizophrenics have deficit in input stage of memory process. The performances of visual short-term memory tasks had significant correlations with the IQ or the Pascal scores of Bender Gestalt Test, indicating that memory deficit in schizophrenia was derived from more primary disturbances of intelligence or cerebral function
