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…

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…

Phoneme awareness, letter knowledge, and rapid automatized naming (RAN) are well-known kindergarten predictors of later word recognition skills, but it is not clear whether they predict developments in accuracy or speed, or both. The present longitudinal study of 172 Danish beginning readers found that speed of word recognition mainly developed…

Models of irregular word reading that take into account both child- and word-level predictors have not been evaluated in typically developing children and children with reading difficulty (RD). The purpose of the present study was to model individual differences in irregular word reading ability among 5th grade children (N = 170), oversampled for…

We had 3 aims in the present study: (a) to examine the dimensionality of various evaluative approaches to scoring writing samples (e.g., quality, productivity, and curriculum-based measurement [CBM] writing scoring), (b) to investigate unique language and cognitive predictors of the identified dimensions, and (c) to examine gender gap in the…

Examined manuscript letter writing skills of students in Grades 1-3. Three letter characteristics, grade, and alphabet fluency each made a significant contribution to the prediction of letter legibility after effects of other predictors were controlled. Letter legibility in turn made a significant contribution to the prediction of text legibility…
