Distractibility in the conceptual performance of schizophrenics.

Abstract

This study explores the role of interfering factors in the conceptual performance of schizophrenics. 40 schizophrenic patients at the Downey Hospital and 25 normals were used as Ss. They were required to sort cards containing 4 figures with 3 four-figured standard cards. One figure on each standard card was arbitrarily designated as correct for sorting. More of the schizophrenics than the normals used the incorrect“distracter” as a basis for sorting, even when conceptual sorting was required. The results support the hypothesis that schizophrenics fail conceptual tests because response to distracters prevents the demonstration of his concept-forming ability.
