Cognitive deficits in Chinese children with low mathematical performance : phonological loop visual-spatial sketchpad and central executive functioning

by Wong, Siu-chun

Abstract (Summary)
(Uncorrected OCR) Abstract The role of working memory deficits in mathematic difficulties had been debatable. The present study attempted to address the controversy by obtaining a comprehensive picture of different forms of working memory in Chinese 9-year old children with difficulties specific to mathematics, i.e. having normal reading (LM), and compared with both children having difficulties specific to reading (LR) and normal control (NC). A battery of 8 tasks was used to assess different aspects of working memory, including components in phonological, visual-spatial and central executive functions. Relative to NC, LM were ft T impaired on the dynamic aspects of phonological loop and visual-spatial sketchpad that required active processing, the switch of attention between simultaneous tasks in both verbal and visual stimuli, and long-term retrieval. Compared to LR, LM were impaired only on the visual aspects. These deficits in active processing and executive aspects of working memory were found associated with Mathematic attainment. Further regression analysis showed that different forms of working memory were involved in mathematics and reading performance. It was found that mathematical performance was not only related to some aspects of visual-spatial sketchpad but also the phonological loop. More specifically, the importance of working memory tended to lie in active processing of both subsystems. Lastly, the role of strategy retrieval and application also deserves further investigation.
