In an experiment concerned with adaptation of the hand to lateral displacement no significant differences between active and passive exposure were found. With one of the dependent variables increasing temporal delays following exposure were associated with decreasing adaptation. However, using a second dependent variable, data suggested the unexpected result that an intermediate amount of delay was associated with maximum adaptation. Also suggested by the data for one measure was the unpredicted result that relatively long exposure durations produced adaptation that dissipated more rapidly at first than adaptation produced by briefer exposures.
