Abstract: Individuals diagnosed with schizophrenia spectrum disorders (SSD) exhibit a constellation of sensory and perceptual impairments, including hyporeactivity to external input. However, individuals with SSD also report subjective experiences of sensory flooding, suggesting sensory hyperexcitability. To identify the extent to which behavioural indices of hyperexcitability are related to non‐psychotic symptoms of schizophrenia, we tested a non‐clinical population measured for schizophrenia‐like traits (schizotypy), and a behavioural measure of sensory hyperexcitability, specifically the number of illusions seen in the Pattern Glare Test. Two samples totaling 913 individuals completed an online version of the Schizotypal Personality Questionnaire – Brief Revised (SPQ‐BR) and the Pattern Glare Test. Individuals with higher schizotypy traits reported more illusions in the Pattern Glare Test. Additionally, one of the three SPQ‐BR factors, the disorganized factor, significantly predicted the number of illusions reported. These data illustrate the potential for research in non‐clinical samples to inform clinically relevant research. [ABSTRACT FROM AUTHOR]
