通过对127名儿童的纵向研究，考察了工作记忆在儿童数学问题解决中的作用。对一年级儿童的问题解决、成绩、工作记忆和认知加工(抑制、速度、语音编码)进行了一系列测试，并对二年级和三年级进行了跟踪测试。结果表明：(A)对三年级词汇问题解决成绩有唯一影响的一年级预测因子是工作记忆、命名速度和抑制；(B)工作记忆执行成分的增长与词汇问题解决准确度的增长显著相关。研究结果支持工作记忆执行系统的发展是儿童问题解决能力发展的重要预测因素，而不是注意力不集中、抑制、加工速度等认知指标以及与计算和阅读相关的成就指标的影响。
The role of working memory (WM) in children's growth in mathematical problem solving was examined in a longitudinal study of children (N = 127). A battery of tests was administered that assessed problem solving, achievement, WM, and cognitive processing (inhibition, speed, phonological coding) in Grade 1 children, with follow-up testing in Grades 2 and 3. The results were that (a) Grade 1 predictors that contributed unique variance to Grade 3 word problem-solving performance were WM, naming speed, and inhibition and (b) growth in the executive component of WM was significantly related to growth in word problem-solving accuracy. The results support the notion that growth in the executive system of WM is an important predictor of growth in children's problem solving beyond the contribution of cognitive measures of inattention, inhibition, and processing speed as well as achievement measures related to calculation and reading.
