The authors examined several issues related to the motor learning benefits resulting from giving learners choices. In 2 experiments, participants practiced a novel task, throwing a lasso. In Experiment 1, giving learners a choice ostensibly irrelevant to performance (color of mat under target) resulted in enhanced learning relative to a control group. The choice group also reported more positive affect. Experiment 2 compared the effectiveness of task-irrelevant (mat color) versus task-relevant (video demonstrations of the skill) choices. In both choice groups, each participant was yoked to a participant in the other group, and each received the same mat color or saw the video demonstration, respectively, as chosen by their counterpart in the other group. In the control group, participants were yoked to their respective counterparts in each of the choice groups. On a retention test, the 2 choice groups did not differ from each other, but both outperformed the control group. The affective and learning effects seen when learners are given choices, and the fact that task-relevant and task-irrelevant choices resulted in similar learning benefits, are consistent with a content-neutral mechanism for the effects of choice on learning, as described in the OPTIMAL theory of motor learning (Wulf & Lewthwaite, 2016 ).
作者研究了与给予学习者选择所带来的运动学习益处相关的几个问题。在两项实验中,参与者练习了一项新任务——扔套索。在实验1中,给予学习者一个表面上与表现无关的选择(目标下方垫子的颜色),相对于对照组,学习效果得到了增强。选择组也报告了更积极的情绪。实验2比较了与任务无关(垫子颜色)和与任务相关(技能的视频演示)的选择的有效性。在两个选择组中,每个参与者都与另一组中的一名参与者配对,并且分别收到与其在另一组中的对应者选择的相同的垫子颜色或观看相同的视频演示。在对照组中,参与者与每个选择组中的各自对应者配对。在一项留存测试中,两个选择组之间没有差异,但都优于对照组。当给予学习者选择时所看到的情感和学习效果,以及与任务相关和与任务无关的选择产生相似学习益处这一事实,与运动学习的OPTIMAL理论(伍尔夫和卢思韦特,2016)中所描述的选择对学习影响的内容中立机制是一致的。
