工作记忆的三个核心组成部分对幼儿数学技能发展的贡献知之甚少。具体WM组件和数值运算，强调计算和事实检索，和数学推理，强调口头问题解决能力在48个第二和50个第三年级学生之间的关系进行了评估，使用标准化WM和数学成绩的措施。对于二年级学生，中央执行和语音组件预测数学推理技能，而视觉空间组件预测数学推理和数值运算技能在三年级学生。这种模式表明，中央执行和语音回路促进性能在早期阶段的数学学习，而视觉空间表征在后期阶段发挥越来越重要的作用。我们认为，这些变化反映了从前额叶顶叶皮层功能在数学技能的收购。学习和个体差异的影响进行了讨论。
The contribution of the three core components of working memory (WM) to the development of mathematical skills in young children is poorly understood. The relation between specific WM components and Numerical Operations, which emphasize computation and fact retrieval, and Mathematical Reasoning, which emphasizes verbal problem solving abilities in 48 2nd and 50 3rd graders was assessed using standardized WM and mathematical achievement measures. For 2nd graders, the central executive and phonological components predicted Mathematical Reasoning skills; whereas the visuo-spatial component predicted both Mathematical Reasoning and Numerical Operations skills in 3rd graders. This pattern suggests that the central executive and phonological loop facilitate performance during early stages of mathematical learning whereas visuo-spatial representations play an increasingly important role during later stages. We propose that these changes reflect a shift from prefrontal to parietal cortical functions during mathematical skill acquisition. Implications for learning and individual differences are discussed.
