The influence of a secondary task and type of feedback on adaptation to lateral displacement of the visual array

This experiment was designed to investigate the influence of a secondary attention-demanding force-production task on adaptation to prismatic displacement. Recent suggestions by Finke (1979) lead to the prediction that a secondary task executed during adaptation would interfere with the central component of adaptation (as measured by intermanual transfer), but not the peripheral component (adaptation specific to adapted limb). There were three …
