This study aimed to (a) explore the roles of cognitive and language variables in predicting reading abilities of two groups of individuals with reading disabilities (i.e., dyslexia and specific language impairment) and (b) examine which variable(s) is the most predictive in differentiating two groups. Inclusion/exclusion criteria applied to…

Recent research on developmental dyslexia has suggested a phonological core deficit hypothesis (e.g., Manis, Seidenberg, Doi, McBride-Chang, & Peterson, 1996; Stanovich, Siegel, & Gottardo, 1997) whereby pure cases of developmental phonological dyslexia (dysfunctional phonetic decoding processing but normal sight vocabulary processing) can exist,…

The present research investigated the relationship between Rapid Automatized Naming (RAN) performance, letter-string reading measures of sight vocabulary (SV) and phonetic decoding (PD), and lexical decision. Criterion-based naming rates were obtained from three types of RAN tasks: digits, letters, and letter sounds. Latency measures were obtained…

The responses of 84 children (42 in kindergarten and 42 in first grade) while trying to identify sight words that were similar in sound (bowl/pole), similar in sound and shape (boat/boot), or dissimilar (cup/moon) yielded information about phonetic composition as a source of information by which beginning readers identify sight words. The…

Investigates whether prereaders who knew all their letters are better at forming logographic access routes than letter-sound access routes into memory from words read by sight. Concludes that prereaders become capable of forming letter-sound access routes when they learn letters well enough to take advantage of the phonetic cues the letters…
