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 (Fuchs, 2005). 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 actions potentially associated (Gibson (1977, 1979) explored by Stimulus Response Compatibility (SRC) paradigm. The existence of visual motor neurons leads us to postulate that the affordance effect can be assisted by a visuomotor priming of a hand in a position to grasp. With Tucker \& Ellis sensory motor compatibility task, we study the capacity of affordance in schizophrenia, as well as the impact of perceptual motor priming on these affordance effects.
