Interactions between Perception and Action

 

Interactions between Perception and Action

Sage 4101

While it is clear that the motor system is guided by visual information about both the body and the target, surprisingly little research addresses how visual perception may be influenced by information provided by the motor system. This disparity exists despite the fact that neural pathways leading from visual areas to motor areas are mirrored by pathways from motor areas to visual areas (e. g. Wise et al., 1997). I will present two studies thatshow the motor system influencing the visual system. One study focuses on how the motor system adapts to forces in the environment, and asks if force information acquired during adaptation influences how we perceive and intercept accelerating targets. Another study focuses on how visual attention and perception are linked to the hand. In particular, this study shows that hand position influences residual vision in patients who are partially blind. Together, these studies reveal an interdependence between the motor and visual systems that deserves further examination.
