Summary

Brief Summary: In schizophrenia, dislocation of psychic functions involving a loss of contact with reality is frequently found. A fragmentation of motor and sensory perceptions could be held responsible. However, automatic integration between perception and action is the necessary condition to be in "relationship with the world." Affordance is the experimental link between object perception and potentially associated actions (Gibson, 1977, 1979) explored by Stimulus Response Compatibility (SRC) paradigm. With Tucker \& Ellis sensory motor compatibility task (1998), with a modified response device (responses given with grasp), we study the impact of motor activation on these affordance effects. In this study, a group of controls will also be included in order to understand, as precisely as possible, the mechanisms involved (i.e., interference between the perception of the object and the response gesture).

Interventions

OTHER

cognitive tasks + PANSS+ IQ

Patients will perform different tasks: reaction time (Alert TEA, Zimmermann and Fimm, 2005), Edinburgh laterality questionnaire (Oldfield,1971), IQ test (IQ: PM38, Raven, 1960), and the PANSS (Positive and Negative Syndrome Scale (Kay et al., 1987) + the experimental task (affordance task with graspable device)

OTHER

cognitive tasks

Healthy volunteers will perform only Edinburgh laterality questionnaire (Oldfield, 1971) + the experimental task (affordance task with graspable device).
