发展性计算障碍儿童的数认知

Numerical and Arithmetical Cognition in Developmental Dyscalculia

发展性计算障碍作为一种特异性学习障碍，影响儿童的数学成就与数学学习观念，因而引起了多学科研究的关注和重视。文章分析了发展性计算障碍领域在数认知方面的已有研究，揭示了发展性计算障碍的数认知缺陷及内部差异，从一般认知加工障碍与数学加工模块障碍两个角度阐述了发展性计算障碍的可能成因，最后对当前研究进行了小结与展望，认为数认知缺陷的复杂关系、亚类型特征、成因之间的相互作用与机制还需进一歩研究。

Developmental dyscalculia（DD）， as a specific type of learning disabilities， has pervasive effects on children’s mathematical achievement and perception of mathematical learning. It has become a focus of many research disciplines during recent years. This article reviewed current progress in numerical and arithmetical cognition id DD， explored some issues as followed， the performance and characteristics of numerical and arithmetical cognition in DD， the cognition performance of subtypes， general cognition deficit and numerical processing module deficit as possible causes for DD. It’s suggested future research topics are to examine the complicated relationships between different numerical and arithmetical cognitive deficits， the characteristics of subtypes， and the interactions and mechanisms between possible causes.
