Abstract

International audience; A previous study on ideomotor action control showed that predictable action effects in the agent’s environment influenced how an action is carried out. If participants were required to perform a forceful keypress, they exerted more force when these actions would produce a quiet compared to a loud tone, and this observation suggests that anticipated proprioceptive and auditory action effects are integrated with each other during action planning and control. In light of the typically weak influence of body-related effect found in recent work, we aimed to extend this pattern of results to the intra-modal case of integrating proprioceptive/tactile feedback of a movement and following vibro-tactile effects. Our results suggest that the same weighted integration process as for the cross-modal case applies to the intra-modal case. These observations support the idea of a common mechanism which binds all action-related features in an integrated action representation, irrespective of whether these features relate to exafferent or reafferent signals.
