Male and female subjects (Ns = 100) performed an accuracy task involving consecutive arm swings at a self-paced tempo. Following this, the subjects performed a motor rhythm task keeping in cadence with audio-visual stimuli presented at their preferred tempo. Previous findings regarding the magnitude of individual differences in preferred tempo and within-individual variability were replicated, as was the absence of sex differences for these attributes. With regard to motor rhythm, the findings indicated that (a) constant and variable error, and not absolute error, were the appropriate measures of performance, (b) there were no sex differences either in spatial or temporal accuracy or in trial-to-trial consistency of performance, (c) substantial individual differences were present in rhythmic accuracy, as were moderate individual differences in variability, (d) neither rhythmic accuracy nor variability was appreciably related to preferred tempo, and (e) spatial and temporal accuracy are relatively independent components of rhythmic accuracy.
男性和女性受试者（各100名）进行了一项准确性任务，任务内容是按照自己选择的节奏连续摆动手臂。在此之后，受试者进行了一项运动节奏任务，与以他们偏好的节奏呈现的视听刺激保持一致。之前关于偏好节奏的个体差异大小以及个体内部变异性的研究结果得到了重复验证，这些属性也不存在性别差异。关于运动节奏，研究结果表明：（a）恒定误差和可变误差而非绝对误差是衡量表现的合适指标；（b）在空间或时间准确性以及表现的逐次试验一致性方面均不存在性别差异；（c）在节奏准确性方面存在显著的个体差异，在变异性方面也存在中等程度的个体差异；（d）节奏准确性和变异性均与偏好节奏没有明显关联；（e）空间准确性和时间准确性是节奏准确性相对独立的组成部分。
