Subtyping Among Normal Adult Readers

Various researchers have supported the idea that there exist both surface and phonological subtypes within developmental dyslexia. This study examined whether a subtyping scheme for reading could apply to the general adult population. Additionally, it compared those results with a second study using dyslexic individuals. One hundred thirty-five undergraduates were tested on measures of regular, irregular, and nonword reading. Thirty-three subjects were classified into a phonological subtype and 23 as a surface subtype. Participants were also tested on various reading and non-reading tasks. Differences between groups were noted with those tasks. As a comparison, 27 dyslexic undergraduates were typed. These participants completed comparable measures. Four dyslexic students were classified as surface type and 17 were classified as phonological. Differences were also noted, within the subtypes, for the various accompanying measures. The results of this study support the hypothesis that the typological symptoms shown by dyslexics are a reflection of normal reading processes.
