In the search for mechanisms that contribute to dyslexia, the term "attention" has been invoked to explain performance in a variety of tasks, creating confusion since all tasks do, indeed, demand "attention." Many studies lack an experimental manipulation of attention that would be necessary to determine its influence on task…

Purpose: We examined the neurocognitive bases of lexical morphology in children of varied reading abilities to understand the role of meaning-based skills in learning to read with dyslexia. Method: Children completed auditory morphological and phonological awareness tasks during functional near-infrared spectroscopy neuroimaging. We first examined…

The Double Deficit Hypothesis of dyslexia is one approach to classifying students with reading disabilities. The theory offers four distinct groups of readers: (a) average readers, (b) students with phonological deficits, (c) students with naming speed deficits, and (d) students with double deficits: those having both (b) and (c). This study…

This study examines the concurrent relationships between phoneme awareness, visual-verbal paired-associate learning, rapid automatized naming (RAN), and reading skills in 7- to 11-year-old children. Path analyses showed that visual-verbal paired-associate learning and RAN, but not phoneme awareness, were unique predictors of word recognition,…

This study investigated the effects of syntactic complexity on written sentence comprehension in compensated adults with dyslexia. Because working memory (WM) plays a key role in processing complex sentences, and individuals with dyslexia often demonstrate persistent deficits in WM, we hypothesized that individuals with dyslexia would perform more…

The role of morphology in reading aloud was examined measuring naming latencies to pseudowords and words composed of morphemes (roots and derivational suffixes) and corresponding simple pseudowords and words. Three groups of Italian children of different ages and reading abilities, including dyslexic children, as well as one group of adult readers…

Research on dyslexia has focused on the phonological level of linguistic analysis. Here we extend the investigation of the linguistic competence of individuals with dyslexia to the morphological level of linguistic analysis. We examine whether adult Hebrew readers with dyslexia extract and represent morphemic units similarly to normal readers.…

Vocabulary growth was suggested to prompt the implementation of increasingly finer-grained lexical representations of spoken words in children (e.g., [Metsala, J. L., & Walley, A. C. (1998). "Spoken vocabulary growth and the segmental restructuring of lexical representations: precursors to phonemic awareness and early reading…

The present findings are drawn from the Jyvaskyla Longitudinal Study of Dyslexia (JLD), in which approximately 100 children with familial risk of dyslexia and 100 control children have been followed from birth. In this paper we report data on the reading development of the JLD children and their classmates, a total of 1,750 children from four…

A lexical decision study with two groups of tertiary students (n=43) differing in their Chinese language ability found that even for adult readers differing in their Chinese language ability, lexicality, frequency of characters, and the consistency of semantic radicals affect accurate and rapid character identification. Teaching suggestions are…

A discrete-trial reaction time methodology was employed measuring speeds of skilled and less skilled readers in naming colors, pictures, numbers, letters, and words. Less skilled nondyslexic children don't exhibit a general name retrieval deficit; rather, research shows phonological analysis skills are integral in early reading acquisition.…

Evaluates the hypothesis that dyslexic children have a specific deficit in phonological reading processes to elucidate the characteristics of developmental dyslexics' reading skills. Finds no evidence for distinct subtypes of dyslexia, although recent conceptualizations of reading development provide a better framework in which to investigate…

This paper describes characteristics of 10-year-old children (n=422) with normal reading ability, but with some signs of dyslexia. Findings indicated these children obtained different results on five measures associated with dyslexia than did other normal achievers without such signs. Measures were underachievement at word recognition, spelling,…

Fifty-three children (ages 9-13) with dyslexia completed a summer tutoring program that emphasized word-building skills. Children who received piracetam (a purportedly memory-enhancing drug) did not improve more than nonmedicated children in any aspect of reading. Children subtyped as "phonetic" improved significantly more in…

Explores how well measures of verbal short-term memory and naming speed tasks predict children's reading achievement under various IQ control conditions. Both were effective, but when controlling for verbal IQ, memory measures are less reliable, whereas digit-naming speed remains a significant predictor of reading achievement. (MM)
