Reduced weighting of short-term perceptual priors during auditory perceptual decision-making in psychosis-prone individuals.

ABSTRACT:

Background

Serial dependencies in perceptual tasks have been suggested to reflect implicit perceptual priors derived from short-term perceptual history. A reduced weighting of perceptual priors has been proposed as a mechanism underlying psychotic experiences such as delusions and hallucinations. Here, we sought to characterize the effects of implicit and explicit perceptual priors on auditory perceptual decision-making and their modulation by psychosis proneness.

Results

Across two online experiments, 197 healthy participants completed an auditory two-alternative forced-choice task and standard questionnaires assessing psychosis proneness. In experiment 1, we assessed serial dependence by quantifying the influence of previous on current perceptual choices. Participants reve
