Why people with schizophrenia may have trouble reading social cues

From Abstract of: Perception of Biological Motion in Schizophrenia and Healthy Individuals: A Behavioral and fMRI Study (PLoS One)

Anomalous visual perception is a common feature of schizophrenia plausibly associated with impaired social cognition that, in turn, could affect social behavior. Past research suggests impairment in biological motion perception in schizophrenia. Behavioral and functional magnetic resonance imaging (fMRI) experiments were conducted to verify the existence of this impairment, to clarify its perceptual basis, and to identify accompanying neural concomitants of those deficits.
