The current study investigated which time components of rapid automatized naming (RAN) predict group differences between dyslexic and non‐dyslexic readers (matched for age and reading level), and how these components relate to different reading measures. Subjects performed two RAN tasks (letters and objects), and data were analyzed through a response time analysis. Our results demonstrated that impaired RAN performance in dyslexic readers mainly stem from enhanced inter‐item pause times and not from difficulties at the level of post‐access motor production (expressed as articulation rates). Moreover, inter‐item pause times account for a significant proportion of variance in reading ability in addition to the effect of phonological awareness in the dyslexic group. This suggests that non‐phonological factors may lie at the root of the association between RAN inter‐item pauses and reading ability. In normal readers, RAN performance was associated with reading ability only at early ages (i.e. in the reading‐matched controls), and again it was the RAN inter‐item pause times that explain the association.
