This study compares the effects of ketamine and psilocybin on sensory learning using EEG and computational modeling, finding distinct neural impacts on precision and volatility in auditory mismatch negativity.

This study compares computational models of approach-avoidance biases in suicidal populations using hierarchical Bayesian inference, finding that simpler models with value decay better explain behavior than complex ones.

This study investigates perceptual priors and hallucinations in chronic schizophrenia using a visual statistical learning task, finding comparable prior acquisition but reduced hallucinations in patients.

The paper investigates how autistic and schizotypal traits affect Bayesian visual integration, finding that autistic traits are linked to more accurate sensory processing rather than weaker priors.
