Balancing Our Perceptions of the Efficacy of Success-Based Feedback Manipulations on Motor Learning

We report two experiments evaluating the impact of success-related feedback on learning of a balance task. In Exp. 1, we studied the influence of lax and conservative outcome feedback, as well as large vs. small improvements in outcome feedback on balance learning. Despite impacts on competency, there were no between-group differences in actual performance or learning. Because no comparative information was provided in Exp. 1, we tested four further groups that either did or did not receive positive or negative comparative feedback (Exp. 2). Although the manipulations influenced competency and arousal, again, there was no impact on balance outcomes. These data cast doubt on the assertions made in the OPTIMAL theory that perceptions of success are moderators of motor learning.We report two experiments evaluating the impact of success-related feedback on learning of a balance task.
