Signal discrimination in the psychotic phenotype: increased sensory precision and reduced decision threshold associated with psychotic-like experiences.

Cognitive neuropsychiatry - 1 Jul 2025

Scaramozzino Francesco, McKay Ryan, Furl Nicholas

Abstract excerpt

BACKGROUND: 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. METHODS: We fitted drift-diffusion models to Random Dot Motion (RDM) task...
