Cognitive slippage in schizotypic individuals

The Miers and Raulin Cognitive Slippage Scale was used to assess subtle tho ught disorder, and the Wisconsin Card Sorting Test (WCST) was used to asses s cognitive performance in deviantly high scorers on the Perceptual Aberrat ion and Magical Ideation Scales (N = 63), high scorers on the revised Socia l Anhedonia Scale (N = 62), and in control subjects (N = 83). Results indic ate that schizotypic individuals are more likely to report greater cognitiv e slippage and less likely to achieve as many WCST categories as controls. Individuals with both positive and negative symptoms of schizotypy reported higher levels of cognitive slippage than those individuals reporting only negative schizotypy. Additionally, the results confirm the presence of an e specially high-risk group of psychosis-prone individuals, namely, those ind ividuals with deviant scores on the revised Social Anhedonia Scale who poss ess additional indicators of schizotypy.
