Purpose: Two types of orthographic knowledge were examined: i) knowledge of permissible letter combinations (general orthographic knowledge) and ii) knowledge of whole words (word-specific orthographic knowledge), to gain further insights into the relationship of general and word-specific orthographic knowledge with literacy skills. Method:…

Deficits in reading fluency and in spelling can dissociate during development, resulting in groups with reading deficit only (RD), spelling deficit only (SD) and combined reading and spelling deficit (RSD). The current study investigated the one-to-two-year longitudinal stability of these subgroups in 167 German-speaking children. Reading fluency…

Phonological coding plays an important role in reading for hearing students. Experimental findings regarding phonological coding in deaf readers are controversial, and whether deaf readers are able to use phonological coding remains unclear. In the current study we examined whether Chinese deaf students could use phonological coding during…

We examined the manifestation of dyslexia in a cross-linguistic study contrasting English and Greek children with dyslexia compared to chronological age and reading-level control groups on reading accuracy and fluency, phonological awareness, short-term memory, rapid naming, orthographic choice, and spelling. Materials were carefully matched…

Purpose: To assess strengths and weaknesses of the reading level (RL) match approach and its potential to generate insights regarding the cognitive foundations of reading ability and disability. Method: We applied RL-match design to a sample of 2nd-6th graders reading a consistent orthography, Russian, using an "extreme phenotype"…

Effects of orthographic depth on orthographic learning ability were examined in 10- to 13-year-old children who learnt to read in similar orthographies differing in orthographic depth, defined as consistency of grapheme-to-phoneme correspondences. Danish children who learnt to read a deep orthography underperformed their Swedish counterparts who…

Two explanations for resolving dyslexia were investigated, one assuming resolving underlying deficits and another assuming compensatory mechanisms based on cognitive strengths. Thirty-six Dutch gifted secondary-school students with either persistent (n = 18) or resolving (n = 18) dyslexia participated. Groups, matched on IQ, were assessed on…

It has been hypothesized that students with dyslexia struggle with writing because of a word-level focus that reduces attention to higher level textual features (structure, theme development). This may result from difficulties with spelling and/or difficulties with reading. Twenty-six Norwegian upper secondary students (M = 16.9 years) with weak…

We evaluated two experimenter-delivered, small-group word reading programs among at-risk poor readers in Grade 1 classes of regular elementary schools using a two-arm, dual-site-matched control trial intervention. At-risk poor word readers (n = 201) were allocated to either (a) Direct Mapping and Set-for-Variability (DMSfV) or (b) Current or…

We studied the relationship between rapid serial naming (RSN) and orthographic processing in Russian, an asymmetrically transparent orthography. Ninety-six students (M age = 13.73) completed tests of word and pseudoword reading fluency, spelling, orthographic choice, phonological choice, phoneme awareness (PA), and RSN. PA was a better predictor…

We examined the efficacy of 20 weeks of individual supplemental phonics-based instruction for language minority (LM) and non-LM first graders. Students were designated LM if the primary home language was not English (otherwise non-LM). Those performing in the bottom half of their classroom LM/non-LM group in letter knowledge and phonological…

The purpose of this study is to examine the effects of morphological instruction on language and literacy outcomes by synthesizing 92 standardized mean differences (d) from 30 independent studies. Findings show a moderate overall effect of morphological instruction ([d-bar] = 0.32), suggesting that children receiving morphological instruction…

In three large samples (N = 1248) of children learning to read German we investigated the correlations between rapid automatized naming (RAN), phonological awareness (PA), phonological decoding (nonword reading fluency), and orthographic processing (word reading fluency and spelling). In a series of hierarchical regression analyses, RAN explained…

This study examines the longitudinal relations among early literacy experiences at home and children's kindergarten literacy skills, Grade 1 word reading and spelling skills, and Grade 4 reading comprehension, fluency, spelling, and reading for pleasure. Ninety French-speaking children were tested at the end of kindergarten and Grade 1, and 65…
