Motion Speed Processing Abnormalities Not Found in Schizophrenia

Key clinical point: Schizophrenia patients show no deficits in motion speed processing, compared with healthy controls.

Major finding: Researchers measured speed processing using the Flash Lag illusion; patients and controls showed a linear increase with increasing speed, and no interaction between speed and group (P = 0.496).

Study details: The data come from 18 outpatients diagnosed with schizophrenia and 21 matched healthy controls.

Disclosures: The study was supported by the Alexander von Humboldt Foundation, the Australian Research Council Centre of Excellence in Cognition and its Disorders, and the Swiss National Science Foundation. The researchers had no financial conflicts to disclose.
