Cross-Modality Evidence for Reduced Choice History Biases in Psychosis-Prone Individuals.

ABSTRACT:

Objectives

Predictive processing posits that perception emerges from inferential processes within a hierarchical cortical system. Alterations of these processes may result in psychotic experiences, such as hallucinations and delusions. Central to the predictive processing account of psychosis is the notion of aberrant weights attributed to prior information and sensory input. Based on the notion that previous perceptual choices represent a relevant source of prior information, we here asked whether the propensity towards psychotic experiences may be related to altered choice history biases in perceptual decision-making.

Methods

We investigated the relationship between choice history biases in perceptual decision-making and psychosis proneness in the general population. Choic
