针对敲击间隔及其组成部分（每次敲击的按键按下和按键释放阶段）评估了快速敲击的速率和变异性方面的手部差异。为了强调潜在的手部差异，仅包括一只手具有明显手动优势的受试者。 Fitts 相互敲击任务的相对手动熟练程度用于排除具有不太明确的手优势或优势的个体，并将受试者分类为具有优势左手（n = 13）或右手（n = 11）。方差分析表明优势手的平均敲击间隔较短，因此敲击速度较快。发现这种手部速率差异对于敲击的按键按下阶段非常显着，但对于按键释放阶段则不显着。在每个惯用手组中，惯用手在敲击间隔和两个成分方面表现出较小的变异性。讨论了这些发现与顺序能力半球不对称的潜在关联。
Hand differences in the rate and variability of rapid tapping were evaluated for the intertap interval and its constituents-the key depression and key release phases of each tap. To accentuate potential hand differences, only subjects with a clear manual superiority in one hand were included. Relative manual proficiency on Fitts' reciprocal tapping task was used to exclude individuals with less-defined hand superiority or dominance, and to categorize subjects as having a dominant left (n=13) or right (n=11) hand. Analysis of variance indicated the dominant hand to have a shorter average intertap interval and thus a faster tapping rate. This hand difference in rate was found to be significant for the key-depression phase, but not the key-release.phase, of the tap. In each handedness group the dominant hand exhibited less variability in the intertap interval and both constituents. Potential associations of these findings with hemispheric asymmetries in sequential ability are discussed.
