Working memory is a complex cognitive system responsible for the concurrent storage and processing of information. Ggiven that a complex cognitive task like mental arithmetic clearly places demands on working memory (e.g., in remembering partial results, monitoring progress through a multi-step calculation), there is surprisingly little research exploring the possibility of increasing young children’s working memory capacity through systematic school-based training. Tthis study reports the preliminary results of a working memory training programme, targeting executive processes such as inhibiting unwanted information, monitoring processes, and the concurrent storage and processing of information. Tthe findings suggest that children who received working memory training made significantly greater gains in the trained working memory task, and in a non-trained visual-spatial working memory task, than a matched control group. Moreover, the training group made significant improvements in their mathematical functioning as measured by the number of errors made in an addition task compared to the control group. Tthese findings, although preliminary, suggest that school-based measures to train working memory could have benefits in terms of improved performance in mathematics.

While there is little doubt that there is a connection between mathematics anxiety and poor mathematical performance, the direction and nature of this connection is less clear. Some researchers (e.g., Ma & Xu, 2004) have contended that poor mathematical performance directly causes mathematics anxiety. Others see a more complex relationship in which mathematics anxiety may, in part at least, cause poor mathematical performance. One possible explanation for the latter view is that mathematics anxiety leads directly to a disruption of cognitive processes such as working memory, which leads directly to poorer mathematical performance (Hopko, Ashcraft, Gute, Ruggiero, & Lewis, 1998). The working memory component most consistently associated with mathematics anxiety is the central executive (Ashcraft & Krause, 2007), although there is evidence (Miller & Bichsel, 2004) that visual-spatial working memory is impaired by mathematics anxiety. This study sought to explore the suggestion (Ashcraft & Kirk, 2001) that the mere presence of digits might trigger an anxious reaction among children reporting high levels of mathematics anxiety, leading to a decrement in working memory performance. Children of 9 and 10 years of age reported levels of mathematics anxiety and undertook two working memory tasks, one measuring central executive functioning and the other measuring visual-spatial working memory. Each working memory task was completed twice, once using letters as the to-be-remembered stimuli and again using digits. The differences in performance between the two versions of the tasks were compared with the reported levels of mathematics anxiety. The findings suggest that the presence of digits as the stimuli caused a decrement in working memory performance commensurate with the reported levels of mathematical anxiety.

While there is little doubt that there is a connection between mathematics anxiety and poor mathematical performance, the direction and nature of this connection is less clear.
