Classification of 140 children with developmental reading disabilities found 54 percent demonstrated deficits in both phonological awareness and visual naming speed and these children were more globally impaired than children with a single deficit. Following 35 hours of word identification training, sizable gains and significant generalization of…

This study investigated the relative importance of semantic, grammatical, phonological, and rapid naming abilities in predicting word identification skills in 200 children (grades 1-6) using correlation, factor analysis, multiple regression, and predictive outcome analysis techniques. Composite measures of these abilities correlated significantly…

Elementary students (n=105) with problems in word recognition were given computer-assisted instruction involving either only reading words in context, or reading words in context and completing exercises involving individual words (to increase their phonological awareness). The latter group showed significant gains on tests of phoneme awareness…

Naming speed skills of 45 dyslexic children (mean ages=8, 13, and 17) and slow learning children (mean age=10) were compared with those of normally achieving children. Results indicated that children with dyslexia and slow learners have persistent and severe problems in naming speed for all stimuli, regardless of whether the stimulus requires…

Twenty-three children (ages 10 to 12) with language impairment and 46 typically achieving adults participated in two auditory lexical-decision tasks evaluating effects of phonological opacity on word recognition. Findings indicated that the language-impaired children were less able than controls to identify phonologically opaque…

A sample of 133 Spanish children (ages 8 to 13) was classified by IQ and reading level and given a lexical processing task. The study found that IQ did not explain differences between learning-disabled (LD) or nondisabled (NLD) children in lexical processing. Lexical and sublexical parameters had a greater influence on LD students than NLD…

Ten children (ages 7-10) with visuoperceptual problems were compared to sighted children on lexical decision tasks with words, nonwords, and format distorted items. The partially sighted children relied on phonological mediation as well as the "visual" route in word recognition. Regularity effects, as well as effects of intact and disrupted…

This paper argues that the ability to rapidly compare phonemes is a primary sensory-cognitive function underlying self-correction in word recognition and spelling and thus, indirectly, reading comprehension. Such phonological defects can be addressed both preventively and remedially using procedures that are fundamentally different from typical…

This study compared the effectiveness of reading instruction at the onset-rime level, phoneme level, and whole word level with 48 first graders. Both phoneme and onset-rime groups were significantly more accurate than whole word groups, and there was a tendency for the onset-rime group to outperform all other groups. (Author/DB)

Word recognition data from identical and fraternal twins and siblings (N=172) indicated that the phonological coding deficit of children with reading disabilities was highly heritable. Orthographic coding was not significantly heritable. Poor readers with low IQs were superior to similar reading but average IQ readers in phonological coding.…

This study compared the phonological awareness ability of 11 children (ages 6-8) with persistent phonological impairment to that of 11 phonologically normal children. Phonologically normal children scored higher on three of the four phonological awareness measures, with no differences on word recognition. Speech intelligibility was a significant…

This 5-year study compared 204 first graders, 60 poor reading third graders, and 105 adults who had been evaluated for reading problems in childhood. Results suggest that attention deficit disorder has no impact on the development of word identification skills but does affect long-term educational outcomes. Phonological decoding and rapid naming…

Comparison of two word identification training programs with 122 severely reading disabled children in grades 2 through 6 found both the phonological and the strategy programs resulted in significant improvement in word identification and word attack skills and sizeable transfer-of-training effects. Children at each grade level made equivalent…

Sixteen children with severe reading problems in first grade received a year-long individual tutorial intervention. Growth curve analyses found significant gains on measures of orthographic and phonological coding, word identification, word attack skills, reading comprehension, letter automaticity, and spelling and marginally significant gains in…
