Increased repetition blindness in schizophrenia patients and first-degree relatives of schizophrenia patients.
This study investigated the phenomenon of repetition blindness in schizophrenia patients and first-degree relatives of schizophrenia patients. Twelve schizophrenia patients, 13 siblings of schizophrenia patients and 26 normal controls were tested on their ability to detect the repetitions within rapidly presentated visual word lists. Schizophrenics and their relatives showed increased repetition blindness compared with normal controls. This suggests a deficit in rapid information processing in schizophrenia.
