Study on Communication Comprehension in the Schizophrenic Spectrum
Condition: Schizophrenia Simple
MeSH terms: Schizophrenia
Study type: Interventional

Summary: 
      The purpose of the present study is to evaluate the effect of emotional prosody on the
      perception of emotional discourse in the schizophrenic spectrum. The investigators
      hypothesize that participant may use emotional prosody as an emotional cue to understand the
      emotional content of discourse.
    

Detailed description: 
      The integration of ortholinguistic and paralinguistic functions in language, particularly of
      the emotional prosody, is necessary to interact adaptively with others. People in the
      schizophrenic spectrum have social difficulties. Is emotional prosody comprehension altered
      in these people? According to Edwards et al. (2002), there is methodological issues
      concerning the tasks used to answer this question. Investigators built an emotional judgment
      task more adapted to study the perception of emotional prosody in the schizophrenic spectrum
      than the classical paradigm designed to evaluate participants with cerebral injury. The
      investigators have elaborated a material that consists of 140 short sentences (7±2 words)
      with a simple syntactic structure. The verbal content expressed positive, neutral or negative
      emotions. These sentences were announced by four professional actors (two female) with an
      emotional prosody content congruent or inconsistent with the verbal content. Participants
      will have to evaluate the emotional intensity of the recordings on a five points Likert
      scale, from strongly negative to strongly positive. Psychotic experiences of all participants
      will be evaluated too.
