Synopsis

The performance of 21 chronic schizophrenic patients was investigated on two tests of feature selection. It was found that patients with negative symptoms (muteness, withdrawal, etc.) were characterized by an extreme lack of persistence, but selected usual features; whereas patients with positive symptoms (hallucinations, delusions, etc.) had a normal degree of persistence, but selected unusual features.
