The aim of the study was to assess the ability to maintain a steady pace during a counting task, aloud or silently, when a fast (28 counts every 900 ms) or slow (18 counts every 1,400 ms) pace is adopted (target = 25,200 ms), and to test whether ability is the same for musician and nonmusicians. The study analyzes the mean and variability of 30 temporal productions. The results show more variability (a larger coefficient of variation: standard deviation/mean production) in the condition where the pace is slow, a finding consistent with previous reports with this task. This finding applies here in both the aloud and silent counting conditions and, most importantly, applies to both musicians and nonmusicians. The results also indicate that there is no significant difference for the absolute error (|mean production - target duration|). In brief, the capacity to keep variability low when maintaining a pace seems to gain benefit from musical training, and this training difference does not depend on counting aloud versus silently and is not restricted to brief intervals.
该研究的目的是评估在采用快速（每900毫秒计数28次）或慢速（每1400毫秒计数18次）节奏（目标时长为25200毫秒）时，无论是大声还是默读计数任务中保持稳定节奏的能力，并测试音乐家和非音乐家在这方面的能力是否相同。该研究分析了30次计时结果的平均值和变异性。结果显示，在节奏较慢的情况下变异性更大（变异系数更大：标准差/平均计时结果），这一发现与此前关于该任务的报告一致。这一发现适用于大声和默读计数两种情况，最重要的是，适用于音乐家和非音乐家。结果还表明，绝对误差（|平均计时结果 - 目标时长|）没有显著差异。简而言之，在保持节奏时将变异性维持在较低水平的能力似乎得益于音乐训练，且这种训练差异并不取决于大声还是默读计数，也不限于短时间间隔。
