Psychotic-like experiences may reflect disrupted signal discrimination, whereby individuals overinterpret noisy sensory input as meaningful. Drawing on predictive coding accounts, we investigated whether increased sensory precision and reduced data-gathering relate to psychotic-like experiences in a signal discrimination task. We fitted drift-diffusion models to Random Dot Motion (RDM) task...
