The Effectiveness of Working Memory Training for Children With Low Working Memory.

Subgroups of children may benefit more from working memory training than others. In this study, we aimed to examine whether response to the Cogmed Working Memory Training program differed for children with low IQ and elevated attention-deficit/hyperactivity disorder, emotional and behavioral symptoms, special health care needs, or by sex. We used data from the Memory Maestros trial, a population-based randomized controlled trial of the Cogmed program delivered at school ( After training, improved working memory standard scores (>1 SD) from baseline to 6 months were observed for approximately one-third of the children, with more than half maintaining stable scores (within 1 SD). However, similar outcomes were observed for children receiving usual teaching. Differential effect of Cogmed versus usual teaching was evident for children with elevated hyperactivity and/or inattention, who were less likely to show improved visuospatial working memory, but not for other subgroups studied. Children with elevated hyperactivity and/or inattention were less likely to show clinically meaningful improvement after Cogmed; however, differential effects were not evident for children with low IQ and elevated emotional and behavioral symptoms, special health care needs, or by sex. More research is needed to determine if training can improve working memory and, if so, for whom.
