Multisensory relationships between perception and action

Sensory-motor transformation is crucial for self-movement in the environment because it provides the rules for transforming the sensory coordinates of a particular object into the motor coordinates appropriate for guiding action toward that object. It appears logical to think that the sensory coordinates of the object would guide the perception of that object, however well-established ties between perception and action suggest that action also plays a role in the way an object is perceived. The question arises as to what object representation guides perception: the sensory coordinates of the object alone or the motor coordinates as well? To investigate this issue, perception must be probed both before and after a spatial discrepancy between sensory and motor coordinates has been introduced. Such a dissociation is made possible by mechanisms of plasticity and tool use. The present proposal adopts these two methods in behavioral and EEG investigations of healthy human adults to examine the role that motor coordinates might play in the organization of visual, auditory and tactile perception.
