The working memory system supports learning processes such as acquiring new information and the development of new skills. Working memory has been found to be related to both early literacy and early numeracy in kindergarten and to linguistic and mathematical academic skills at older ages, but the contribution of each of the memory components at these ages is not yet clear. The purpose of this study is to examine the unique connections among the various systems of WM, early literacy, and early numeracy using various assessment tests of simple WM and complex WM, as well as a variety of tasks in math and language skills administered to the same 250 children in kindergarten and 150 children in first grade. Consistent with the predictions, significant relations among all components of memory and mathematics and language knowledge at both ages were found, although these connections were differential for the different types of tasks and memory systems. The connection of complex WM was stronger in its contribution and more significant in first grade in both mathematics and language domains. Complex WM resources were more important in early literacy at kindergarten age, while simple WM seems to be important in early numeracy. The theoretical and educational implications of these results are discussed accordingly.

Background: The working memory (WM) system is recognized as a crucial cognitive function that underpins the acquisition of new knowledge and the development of foundational skills during childhood. Children's early literacy and numeracy skills lay the foundation for future academic success in reading and mathematics. While previous research has established a link between WM and early literacy as well as numeracy, the specific contributions of different WM components to the development of various skills in kindergarten-aged children remain unclear. Objective: This study aimed to investigate the associations between distinct profiles of WM and academic achievements in early literacy and numeracy among kindergarten children. Method: A battery of memory tests (simple WM and complex WM) were administered to a cohort of 250 kindergarten children aged between five and seven years. Additionally, a range of tasks assessing mathematical and language skills were administered. Results: Our findings align with our initial hypotheses, revealing differences between profiles of simple WM and complex WM in relation to early mathematics and language skills. Generally, children who exhibited higher WM abilities outperformed their peers who had lower WM capabilities. Conclusion: This study emphasizes the critical role of WM in early childhood education. Children with limited WM function are at a heightened risk of academic underachievement. Furthermore, both components of WM--simple WM and complex WM--emerge as influential factors in shaping children's proficiency in early literacy and numeracy skills.
