Motion as input: a functional explanation of movement effects on cognitive processes.
Motion is often thought of as the result of perceptual and higher cognitive processes. Although this idea has been investigated in myriad ways, the understanding of how movements tune cognitive processes is still in its infancy. The present study examined the nonaffective tuning of movements (arm extension and arm flexion) on heuristic and systematic processes. In a departure from recent cognitive tuning models, a model was derived that defines the tuning effect based on the movement goal and not on the movement position. In the experiment, participants moved toward an extension or flexion position with a movement goal which connected the movement with either an avoidance or an approach function. Analysis indicated that cognitive tuning is a product of the movement goal rather than the movement position. Implications for models of motor control as well as for cognitive tuning models are presented.
