The effects of the use of reduced feedback frequencies on motor learning remain controversial in the scientific literature. At present, there is still controversy about the guidance hypothesis, with some works supporting it and others contradicting it. To shed light on this topic, an experiment was conducted with four groups, each with different feedback frequencies (0%, 33%, 67%, and 100%), which were evaluated three times (pre-test, post-test, and retention) during a postural control task. In addition, we tested whether there was a transfer in performance to another similar task involving postural control. As a result, only the 67% feedback group showed an improvement in their task performance in the post-test and retention evaluations. Nevertheless, neither group showed differences in motor transfer performance compared to another postural control task. In conclusion, the findings of this paper corroborate the hypothesis of guidance and suggest that the use of a reduced frequency of 67% is a better option for improving motor learning than options that offer feedback at a lower frequency, at all trials or not at all.
在科学文献中，使用降低反馈频率对运动学习的影响仍存在争议。目前，关于指导假说仍存在争议，一些研究支持该假说，而另一些则与之矛盾。为了阐明这一主题，进行了一项实验，分为四组，每组具有不同的反馈频率（0%、33%、67%和100%），在姿势控制任务期间进行了三次评估（预测试、后测试和保持测试）。此外，我们测试了在涉及姿势控制的另一项类似任务中，表现是否会发生迁移。结果，只有67%反馈组在后测试和保持测试评估中任务表现有所改善。然而，与另一项姿势控制任务相比，两组在运动迁移表现上均未显示出差异。总之，本文的研究结果证实了指导假说，并表明在所有试验中，使用67%的降低频率比完全不提供反馈或提供更低频率反馈的选项更有利于改善运动学习。
