Recent studies examining the role of self-controlled feedback have shown that learners ask for feedback after what they believe was a "good" rather than "poor" trial. Also, trials on which participants request feedback are often more accurate than those without feedback. The present study examined whether manipulating participants' perception of "good" performance would have differential effects on learning. All participants practiced a coincident-anticipation timing task with a self-controlled feedback schedule during practice. Specifically, they were able to ask for feedback after 3 trials in each of three 10-trial practice blocks. While one group (Self-30) was told that an error of 30 ms or less would be considered good performance, another group (Self-4) was informed that an error of 4 ms or less would be considered a good trial. A third, self-control group (Self) did not receive any information about what constituted good performance. The results showed that participants of all groups asked for feedback primarily after relatively good trials. At the end of practice, both the Self-30 and Self groups demonstrated greater perceived competence and self-efficacy than the Self-4 group. The Self-30 and Self groups also performed with greater accuracy and less variability in retention and transfer (non-dominant hand) 1 day later. The present findings indicated that the typical learning benefits of self-controlled practice can be thwarted by depriving learners of the opportunity of experiencing competence through good performance. They add to the accumulating evidence of motivational influences on motor learning.
最近的研究考察了自我控制反馈的作用,表明学习者在他们认为是“好”而不是“差”的尝试之后要求反馈。此外,参与者请求反馈的尝试往往比没有反馈的尝试更准确。本研究考察了操纵参与者对“良好”表现的看法是否会对学习产生不同的影响。所有参与者在练习期间都使用自我控制反馈计划练习同时预期时间任务。具体来说,他们可以在每个 10 次练习块中的 3 次试验后要求反馈。当一组(Self-30)被告知 30 毫秒或以下的误差将被视为良好表现时,另一组(Self-4)则被告知 4 毫秒或以下的误差将被视为良好试验。第三组,自我控制组(Self)没有收到任何关于良好表现的信息。结果表明,所有组的参与者主要在相对较好的试验后要求反馈。在练习结束时,Self-30 组和 Self 组都表现出比 Self-4 组更高的感知能力和自我效能感。Self-30 组和 Self 组在保留和转移(非主导手)1 天后的表现也更准确,变异性更小。本研究结果表明,剥夺学习者通过良好表现体验能力的机会,可能会破坏自我控制练习的典型学习益处。它们增加了动机对运动学习影响的累积证据。
