Impaired Motion Processing in Schizophrenia and the Attenuated Psychosis Syndrome: Etiological and Clinical Implications

What is it about?

The ability to perceive the motion of biological objects, such as human faces, is a critical component of daily function and correlates with the ability to successfully navigate social situations ("social cognition"). The authors examined the neural bases of impaired visual and motion processing in schizophrenia and attenuated psychosis (clinical high risk) patients and its relationship to social cognitive deficits in these populations. The findings of the study emphasize the importance of sensory-level visual dysfunction in the etiology and personal experience of individuals with schizophrenia, and demonstrates that motion processing deficits may predate illness onset and contribute to impaired function even in clinical high risk, attenuated psychosis patients.
