Association Between Failures in Perceptual Updating and the Severity of Psychosis in Schizophrenia

# Association Between Failures in Perceptual Updating and the Severity of Psychosis in Schizophrenia

Quote:

In this case-control study of 160 participants in 2 independent samples, perceptual updating was assessed via a random dot motion perception task in which motion direction changes midway through a trial, and participants were asked to report the direction at the end of the trial. Individuals with schizophrenia tended to overreport the direction of the initial motion rather than the changed motion direction as instructed, which was associated with the severity of delusions and hallucinations.
