Trait psychoticism is associated with greater intersubject neural dissimilarity during naturalistic social movie viewing.

ABSTRACT: Psychoticism refers to maladaptive traits associated with eccentricity, perceptual dysregulation, and unusual beliefs. This study explored how individual differences in psychoticism map into neural responses during naturalistic movie-watching. By utilizing social movies with differing demands of inference, we examined how relevant correspondence of individual differences emerges as a function of movie features. A total of 157 individuals were assessed with traits of psychoticism, and intersubject correlation of neural response was assessed with functional near-infrared spectroscopy (fNIRS). Three movie-watching conditions (low-social, high-social A/B) were compared in the examination of brain-trait correspondence. The result showed that the intersubject distance of psychoticism scores corr
