The aim of the present study was to investigate the relationship between finger counting and numerical processing in 4-7-year-old children. Children were assessed on a variety of numerical tasks and we examined the correlations between their rates of success and their frequency of finger use in a counting task. We showed that children's performance on finger pattern comparison and identification tasks did not correlate with the frequency of finger use. However, this last variable correlated with the percentages of correct responses in an enumeration task (i.e., Give-N task), even when the age of children was entered as a covariate in the analysis. Despite this correlation, we showed that some children who never used their fingers in the counting task were able to perform optimally in the enumeration task. Overall, our results support the conclusion that finger counting is useful but not necessary to develop accurate symbolic numerical skills. Moreover, our results suggest that the use of fingers in a counting task is related to the ability of children in a dynamic enumeration task but not to static tasks involving recognition or comparison of finger patterns. Therefore, it could be that the link between fingers and numbers remain circumscribed to counting tasks and do not extent to static finger montring situations.
本研究旨在探讨 4-7 岁儿童的手指计数与数字加工之间的关系。研究人员对儿童进行了各种数字任务的评估,并考察了他们在计数任务中手指使用频率与成功次数之间的相关性。研究结果表明,儿童在手指模式比较和识别任务中的表现与手指使用频率无关。然而,这一变量与枚举任务(即“Give-N”任务)中正确反应的百分比相关,即使在分析中以儿童年龄作为协变量。尽管存在这种相关性,但我们发现一些在计数任务中从未使用手指的儿童在枚举任务中能够表现出色。总的来说,我们的研究结果支持这样的结论,即手指计数虽然有用,但对于发展准确的符号数字技能并非必需。此外,我们的研究结果表明,在计数任务中使用手指与儿童在动态枚举任务中的能力有关,而与涉及手指模式识别或比较的静态任务无关。因此,手指与数字之间的联系可能仅限于计数任务,而不会扩展到静态的手指展示情况。
