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.
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.

|---|---|---|
| Behavioural measures (response rate and time) | Participants will have to judge the emotional intensity of audio recordings. In this task, the participant is asked to judge the emotional intensity of audio recordings of men and women (2 actors + 2 actresses): he / she must press a button as quickly as possible to indicate whether the Audio recordings presented via small speakers are very negative, negative, non-emotional, positive or very positive (5 possible choices). The response time variable may be added as a co-variable in order to avoid perceptive-motor disorders (medication-related and / or general motor slowdown) that may influence the results of time-of- answers. | During the experiment |
| Measure | Description | Time Frame |
|---|---|---|
| Symptomatic impact | Evaluate the nature of the psychotic experiments (CAPE-42 test). | During the experiment |
| Evaluate the cognitive functioning | Neuropsychological tests will allow evaluating the cognitive profile of the participants that can impact their behaviour during the experiment. |

|
| Detection task | Behavioral | Participants indicate every time they heard a given sound in order to verify their audition level. |
|
| CAPE-42 | Other | This questionnaire allows evaluating the nature of psychotic experiences. |
