Abstract: The present studies examined the effect of schizotypy on performance in a signal detection task. The Oxford- Liverpool Inventory for Feelings and Experiences (O- LIFE) was administered to seventy undergraduate students. The subjects were classified into high or low scorers on the basis of the median split on four measures of schizotypy contained in the O-LIFE questionnaire relating to the positive and negative symptoms of schizophrenia: Unusual Experiences (UnEx), cognitive disorganization, (GogDis), Impulsivity nonconformity (ImNon), and Introverted Anhedonia (InAn). The subjects were then tested on a yes-no signal detection procedure. The task involved detection of fast moving words among fast moving string of letters. To analyse performance indices for sensory sensitivity and response bias were estimated. Results indicate that high scorers in terms of the UnEx dimension reported more false alarms (hallucinations than low scores. The results are discussed in terms of past findings, and future directions for the study of schizophrenia based on learning-theoretic paradigms.
