This chapter considers the performance of Cornell University college students on three tasks. The three tasks are delayed response, from which one assesses working memory; antisaccade eye movements, and thought disorder assessed from the Thought Disorder Index (TDI). Two subject groups were composed for the experiments. Group means and standard deviations on the Perceptual Aberration Scale (PAS), computed separately for males and females, served as the basis for group composition. High and low PAS subjects did not differ with respect to sex ratio, age, ethnicity, or consent rate. All subjects were screened for psychosis, and none had a diagnosis of any psychotic illness at the time of testing. The PAS is a well-established 35-item true-false self-report measure of disturbances and distortions in perceptions of body image. Park and Holzman developed a human analogue of the oculomotor spatial delayed-response paradigm to test the hypothesis that schizophrenic patients show working memory deficits.
