What does rapid naming tell us about dyslexia?
This article summarizes some of the important findings
from research evaluating the relationship between
poor rapid naming and impaired reading performance.
Substantial evidence shows that dyslexic readers have
problems with rapid naming of visual items. Early research
assumed that this was a consequence of phonological
processing deficits, but recent findings suggest
that non-phonological processes may lie at the root of
the association between slow naming speed and poor
reading. The hypothesis that rapid naming reflects an
independent core deficit in dyslexia is supported by the
main findings: (1) some dyslexics are characterized by
rapid naming difficulties but intact phonological skills;
(2) evidence for an independent association between
rapid naming and reading competence in the dyslexic
readers, when the effect of phonological skills was controlled;
(3) rapid naming and phonological processing
measures are not reliably correlated. Recent research
also reveals greater predictive power of rapid naming, in
particular the inter-item pause time, for high-frequency
word reading compared to pseudoword reading in developmental
dyslexia. Altogether, the results are more
consistent with the view that a phonological component
alone cannot account for the rapid naming performance
in dyslexia. Rather, rapid naming problems may emerge
from the inefficiencies in visual-orthographic processing
as well as in phonological processing.
