Visual Deficits in Developmental Dyslexia: Relationships between Non-Linguistic Visual Tasks and Their Contribution to Components of Reading
Jones, Manon W.; Branigan, Holly P.; Kelly, M. Louise
Dyslexia, v14 n2 p95-115 May 2008
Developmental dyslexia is often characterized by a visual deficit, but the nature of this impairment and how it relates to reading ability is disputed ("Brain" 2003; "126": 841-865). In order to investigate this issue, we compared groups of adults with and without dyslexia on the Ternus, visual-search and symbols tasks. Dyslexic readers yielded more errors on the visual-search and symbols tasks compared with non-dyslexic readers. A positive correlation between visual-search and symbols task performance suggests a common mechanism shared by these tasks. Performance on the visual-search and symbols tasks also correlated with non-word reading and rapid automatized naming measures, and visual search contributed independent variance to non-word reading. The Ternus task did not discriminate reading groups nor contributed significant variance to reading measures. We consider how visual-attention processes might underlie specific component reading measures. (Contains 6 figures, 5 tables and 1 note.)
