本研究探讨动机和增强反馈处理是否解释了运动学习的偶然选择的效果，并检查动机和反馈处理是否普遍预测学习。因此，参与者被分配到两组中的一组，选择或轭，然后要求练习非优势臂投掷豆袋。选择组被允许选择他们投掷的豆袋的颜色，而轭组则没有。运动技能的学习通过延迟后测的准确性和精确性来确定。动机和增强反馈处理分别通过内在动机量表和脑电图进行索引。我们预测选择组将表现出更大的运动学习，动机和增强反馈处理，后两个变量将预测学习。结果表明，一个偶然的选择未能提高运动学习，动机，或增强反馈处理。此外，无论是...
The present study investigated whether motivation and augmented feedback processing explain the effect of an incidental choice on motor learning, and examined whether motivation and feedback processing generally predict learning. Accordingly, participants were assigned to one of two groups, choice or yoked, then asked to practice a nondominant arm beanbag toss. The choice group was allowed to choose the color of the beanbag with which they made the toss, whereas the yoked group was not. Motor learning was determined by delayed-posttest accuracy and precision. Motivation and augmented feedback processing were indexed via the Intrinsic Motivation Inventory and electroencephalography, respectively. We predicted the choice group would exhibit greater motor learning, motivation, and augmented feedback processing, and that the latter two variables would predict learning. Results showed that an incidental choice failed to enhance motor learning, motivation, or augmented feedback processing. In addition, neither ...
