Effect of prior body experience on adaptation to visual displacement

The effect of proprioceptive adaptation to visual displacement is to produce a violation of the normal constraints on the relative position of body parts. In order to investigate the effect of this violation of constraints on the adaptation, the relative position of body parts for a group of dancers and a group of nondancers was determined after 5 and 15 min of adaptation. Empirical and theoretical support were provided for the propositions that (1) there is a tendency to resist the violation of constraints, and (2) the nature of the adaptation process is such as to minimize the amount of violation of constraints.
