The goal of the present study was to test theories about the extent to which individual differences in word reading align with those in spelling and the extent to which other cognitive and linguistic skills play different roles in word reading and spelling. Using data from 1,116 children ranging from 8 to 17 years, we modeled word reading and…

The processing of morphologically complex words has been studied in many languages, leading to a variety of theoretical accounts. Prime type, individual differences, and cross-linguistic effects have emerged as potential factors in morphological processing, but the findings so far have been inconclusive, especially for young children. This study…

We examined the contribution of a major predictor of basic literacy ability--phoneme awareness--to individual differences in two arithmetic computation tasks: a speeded task consisting of simple computation problems (arithmetic fluency) and an untimed, more complex computation task involving multi-digit operands (numerical operations). The…

Word learning can build the high-quality word representations that support skilled reading and language comprehension. According to the partial knowledge hypothesis, words that are partially known, also known as "frontier words" (Durso & Shore, 1991), may be good targets for instruction precisely because they are already familiar.…

We conducted a study of the effects of assisted reading practice (Shany & Biemiller, 1995). In this paper we examined the original data to find factors affecting gains in reading comprehension. We contrasted 14 children who had below median gains in reading comprehension and 15 who had above median gains. There were no significant correlations…

Across languages, children with developmental dyslexia are known to have impaired lexical phonological representations. Here, we explore associations between learning new phonological representations, phonological awareness, and sensitivity to amplitude envelope onsets (rise time). We show that individual differences in learning novel phonological…

The effect of two training procedures on the development of reading speed in poor readers is examined. One training concentrates on the words the children read correctly ("successes"), the other on the words they read incorrectly ("failures"). Children were either informed or not informed about the training focus. A randomized controlled trial was…

This study investigates word reading skill in Down Syndrome (DS). Two main questions are addressed: (1) Is reading an island of ability in DS? and (2) What are the cognitive correlates of word reading ability in DS? In particular, how do language versus visual-spatial skills relate to individual differences in reading ability in DS? Participants…

The main objective of the present study was to examine the contribution of phonological and orthographic skills to Persian reading and spelling. The Persian language is of interest because it has very consistent grapheme-to-phoneme correspondences, but somewhat inconsistent phoneme-to-grapheme correspondences. Reading, spelling, phonological, and…
