34 schizophrenic patients and 34 general medical patients were given tasks which involved the spontaneous and later forced ordering of a series of future events, 4 stories in response to verbal instructions which included the beginning of each story, and estimates of the age of occurrence of 15 future events supplied by the examiner which were later placed in order of expected occurrence. On the basis of these tasks, measures of 2 aspects of future time perspective, extension and coherence, were derived. The obtained results support the hypothesis that future time perspective is significantly affected by psychopatho-logical disturbance. 21 references.
