据报道,精细运动技能(FMS)和手指失认症的方面可以预测幼儿的数字能力,可能会影响早期的手指计数体验。此外,涉及手指运动运动的区域之间的神经元连接,手指失认症,并提出了数值处理。在这项研究中,研究了FMS和手指失认症作为学龄前儿童在数字任务中表现的预测因子。学龄前儿童(N=153)完成了测量手指敏捷性和手指灵活性的FMS任务以及非运动性手指失认症任务。此外,儿童完成了涉及手指使用的数字任务(即,手指计数和手指步进),和没有的任务(即,图片辅助计算和数字线估计)。为了控制领域通用技能可能的混杂影响,我们包括推理和空间工作记忆的测量。我们发现FMS与手指计数和计算之间存在关联,但不是指头。相比之下,手指失认症只与手指跳动有关,但不是手指计数和计算。令人惊讶的是,FMS或手指失认症与数线估计之间没有关联.研究结果强调了手指失认症之间的关系,FMS,和数字技能是特定于任务要求。讨论了可能的影响。
Facets of fine motor skills (FMS) and finger gnosia have been reported to predict young children\'s numerical competencies, possibly by affecting early finger counting experiences. Furthermore, neuronal connections between areas involved in finger motor movement, finger gnosia, and numerical processing have been posited. In this study, FMS and finger gnosia were investigated as predictors for preschool children\'s performance in numerical tasks. Preschool children (N = 153) completed FMS tasks measuring finger agility and finger dexterity as well as a non-motor finger gnosia task. Furthermore, children completed numerical tasks that involved finger use (i.e., finger counting and finger montring), and tasks that did not (i.e., picture-aided calculation and number line estimation). To control for possible confounding influences of domain general skills, we included measures of reasoning and spatial working memory. We found associations between FMS and both finger counting and calculation, but not finger montring. In contrast, finger gnosia was only associated with finger montring, but not finger counting and calculation. Surprisingly, there were no associations between FMS or finger gnosia with number line estimation. Findings highlight that the relationship between finger gnosia, FMS, and numerical skills is specific to task requirements. Possible implications are discussed.
