Pavlovian Conditioned Hallucinations Tasks and Psychometric Thresholding in an Enriched Online Sample
BIOLOGICAL PSYCHIATRY(2020)
摘要
Mathematical models based in Bayesian statistics and predictive coding describe perception as a combination of prior beliefs with sensory evidence. Using a Pavlovian auditory conditioned hallucinations (ACH) task, it has been shown that hallucinations are a result of over-weighting of prior beliefs over incoming sensory evidence. Susceptibility to conditioned hallucinations (CH) depended on presence of audio-verbal hallucinations, regardless of diagnosis of psychosis.
