Relearning movements: modification of an incorrectly timed reversal movement.
The main purpose of this study was to examine if an inaccurately acquired motor response can be relearned through the provision of a limited number of correct KR trials. 26 subjects were assigned to one of three experimental groups: a no-KR group, an erroneous KR group, and a relearning group who were given correct KR after 125 trials of erroneous KR. Analysis showed a significant temporal correction of the reversal movement when the erroneous KR was replaced by valid verbal information during acquisition. This adaptation, however, was attenuated during retention, indicating that the limited number of correct KR trials did not wash out the effect of the invalid information provided during the first phase of acquisition.
