Abstract

Music and metronomes differentially impact movement performance. The current experiment presented metronome and drum beats in simple and complex rhythms before goal-directed reaching movements, while also quantifying enjoyment. Auditory conditions were completed with and without visual feedback and were blocked and counterbalanced. There were no differences between simple and complex rhythms, indicating that rhythmic information alone is sufficient to benefit performance. The drum elicited shorter movement times and higher peak velocities, without an increase in spatial variability. Reaction times were moderately correlated with ratings of enjoyment. These data provide evidence that the source of an auditory stimulus impacts movement performance of a goal-directed reaching task. Results are contextualized within models of goal-directed reaching to elucidate mechanisms contributing to performance improvements.

摘要

音乐和节拍器对运动表现的影响不同。当前的实验在目标导向的到达动作之前以简单和复杂的节奏呈现节拍器和鼓的节拍，同时还量化了享受。听觉条件在有和没有视觉反馈的情况下完成，并被阻止和平衡。简单节奏和复杂节奏之间没有差异，这表明单独的节奏信息足以使表现受益。鼓引起了更短的运动时间和更高的峰值速度，而没有增加空间可变性。反应时间与享受程度呈中度相关。这些数据提供了证据，表明听觉刺激的来源会影响目标导向的到达任务的运动表现。
