Working memory predictors of mathematics across the middle primary school years

Background Work surrounding the relationship between visuospatial working memory (WM) and mathematics performance is gaining significant traction as a result of a focus on improving academic attainment. Aims This study examined the relative contributions of verbal and visuospatial simple and complex WM measures to mathematics in primary school children aged 6-10 years. Sample A sample of 111 children in years 2-5 were assessed (M-age = 100.06 months, SD = 14.47). Method Children were tested individually on all memory measures, followed by a separate mathematics testing session as a class group in the same assessment wave. Results and Conclusions Results revealed an age-dependent relationship, with a move towards visuospatial influence in older children. Further analyses demonstrated that backward word span and backward matrices contributed unique portions of variance of mathematics, regardless of the regression model specified. We discuss possible explanations for our preliminary findings in relation to the existing literature alongside their implications for educators and further research.
