摘要
本研究应用考察视听通道下非符号、符号数量加工及符号与非符号转换能力的基本数量加工能力测验,测查北京市2057名一至六年级小学生的基本数量加工能力及发展特征,并筛查存在基本数量加工能力缺陷的计算障碍儿童,分析其认知能力特征。结果发现,儿童的基本数量加工能力随年级增长不断发展完善,在五、六年级趋于平稳;存在基本数量加工能力缺陷的计算障碍儿童,在计算成绩上显著低于普通儿童,而在一般认知能力上无显著性差异。以上结果表明,对于计算障碍儿童,未来研究需重点关注其基本数量加工能力缺陷,并及时进行有针对性的干预训练。
In order to explore the basic numerical magnitude processing deficit and cognitive characteristics of children with dyscalculia, the present study examined the performance of 2057 students from first to sixth grade on the basic numerical magnitude processing test in primary schools in Beijing. The results showed that： （1）the basic numerical magnitude processing abilities of children developed along with age and grade, and became stable when they reached the fifth or six grade; （2）children with dysealculia and basic numerical magnitude processing deficit had significant impairment in completing arithmetic task, but not in the tasks of general cognitive abilities. The results indicated that the future researehes on children with dysealeulia might need to focus on their basic numerical magnitude processing deficit and developing effective intervention methods for children with dysealctdia.
