Brief Summary

Based in an embodied approach of cognition, several studies have highlighted a direct link between perception of an object or an emotion and the associated motor responses. This study investigated in patients suffering from bipolar affective disorders whether the perception of emotional words involves an automatic sensorimotor simulation of approach and avoidance behaviors, and whether the perception of an object involves an automatic sensorimotor simulation of object prehension (affordance). We hypothesize that, in this pathology, low level (sensorimotor) cognitive processes are preserved whereas high-level (attentional) are altered. 20 patients suffering from bipolar affective disorders and 20 healthy controls will be recruited. The main objective is the emergence of sensorimotor compatibility effects in approach-avoidance task with emotional stimuli (gain between compatible vs incompatible conditions).
