title: Do you see what I feel?--Electrophysiological correlates of emotional face and body perception in schizophrenia.
abstract: OBJECTIVE
  We aimed to elucidate whether impaired affective face processing--behaviourally and with regard to P100 and N170 components--is paralleled by similar deficits in body processing in schizophrenia. Furthermore, we aimed to assess modulations by the processing of emotional or personal identity of the stimuli.
  
  
  METHODS
  Fourteen patients with schizophrenia and 15 healthy controls were assessed with a Delayed Matching-to-Sample Task involving variations of the emotional (same vs. different valence) and personal identity (same vs. different person) of bodies and faces.
  
  
  RESULTS
  Patients showed overall poorer behavioural performance. In controls, P100 amplitudes were enhanced in the "same identity/different emotions" vs. "same identity/same emotion" condition and N170 amplitudes were larger for different vs. same emotions. In the patients, P100 amplitudes were enhanced in the right relative to the left hemisphere for faces, but not for bodies.
  
  
  CONCLUSIONS
  Patients with schizophrenia show deficient modulation of the P100 and N170 components by emotional and personal identity of faces and bodies, which may relate to deficient context processing.
  
  
  CONCLUSIONS
  Our findings suggest for the first time alterations of the electrophysiological correlates of body processing in schizophrenia.
