Previous studies investigating the association between fine-motor skills (FMS) and mathematical skills have lacked specificity. In this study, we test whether an FMS link to numerical skills is due to the involvement of finger representations in early mathematics. We gave 81 pre-schoolers (mean age of 4 years, 9 months) a set of FMS measures and numerical tasks with and without a specific finger focus. Additionally, we used receptive vocabulary and chronological age as control measures. FMS linked more closely to finger-based than to nonfinger-based numerical skills even after accounting for the control variables. Moreover, the relationship between FMS and numerical skill was entirely mediated by finger-based numerical skills. We concluded that FMS are closely related to early numerical skill development through finger-based numerical counting that aids the acquisition of mathematical mental representations.
以往关于精细运动技能（FMS）与数学技能之间关联的研究缺乏特异性。在本研究中，我们测试FMS与数字技能之间的联系是否源于早期数学中手指表征的参与。我们对81名学龄前儿童（平均年龄4岁9个月）进行了一系列FMS测量以及有和没有特定手指关注的数字任务。此外，我们使用接受性词汇和实际年龄作为控制变量。即使在考虑了控制变量之后，FMS与基于手指的数字技能的联系比与非基于手指的数字技能的联系更为紧密。此外，FMS与数字技能之间的关系完全由基于手指的数字技能介导。我们得出结论，FMS通过基于手指的数字计数与早期数字技能发展密切相关，这种计数有助于数学心理表征的习得。
