Predictors for grade 6 reading in children at familial risk of dyslexia

The present study investigates whether grade 6 reading outcomes, reading fluency, and reading comprehension can be predicted by grade 3 reading fluency, familial risk of dyslexia (FR), and grade 3 reading related skills: rapid automatized naming (RAN), phonological awareness (PA), and vocabulary. In a sample of 150 children, of whom 83 had a parent with dyslexia, correlation and regression analyses were performed. FR, measured on a continuous scale, was by itself related to all outcomes. However, FR did not explain any variance on top of grade 3 reading fluency. Grade 3 reading fluency strongly predicted grade 6 reading fluency and was also related to reading comprehension. RAN improved the prediction of grade 6 reading fluency, though the additional explained variance was small. Vocabulary and PA fully explained the variance that grade 3 reading fluency explained in grade 6 reading comprehension. Vocabulary explained a substantial amount of variance in grade 6 reading comprehension making it an interesting clinical target. As we used continuous measures of reading fluency and FR, our findings are not biased by distinct diagnostic criteria.     

Early intervention in the home for children at risk of reading failure

In this study, Ruth Fielding‐Barnsley and Nola Purdie evaluate the effects of an eight‐week dialogic reading intervention with an experimental group of 26 at‐risk children in the year prior to formal schooling. The results on measures of literacy taken during the first year of formal schooling, compared with results of a control group of 23 children, will encourage all those working to involve families in early intervention.     

Enhancing the early literacy development of children at risk for reading difficulties

Abstract

This paper reviews the dynamic and interactive links between the development of children's language, phonological awareness, and reading. Some of the key issues explored are procedures to enhance children's language development, decoding and word recognition skills, along with some relevant assessment and programming strategies that can facilitate children's early reading development. In particular, the paper supports the suggestion that deficits in phonological awareness are often a consequence of slow vocabulary development (a classic marker of language delay) and that teachers need to be able to adapt their language and dialogue interactions for children with language delays.     

The development of children at familial risk for dyslexia: Birth to early school age

Children at risk for familial dyslexia (n = 107) and their controls (n = 93) have been followed from birth to school entry in the Jyvaskyla Longitudinal study of Dyslexia (JLD) on developmental factors linked to reading and dyslexia. At the point of school entry, the majority of the at-risk children displayed decoding ability that fell at least 1 SD below the mean of the control group. Measures of speech processing were the earliest indices to show both group differences in infancy and also significant predictive associations with reading acquisition. A number of measures of language, including phonological and morphological skill collected repeatedly from age three, revealed group differences and predictive correlations. Both the group differences and the predictive associations to later language and reading ability strengthened as a function of increasing age. The predictions, however, tend to be stronger and the spectrum of significant correlations wider in the at-risk group. These results are crucial to early identification and intervention of dyslexia in at-risk children.     

Lessons from the reading brain for reading development and dyslexia*

The purpose of this study was to examine Australian learning difficulties specialists’ knowledge about, and the use of, the term dyslexia. An online survey was constructed based on a current definition of, and evidence about, dyslexia and distributed to members of relevant professional associations. A total of 179 participants responded to the survey. Statistical tests were used to identify significant differences in questionnaire scores between a number of demographic subgroups which included special professional interest group, professional discipline, years of experience and engagement in reading-related university study. Results indicated that these Australian professionals all possess a similar and generally high level of accurate research-based knowledge about dyslexia and how to support individuals with significant reading issues. However, while affirming the relevancy of the term dyslexia in their professional work, most participants preferred another term and favoured a combination of words including reading, learning and the less pejorative term difficulty as opposed to disability. As the term dyslexia is commonly used by Australian educators, policy-makers, support organisation and parents to make decisions about the support individuals receive, an understanding of what is currently understood by this label is critical.     

A longitudinal study of the development of oral reading fluency in young children at risk for reading failure

The purpose of this study was to examine the development of oral reading fluency in a sample of first-grade children. Using growth curve analysis, models of growth were identified for a combined sample of at-risk (AR) and not-at-risk (NAR) children, and predictors of growth were identified for the longitudinal AR sample in first and second grade. Large and serious differences in reading fluency growth between the AR and NAR samples were apparent early, replicating other reports. Theories of sight-word learning and reading fluency were supported, in that letter-sound fluency was a uniquely significant predictor of first-grade reading fluency. The effects of phonological awareness and rapid automatized naming were mediated by the other variables in the model. Growth in first-grade oral reading fluency accounted for the most unique variance in second-grade growth and end-of-year performance. The results suggest that word reading fluency should be regarded as developing concomitantly with early word recognition rather than as a later-developing skill.     

Effects of instruction on beginning reading skills in children at risk for reading disability

Children identified in kindergarten as being at risk for reading disability were taught in grades one and two using one of two methods of reading instruction, a structured phonics code-emphasis approach or an approach emphasizing use of context. At the end of first and second grade, children were tested on measures of achievement in word identification, word attack, passage comprehension and spelling. Those in the Code group earned uniformly higher scores on all achievement measures at the end of first and second grades. At the end of first grade, statistically significant differences between groups were found on nonword reading and spelling of phonetically regular words. At the end of second grade, significant differences were found in reading of polysyllabic real words and decoding of monosyllabic and polysyllabic nonsense words. It was concluded that reading instruction does have an important impact on acquisition of early reading skills, and that structured, systematic phonics instruction results in more favorable outcome than does a context emphasis approach.This research was supported by PHS Grant HD21887 to Bowman Gray School of Medicine and by PHS Grant NS19413 to UNC-Greensboro, Subcontract to Bowman Gray School of Medicine.

Phonological and lexical reading in Italian children with dyslexia

In this study we explore the development of phonological and lexical reading in dyslexic children. We tested a group of 14 Italian children who have been diagnosed with dyslexia and whose reading age is end of grade 1. We compared this group with a group of 70 typically developing children who have been tested for reading at the end of grade 1. For each dyslexic child we also selected a participant who was attending the same grade, was close in age, and showed typical reading development when tested with a narrative passage reading task (Cornoldi, Colpo, & Gruppo MT, 1981) for correctness and reading speed. Children in this group are “same grade controls.” We used a reading task consisting of 40 three syllables words. A qualitative and quantitative method of coding children’s naming allowed us to distinguish several components of their reading performance: the grapheme and word recognition, the size of orthographic units involved in the aloud orthography–phonology conversion, the reading process used to recognize words. The comparison of the dyslexic group with the reading age and the same grade control groups reveals different trends of delayed reading processes. Considering dyslexic children’s chronological age, lexical reading is greatly delayed. Considering dyslexic children’s reading age, the type of reading process that is more deeply delayed is phonological reading. The rate of fragmented phonological reading (i.e., a type of syllabized phonological reading) is much higher in dyslexic children compared to the reading age group, suggesting that some factors undermine the possibility of internalizing the orthography–phonology conversion and the blending processes.     

Improving teacher prediction of children at risk for reading failure

Whether screening tests or teacher ratings best predict children at risk for reading failure continues to be an area of disagreement in the early identification literature. Our early studies confirmed low positive identification rates (30%) when kindergarten teachers were asked to predict future reading achievement using a traditional rating scale, while a project-developed, theory-based screening battery correctly identified 81% of poor readers. Construction of a teacher rating scale of current skill levels on research-validated precursors to reading improved prediction in the current study, although results were still inferior to the screening test (64% and 80% valid positives, respectively). Combining test results and teacher ratings resulted in 88% identification of those who failed in first, second, or third grade, suggesting that both teacher ratings and screening tests should be used to identify the largest number of those who will later fail in reading. © 1998 John Wiley & Sons, Inc.     

Phonological processes as predictors of specific reading skills in children at risk for reading failure

Children at risk for reading disability were evaluated as kindergartners and again as first graders to determine (1) intercorrelations among phonological processing tasks and (2) the relationship of such tasks to word identification and word attack. With IQ controlled, there were no intercorrelations among measures of phonological awareness, phonetic recoding in working memory, and phonological recoding in lexical access. Thus, these results failed to substantiate the concept of a general phonological processing ability. Partial correlations controlling for IQ revealed no relationship between reading and phonological awareness or phonetic recoding in working memory. In contrast, lexical access measures were significantly, albeit moderately, correlated with word identification but not word attack. Word attack and word identification were predicted by different combinations of variables. These results suggest that lexical access ability is an important factor in reading acquisition and that different combinations of phonological processes may be related to different aspects of reading.This research was supported by PHS grant HD 21887 to Bowman Gray School of Medicine and by PHS Grant NS 19413 to UNC-Greensboro Subcontract to Bowman Gray School of Medicine.     

Mothers' causal attributions concerning the reading achievement of their children with and without familial risk for dyslexia

The present study analyzed data from the Jyv?skyl? Longitudinal Study of Dyslexia to investigate the factors to which mothers of children with and without familial risk for dyslexia attribute the causes of their first-grade children's reading achievement. Mothers' causal attributions were assessed three times during their children's first school year. Children's verbal intelligence was assessed at 5 years and their word and nonword reading skills at 6.5 years. The results showed that the higher the word reading skills the children had, the more their mothers attributed their success to ability than to effort. However, if children had familial risk for dyslexia, their mothers' attribution of success to ability decreased during the first grade as compared with the ability attributions of mothers whose children were in the control group.     

Enhancing orthographic knowledge helps spelling production in eight-year-old Chinese children at risk for dyslexia

We investigated the effects of enhancing orthographic knowledge on the spelling of Chinese characters and words in 131 eight-year-old Chinese children at risk for dyslexia. The traditional approach (37 children) emphasizing memory and repeated writing was the control condition. The analytic and synthetic approach (ASA, 33 children) stressed insight into character structure. The integrated analytic and synthetic approach added to ASA self-correction and metacognitive activities (INA, 61 children). The children were first asked to write down as many words as possible associated with pictures of home, school, and community; the correctly written words formed the baseline information. The children were then instructed by their classroom teachers in six especially designed short texts and assessed in eight measurable bujian or radical tasks subserving three constructs: morpheme completion, bujian analysis and synthesis and bujian compounding. Multivariate analyses of variance showed that the children in the INA condition outperformed those in the other conditions in three of the measurable bujian tasks. A confirmatory factor analysis verified the stability of the eight tasks and their clustering into three constructs. From these results, we tentatively propose a “bujian sensitivity hypothesis” as a means of helping young Chinese children at risk for spelling disorders.     

Dutch home-based pre-reading intervention with children at familial risk of dyslexia

Children (5 and 6 years old, n = 30) at familial risk of dyslexia received a home-based intervention that focused on phoneme awareness and letter knowledge in the year prior to formal reading instruction. The children were compared to a no-training at-risk control group (n = 27), which was selected a year earlier. After training, we found a small effect on a composite score of phoneme awareness (d = 0.29) and a large effect on receptive letter knowledge (d = 0.88). In first grade, however, this did not result in beneficial effects for the experimental group in word reading and spelling. Results are compared to three former intervention studies in The Netherlands and comparable studies from Denmark and Australia.

Computer-assisted instruction to prevent early reading difficulties in students at risk for dyslexia: Outcomes from two instructional approaches

The relative effectiveness of two computer-assisted instructional programs designed to provide instruction and practice in foundational reading skills was examined. First-grade students at risk for reading disabilities received approximately 80 h of small-group instruction in four 50-min sessions per week from October through May. Approximately half of the instruction was delivered by specially trained teachers to prepare students for their work on the computer, and half was delivered by the computer programs. At the end of first grade, there were no differences in student reading performance between students assigned to the different intervention conditions, but the combined-intervention students performed significantly better than control students who had been exposed to their school’s normal reading program. Significant differences were obtained for phonemic awareness, phonemic decoding, reading accuracy, rapid automatic naming, and reading comprehension. A follow-up test at the end of second grade showed a similar pattern of differences, although only differences in phonemic awareness, phonemic decoding, and rapid naming remained statistically reliable.     

A meta-analysis of the RTI literature for children at risk for reading disabilities

This article synthesizes the literature comparing at-risk children designated as responders and low responders to interventions in reading. The central question addressed in this review is whether individual differences in reading-related skills at pretest predict responders at posttest across a variety of interventions and sets of criteria for determining responding and low responding. A total of 13 studies met criteria for the meta-analysis, yielding 107 weighted effect sizes (ESs) at posttest (M = .76, SE = .03, 95% confidence interval [CI] =.71, .81) and 108 weighted ESs at pretest (M = 1.02, SE = .03, CI = 1.02, 1.13). The results showed that the magnitude of ES between responders and low responders increased from pretest to posttest on measures of reading (e.g., real word identification = 1.06 vs. 1.53, word attack = 1.10 vs. 1.28, and passage comprehension, 0.45 vs. 1.43). Hierarchical linear modeling indicated that overall posttest ESs were significantly moderated by pretest scores as well as the type of measure administered, whereas no significant moderating effects were found for number of weeks of intervention, length of sessions, number of sessions, type of intervention (one-to-one vs. small group instruction), and criteria for defining responders (cutoff, scores, discrepancy, benchmark). Overall, the synthesis suggested that regardless of type of treatment and identification criteria, response-to-intervention (RTI) conditions were not effective in mitigating learner characteristics related to pretest conditions.     

Dyslexie font does not benefit reading in children with or without dyslexia

In two experiments, the claim was tested that the font “Dyslexie”, specifically designed for people with dyslexia, eases reading performance of children with (and without) dyslexia. Three questions were investigated. (1) Does the Dyslexie font lead to faster and/or more accurate reading? (2) Do children have a preference for the Dyslexie font? And, (3) is font preference related to reading performance? In Experiment 1, children with dyslexia (n?=?170) did not read text written in Dyslexie font faster or more accurately than in Arial font. The majority preferred reading in Arial and preference was not related to reading performance. In Experiment 2, children with (n?=?102) and without dyslexia (n?=?45) read word lists in three different font types (Dyslexie, Arial, Times New Roman). Words written in Dyslexie font were not read faster or more accurately. Moreover, participants showed a preference for the fonts Arial and Times New Roman rather than Dyslexie, and again, preference was not related to reading performance. These experiments clearly justify the conclusion that the Dyslexie font neither benefits nor impedes the reading process of children with and without dyslexia.     

Phonology,reading development,and dyslexia: A cross-linguistic perspective

In this paper, I present a theoretical overview at the cognitive level of the role of phonological awareness in reading development and developmental dyslexia across languages. My assumption is that the primary deficit in developmental dyslexia in all languages lies in representing speech sounds: a deficit in “phonological representation.” I will argue that this deficit manifests in somewhat different ways, depending on orthography. I will also argue that the phonological deficit in dyslexia is initially at the syllable and onset-rime levels of phonological awareness, with the development of “phonemic” awareness being a consequence rather than a precursor of reading. Finally, I will suggest that some of the processes underpinning language acquisition are disrupted in dyslexia, in particular, the detection of rhythm in speech.
