【Objective】 To explore the visuospatial working memory capacity in children with mathematical learning disability and the relationship between visuospatial working memory and mathematical skills. 【Methods】 All participants(MLD, n=48, aged 7~12; normal controls, n=48, aged 7~12) screened out by scores of the Chinese Elementary School Students' Mathematical Ability Testing Scale, grades in the final exam, and results of the Combined Ravens standard progressive matrices test(CRT) were conducted visuospatial working memory test with. 【Results】 MLD group scored obviously lower than control group in all factors concerning mathematical skills and visuospatial working memory(P＜0.05). Both the mathematical ability of calculation and logic/visuospatial(r=0.333,P=0.001;r=0.228,P=0.026) were correlated with visuospatial working memory. Figure counting(P=0.036)and block counting(P=0.016) were associated with visuospatial working memory in MLD group, but only multiplication(P=0.043) in control group. 【Conclusion】 Children with MLD are weak in visuospatial working memory and their visuospatial working memory capacity impact on the mathematical ability.
