‘Cognitive inhibition’ and schizotypy as measured by the Oxford-Liverpool inventory of feelings and experiences

Previous studies have reliably shown a reduced level of the negative priming effect in both schizophrenics and high schizotypes. Measurement of symptom orientated aspects of schizotypy has previously utilised lengthy questionnaires such as the CSTQ, or individual use of several different questionnaires. We attempted to replicate previous findings with use of the OLIFE, a relatively short schizotypy questionnaire derived from the CSTQ. Consistent with recent research, reduced negative priming was significantly linked with subjects scoring high on scales related to positive, and not negative, aspects of schizophrenic symptomatology, whilst the Stroop effect was found to be independent of all measures of schizotypy. The OLIFE served as a useful tool, allowing examination of specific aspects of schizotypy within the time pressures of a laboratory environment.
