| Abstract: | Reading fluency beyond decoding is a limitation to many children with developmental reading disorders. In the interest of
remediating dysfluency, contributing factors need to be explored and understood in a developmental framework. The focus of
this study is orthographic processing in developmental dyslexia, and how it may contribute to reading fluency. We investigated
orthographic processing speed and accuracy by children identified with dyslexia that were enrolled in an intensive, fluency-based
intervention using a timed visual search task as a tool to measure orthographic recognition. Results indicate both age and
treatment effects, and delineate a link between rapid letter naming and efficient orthographic recognition. Orthographic efficiency
was related to reading speed for passages, but not spelling performance. The role of orthographic learning in reading fluency
and remediation is discussed. |
