Temporal information processing and psychopathology.
Prior studies showed impaired temporal discrimination by schizophrenic and neurologic patients reflected in decreased information transmission. This report describes a study of 8 more carefully diagnosed schizophrenic patients, separating those with neurologic signs. Using temporal discrimination tasks involving two psychophysical methods, 8 schizophrenic patients with no organic signs did not differ from 17 nonpsychotic, nonorganic patients; and organic group (n = 5) transmitted less information than the other patient samples. It is suggested that prior results were a product of casual diagnosis that ignored organic factors; reduced efficiency of temporal processing is associated predominantly with neurologic impairment.
