Abstract

An interesting set of findings has emerged from the literature regarding schizotypy. Individuals with psychometric schizotypy self-report pathology in certain neuropsychological concerns, affective experiences, expressive/communicative, olfactory experience abilities and subjective quality of life generally at levels between one and two standard deviations more severe than their non-schizotypal peers; a level often similar to that seen in chronic schizophrenia. Objectively however, individuals with psychometric schizotypy do not show concomitant impairments in these domains. This dysjunction is remarkable in that samples are largely drawn from college settings; thus likely reflecting the healthiest individuals within the schizophrenia-spectrum. We propose that this dysjunction can be conceptualized as a “cognitive bias”, and that it reflects a dysfunction in the systems underlying appraisal, self-evaluation and/or self-reporting processes. In this article, we lay out evidence underlying the subjective-objective dysjunction and discuss potential methodological and psychological issues that may explain this phenomenon.
