Summary

Working memory (WM) deficits are fundamental problems of children with average intelligence but with specific learning disorders in reading and/or math. Depending on the task, these deficits manifest themselves as a domain-specific storage constraint (i.e., the inefficient accessing and availability of phonological representations, e.g., numbers, phonemes) and/or a domain-general monitoring constraint (limitations in controlled attentional processing, i.e., updating, inhibition). Recent studies suggest that growth in the executive component of WM is significantly related to such children’s growth in reading and/or math. Although constraints in WM can be modified, WM constraints in performance in children with reading disorders (RD) and/or math disorders (MD) remain when compared to their average achieving counterparts across a broad age span. Taken together, children with RD and/MD suffer fundamental problems related to the phonological loop (STM) and controlled attention (executive) component of WM.
