Switching between tasks during practice can affect motor learning. This study tested whether switching feedback content has any effects on learning to perform golf putts without full visibility. 60 participants (44 men, 16 women; M age = 26.3 yr., SD = 6.6) practiced golf putts without seeing the ball movement. 30 of the participants were golfers with moderate expertise, and 30 were novices. They received feedback regarding their putts, either on the angle or on the distance in one of three feedback schedules: blocked, serial-blocked, or serial. Independent of the expertise level, learning was not affected by the feedback schedule. The strong linkage between the two components--direction and distance--may have prevented a sufficient level of contextual interference.
在练习过程中切换任务会影响运动学习。本研究测试了在不完全可见的情况下，切换反馈内容是否会对学习高尔夫推杆产生影响。60 名参与者（44 名男性，16 名女性；M 年龄=26.3 岁，SD=6.6）在看不见球的情况下练习高尔夫推杆。其中 30 名参与者是具有中等专业知识的高尔夫球手，30 名是新手。他们收到了关于他们推杆的反馈，要么是关于角度，要么是关于距离，反馈计划有三种：封闭的、序列封闭的或序列的。独立于专业水平，学习不受反馈计划的影响。两个组件——方向和距离之间的紧密联系可能阻止了足够水平的情境干扰。
