| 摘 要： | 选取113名小学二年级儿童为被试,探讨了工作记忆广度对儿童算术认知策略的影响。结果表明:不同工作记忆广度儿童在出声、手动、心里数数、竖式、分解、凑整、猜测和放弃策略的选择频次上具有显著差异,在算术认知策略的执行上,差异明显;随着工作记忆广度的增加,出声策略表现出了波动型的变化曲线,手动、心里数数、凑整和猜测策略具有门槛型的变化趋势,竖式、分解和放弃策略呈现出阶梯状的变化特点。这些结果说明,儿童算术认知策略表现受到其工作记忆容量明显的限制性作用。

| Abstract: | The influence of working memory span on children's arithmetical strategies was examined in a sample of 113 primary school children in grade 2.The results indicated that the strategies selection of children with different span had significant difference.These strategies included speaking-aloud,hand-moving,count-in-mind,vertical-formula,decomposition,make-up-the-number,guessing and quit.The execution of the strategies of different span children was also distinct.When the span was aligned from the lowest to the highest,selection of speaking-aloud strategy showed a shape of wave,and the hand-moving,count-in-mind and guess indicated threshold trends,and the vertical-formula,decomposition and quit had the traits of ladder.Chiefly,the performances of children's arithmetical cognitive strategies were obviously limited to their working memory capacity. |
