TL;DR

The ‘unusual perceptual experiences’ factor is found to be related to performance of both incidental learning tasks and there is a trend towards it being related to the second of two Kamin blocking tasks.

Abstract

Performance of Kamin blocking and incidental learning tasks has been found to be significantly affected in acute, positively symptomatic, subjects. However, a previous study of normal subjects failed to show any relationship with schizotypy. The present study reanalyses these data in the light of Hewitt and Claridge's three-factor solution to Claridge's schizotypy scale. The 'unusual perceptual experiences' factor is found to be related to performance of both incidental learning tasks and there is a trend towards it being related to the second of two Kamin blocking tasks. Results suggest that this more sophisticated approach to schizotypy may enhance correspondence between findings in schizophrenic and 'psychosis-prone' normal subjects.

Findings support previous findings suggesting that different schizotypy scales relate to different underlying aspects of schizophrenia and indicate that psychotic traits are distributed along at least three dimensions.

It is found that arousal is a major determinant of changes in patterns of information selection in visual monitoring tasks and in loud noise, subjects attend more to sources of information of “high priority” and are more likely to disregard sources of less important information.

It is concluded that Social anhedonia and Psychoticism represent a separate dimension from other scales which reflect the more positive features of schizoid personality.
