数学能力的改善：针对工作记忆训练的元分析 postprint

Abstract: Working memory training can effectively improve individual’s cognitive performance. In last decades, accumulating studies examined the transfer effects of working memory training on the mathematical abilities. However, findings from these studies render inconsistent depending on the measure of mathematical abilities, types of working memory training, and participants. In this meta-analysis, we thus reviewed two types of trainings strategies-uni-dimensional and multi-dimensional trainings - and their effects on the enhancement of mathematical skills, including number sense, arithmetic and mathematics reasoning. Results showed that working memory training significantly improved number sense with a medium effect size (Cohen’s d = 0.51), rather than arithmetic (Cohen’s d = 0.04) and mathematics reasoning (Cohen’s d = -0.06). Furthermore, the types of working memory training significantly moderated the transfer effects of working memory training on mathematical performance.
