摘　　要：近年来,对于发展性计算障碍成因的探究多关注于特定认知领域,研究者基于此提出了数量表征缺陷、数量通达缺陷、数字模块缺陷和数量编码缺陷4种理论假设。本文从行为表现、认知过程、神经机制三个层面对这4种假设进行分析,并在此基础上提出了该领域未来的研究方向:全面测量一般认知能力和特定认知能力,加强特定认知领域缺陷的干预,使用个案研究的方法深入揭示发展性计算障碍个体的独特性。In recent years, the exploration of the etiology of developmental dyscalcttlia focuses on the specific cognitive domain, and researchers have proposed such theoretical hypotheses as deficits in the magnitude repre- sentation, the access, the number module, and the numerosity coding. This study, based on an analysis of these hypotheses in terms of behaviors, cognitions and nerves, and offers the future research trends： measuring both general cognitive abilities and specific cognitive abilities, strengthening the interventions in the deficits in the spe- cific cognitive domain, and revealing each individual＇s unique dyscalculia based on a case study.
