Set for variability (SfV) is an oral language task that requires an individual to disambiguate the mismatch between the decoded form of an irregular word and its actual lexical pronunciation. For example, in the task, the word wasp is pronounced to rhyme with clasp (i.e. /waesp/), and the individual must recognize the actual pronunciation of the…

This study shows that home literacy activities contribute to kindergarten children's higher-level comprehension processes, namely knowledge integration and knowledge access. Kindergarten children completed measures assessing literacy and language skills and then their performances on these measures were correlated with home literacy activities,…

The two major determinants of reading comprehension are language comprehension and decoding, but prior studies of the development of reading comprehension from an early age show inconsistent results. To clarify these inconsistencies we report a 6-year longitudinal study (starting at Age 4 years) where we control for measurement error and track the…

There appears to be a close and probably causal relationship between early variations in phoneme skills and later reading skills in typically developing children, though the pattern in children with Down Syndrome is less clear. We present the results of a 2-year longitudinal study of 49 children with Down Syndrome (DS) and 61 typically developing…

In this study, we examined the influence of word-level phonological and lexical characteristics on early phoneme awareness. Typically developing children, ages 61 to 78 months, completed a phoneme-based, odd-one-out task that included consonant-vowel-consonant word sets (e.g., "chair-chain-ship") that varied orthogonally by a phonological…

This article reports findings from a longitudinal investigation of predictors of reading achievement for English-language learners receiving reading instruction in an English-language curriculum. Using the Dynamic Indicators of Basic Early Literacy Skills (DIBELS) assessments, the study examined the predictive relationships of various measures of…

Although research documents a key contribution of print skills to early literacy, vocabulary and other language skills also provide an important foundation. Focusing on a sample of several hundred low-income children in 16 urban schools that were implementing literacy interventions, 1st-grade predictors of literacy development were traced over…

Research on reading has tried, and failed, to account for wide disparities in reading skill even among children taught by the same method. Why do some children learn to read easily and quickly while others, in the same classroom and taught by the same teacher, don't learn to read at all? In "Language Development and Learning to Read", Diane…
