A Timely Look at the Timing Hypothesis of Reading Disability.
Chiappe, Penny; Stanovich, Keith E.; Siegel, Linda S.
A study examined the relationship among temporal processing, phonological processing, and reading skill using a multivariate approach which included measures of phonological processing and a variety of timing tasks that have been implicated in timing theories. Subjects were 30 adults classified as disabled readers based on their performance on the Wide Range Achievement Test 3 (WRAT3) and 32 chronological age controls. The reading measures were Form G of the Woodcock Word Identification and the WRAT3 pretest. Phonological processing was assessed using the Woodcock Word Attack and a phoneme and syllable deletion task. A number of timing tasks were used to test the timing deficit hypothesis. Results did not confirm the main prediction of the timing hypothesis, that reading disabled adults would be impaired on tasks with rapid, but not slow processing demands, although the experimental tasks were sensitive enough to reveal group differences between skilled and disabled readers. Findings make it very unlikely that temporal processing deficits underlie the phonological core deficit of reading disability. It is more likely that naming speed deficits are caused by impairments of word-retrieval (or the naming system) rather than impaired temporal processing. (Contains four tables of data.) (RS)
