Visuoconstructive performance, implicit hemispatial inattention, and schizotypy.

The present study investigates visuoconstructive performance and hemispatial inattention in schizotypic college students and control subjects using the Rey-Osterrieth Complex Figure Test (CFT). Both copy and delay CFT accuracy, as well as line bisection scores on the CFT, were examined in right-handed males reporting positive schizotypy (deviantly high scorers on the Perceptual Aberration and Magical Ideation Scales; n=24) and those reporting negative schizotypy (deviantly high scorers on the revised Social Anhedonia Scale and Physical Anhedonia Scale; n=26), as well as controls (n=45). The negative schizotypy group displayed reduced visuoconstructive performance, as measured by performance on both the copy and delay trials of the CFT. We did not find a significant relationship between schizotypy and hemispatial inattention. These findings suggest that negative schizotypy may be associated with memory performance deficits, but do not support prior assertions of a relationship between hemispatial inattention and positive schizotypy.
