Assessing the contribution of lexical quality variables to reading comprehension
in deaf and hearing readers

Reading builds on a spoken language foundation and the quality of phonological forms plays a central role in reading development for hearing readers. Skilled deaf readers however are likely to have relatively coarse-grained phonological codes compared to hearing readers due to reduced access to spoken language. In what ways does the reading system successfully adapt for adult deaf readers? The Lexical Quality Hypothesis proposes that variations in the quality of word representations has consequences for reading comprehension (Perfetti, 2007). We evaluated the relative contribution of the lexical quality (LQ) variables – orthographic (spelling), phonological, and semantic (vocabulary) knowledge – to reading comprehension in adult deaf ASL signers and hearing nonsigners using regression models to predict reading skill (PIAT and Woodcock Johnson (WJ) comprehension subtests). We hypothesized that the primary predictor of reading comprehension for deaf readers lies in the quality of orthographic representations and robust orthographic-to-semantic mappings, whereas the quality of phonological representations will be strongly predictive of reading comprehension for hearing readers. The preliminary results revealed that for deaf readers, LQ variables predicted 28% of the variance in PIAT scores (after eliminating covariates such as nonverbal reasoning skills) and 18% of the variance in WJ scores. Semantics and orthography, not phonology, predicted reading comprehension for deaf readers. For hearing readers, LQ variables predicted 14% of variance in PIAT scores and 56% in WJ scores. Phonology was the strongest predictor of reading comprehension (with semantics also predicting WJ scores). We conclude that 1) strong orthographic and semantic representations, rather than precise phonological representations, predict reading skill in deaf adults and 2) the predictive strength of LQ variables may depend upon how reading comprehension is measured.
