Schizotypal traits and neuropsychological performance: The role of processing speed.

ABSTRACT:

Background

Cognitive deficits, particularly in processing speed, are widely recognized as a critical feature of schizophrenia, and are also present across schizophrenia spectrum disorders. A number of important confounders, however, such as hospitalization effects and antipsychotic medication, have been shown to affect processing speed, causing debate as to the core cognitive deficits of schizophrenia. The study of individuals who are not clinically psychotic but have schizotypal traits allows investigation of cognitive deficits associated with both positive and negative schizotypy dimensions while excluding potential confounds.

Methods

A population-based community sample of 242 healthy adult volunteers assessed using the Structured Interview of Schizotypy - Revised (SIS-R)
