Associative intrusions in the verbal behavior of the first-degree relatives of adult schizophrenics. A preliminary study.
The first-degree blood relatives of schizophrenics were compared to a matched control group on a psychometrically matched test of responsiveness to associative intrusions. The groups differed on the subtest containing an associative alternative but not on the equally difficult subtest free of associative distractors. Results were consistent with the hypothesis that an overresponsiveness to associative distractors, well documented in schizophrenics, may also be a characteristic of their nondisturbed first degree blood relatives. The possible existence of cognitive markers in the relatives of schizophrenic patients that might indicate familial psychopathology was supported. Limitations of the present preliminary findings, as well as the case for additional investigation of the cognitive behavior of the first-degree relatives of schizophrenics, are discussed.
