Nonword Reading Fluency Research Articles

Are different reading problems associated with different anxiety types?

AbstractThere is a reliable association between poor reading and anxiety, but we do not completely understand the specifics of this relationship. The current study included a sample of children (N = 284; Mage = 9.30, SDage = 1.31) who completed a reading (word, nonword, and text reading accuracy, word, nonword, and text reading fluency, passage reading comprehension) and anxiety (social anxiety, generalized anxiety, separation anxiety, physical injury fears/phobias, panic, obsessive compulsive symptoms) assessment. Analyses included bivariate and partial correlations, principal components analysis, and hierarchical clustering. We found a very tentative suggestion in the data that there may be a specific yet weak association between reading accuracy and social anxiety. The clinical implications and directions for future research are discussed.

Word Reading Accuracy as a Mediator for Fluency

This paper aims to test the predictive role of nonword reading abilities (accuracy and fluency) and rapid naming (RAN) over word reading fluency. Letter knowledge (LK) and phonological awareness (PA) for literacy were accounted for as control factors due to their ceiling effects. We test the direct impact of the main predictors and their indirect outcomes by controlling for word reading accuracy. To this end, 206 children participated and completed measures for nonword reading abilities, rapid naming, word reading accuracy, fluency, and letter knowledge, and phonological awareness. The results show that RAN and nonword reading accuracy are direct predictors of word reading accuracy. Word reading fluency is significantly associated with rapid naming. The effect of RAN, nonword reading accuracy, nonword reading fluency on word reading fluency is partially mediated by word reading accuracy. We discuss the practical implications.

A preliminary evaluation of a manualised intervention to improve early literacy skills in children with Developmental Language Disorder

Children with Developmental Language Disorder (DLD) commonly present with oral language weaknesses which disrupt the development of literacy and impede related academic progress. While there is evidence to support the delivery of manualised Tier 2 interventions with this population, little is known about the effects of Tier 1 interventions. A retrospective cohort comparison was used to evaluate whether there was an observable effect of a manualised Tier 1 intervention compared to ‘business-as-usual’ on early literacy skills for children with DLD. Participants were 140 children attending a specialised education program with equivalent oral language skills and alphabetic knowledge at baseline. After 18 months formal literacy intervention, both groups were assessed on measures of early literacy skills. The differences between group means on all measures favoured the manualised intervention group, and they performed significantly better on a measure of nonword reading fluency. The findings indicate that a manualised Tier 1 intervention may be advantageous for children with DLD in developing proficiency in phonological recoding. This research contributes to the sparse evidence-base supporting the implementation of Tier 1 interventions for at risk populations, and findings warrant future research using experimental designs with tighter controls.

Examining the growth trajectories and cognitive predictors of reading in a consistent orthography: Evidence from a 10-year longitudinal study

AbstractWe examined the growth trajectories of reading in a consistent orthography (Greek) in two developmental periods (from Grade 1 to Grade 4 and from Grade 4 to Grade 10) and what cognitive skills predict the growth patterns. Seventy-five Greek-speaking children were assessed in Grades 1, 2, 4, 6, and 10 on word-, nonword-, and text-reading fluency. In Grades 1 and 4, they were also assessed on phonological awareness, rapid naming, phonological memory, orthographic knowledge, and articulation rate. Results of growth curve modeling showed that during the first developmental period, there was a rapid initial growth from Grade 1 to Grade 2 followed by a less rapid growth from Grade 2 to Grade 4. In the second developmental period, the slow growth continued. In both developmental periods, rapid naming and orthographic knowledge predicted the initial status of all reading outcomes and phonological memory predicted the initial status of nonword-reading fluency. Phonological awareness predicted the initial status of nonword-reading fluency in the first developmental period and the initial status of word- and text-reading fluency in the second developmental period. None of the cognitive skills predicted the growth rate in reading skills. Theoretical and practical implications of these findings are discussed.

Predicting the early growth of word and nonword reading fluency in a consistent syllabic orthography

BackgroundThe present study aimed to examine the early growth of word and nonword reading fluency and their cognitive predictors in a consistent syllabic orthography (Japanese Hiragana).MethodOne hundred sixty‐nine Grade 1 Japanese children (Mage = 80.12 months, SD = 3.62) were followed until the middle of Grade 2 and assessed four times on word and nonword reading fluency in Hiragana. Nonverbal IQ, vocabulary, phonological awareness, rapid automatized naming, phonological memory and morphological awareness were also assessed at the beginning of Grade 1.ResultsGrowth curve analysis showed that growth was faster in word reading than in nonword reading and the lexicality effect increased over time. Rapid automatized naming, phonological memory and morphological awareness were associated with the initial status and rate of growth in word and nonword reading. Furthermore, the initial status and the growth rates were highly correlated between word and nonword reading, even when the effects of the cognitive skills were controlled.ConclusionsThese findings suggest that, despite the remarkable differences in the growth trajectories of word and nonword reading fluency, they share at least a part of their underlying processes and develop closely in tandem during this period.

Cognitive predictors of word reading in Sinhala

We examined whether akshara knowledge, phonological awareness, phonological memory, and RAN predict variability in word and nonword reading skills in Grade 1–4 children (N = 200) learning to read Sinhala. Hierarchical regression analyses showed that akshara knowledge had the strongest unique association with both word and nonword reading accuracy across grades. Akshara knowledge and RAN predicted word and nonword reading fluency. The impact of phonological memory and syllable awareness on reading was mostly mediated by akshara knowledge, and phoneme awareness was not uniquely associated with word reading skills in any grade. These results suggest that there are multiple cognitive correlates of accurate and fluent word reading in Sinhala, and akshara knowledge is the most important predictor of learning to read words. The findings have implications for the literacy acquisition, development, and instruction in alphasyllabaries.

Phonics training for English-speaking poor readers.

The reading skills of 16% of children fall below the mean range for their age, and 5% of children have significant and severe reading problems. Phonics training is one of the most common reading treatments used with poor readers, particularly children. To measure the effect of phonics training and explore the impact of various factors, such as training duration and training group size, that might moderate the effect of phonics training on literacy-related skills in English-speaking poor readers. We searched CENTRAL, MEDLINE, Embase, 12 other databases, and three trials registers up to May 2018. We also searched reference lists of included studies and contacted experts in the field to identify additional studies. We included studies that used randomisation, quasi-randomisation, or minimisation to allocate participants to a phonics intervention group (phonics training only or phonics training plus one other literacy-related skill) or a control group (no training or non-literacy training). Participants were English-speaking poor readers with word reading one standard deviation below the appropriate level for their age (children, adolescents, and adults) or one grade or year below the appropriate level (children only), for no known reason. Participants had no known comorbid developmental disorder, or physical, neurological, or emotional problem. We used standard methodological procedures expected by Cochrane. We included 14 studies with 923 participants in this review. Studies took place in Australia, Canada, the UK, and the USA. Six of the 14 included studies were funded by government agencies and one was funded by a university grant. The rest were funded by charitable foundations or trusts. Each study compared phonics training alone, or in conjunction with one other reading-related skill, to either no training (i.e. treatment as usual) or alterative training (e.g. maths). Participants were English-speaking children or adolescents, of low and middle socioeconomic status, whose reading was one year, one grade, or one standard deviation below the level expected for their age or grade for no known reason. Phonics training varied between studies in intensity (up to four hours per week), duration (up to seven months), training group size (individual and small groups), and delivery (human and computer). We measured the effect of phonics training on seven primary outcomes (mixed/regular word reading accuracy, non-word reading accuracy, irregular word reading accuracy, mixed/regular word reading fluency, non-word reading fluency, reading comprehension, and spelling). We judged all studies to be at low risk of bias for most risk criteria, and used the GRADE approach to assess the quality of the evidence.There was low-quality evidence that phonics training may have improved poor readers' accuracy for reading real and novel words that follow the letter-sound rules (standardised mean difference (SMD) 0.51, 95% confidence interval (CI) 0.13 to 0.90; 11 studies, 701 participants), and their accuracy for reading words that did not follow these rules (SMD 0.67, 95% CI 0.26 to 1.07; 10 studies, 682 participants). There was moderate-quality evidence that phonics training probably improved English-speaking poor readers' fluency for reading words that followed the letter-sounds rules (SMD 0.45, 95% CI 0.19 to 0.72; 4 studies, 224 participants), and non-word reading fluency (SMD 0.39, 95% CI 0.10 to 0.68; 3 studies, 188 participants), as well as their accuracy for reading words that did not follow these rules (SMD 0.84, 95% CI 0.30 to 1.39; 4 studies, 294 participants). In addition, there was low-quality evidence that phonics training may have improved poor readers' spelling (SMD 0.47, 95% CI -0.07 to 1.01; 3 studies, 158 participants), but only slightly improve their reading comprehension (SMD 0.28, 95% CI -0.07 to 0.62; 5 studies, 343 participants). Phonics training appears to be effective for improving literacy-related skills, particularly reading fluency of words and non-words, and accuracy of reading irregular words. More studies are needed to improve the precision of outcomes, including word and non-word reading accuracy, reading comprehension, spelling, letter-sound knowledge, and phonological output. More data are also needed to determine if phonics training in English-speaking poor readers is moderated by factors such as training type, intensity, duration, group size, or administrator.

Is Morphological Awareness a Relevant Predictor of Reading Fluency and Comprehension? New Evidence From Italian Monolingual and Arabic-Italian Bilingual Children

In the current study we examined the contribution of morphological awareness to reading competence in a group of Italian L1 and Arabic-Italian early L2 children, i.e., exposed to Italian before 3 years of age. Children from first to fifth grade (age range: 6 to 11 years old) were tested on a range of morphological awareness and lexical tasks. Reading ability was tested through standardized tests of reading fluency and comprehension. Results showed that L1 children outperformed L2 on every measure of morphological awareness, as well as on reading tests. Regression analyses revealed that morphological awareness contributed to a different extent to reading ability across groups. Accuracy in the morphological awareness tasks was a significant predictor of word (and non-word) reading fluency in L1 and L2 first and second graders, while only in L1 third to fifth graders, response times and accuracy to a morphological awareness task explained a unique amount of variance in reading comprehension. Our results highlight the critical role of morphological processing in reading efficiency and suggest that a training inspired by morphological awareness may improve reading skills also in bilingual students.

Association analysis of dyslexia candidate genes in a Dutch longitudinal sample.

Dyslexia is a common specific learning disability with a substantive genetic component. Several candidate genes have been proposed to be implicated in dyslexia susceptibility, such as DYX1C1, ROBO1, KIAA0319, and DCDC2. Associations with variants in these genes have also been reported with a variety of psychometric measures tapping into the underlying processes that might be impaired in dyslexic people. In this study, we first conducted a literature review to select single nucleotide polymorphisms (SNPs) in dyslexia candidate genes that had been repeatedly implicated across studies. We then assessed the SNPs for association in the richly phenotyped longitudinal data set from the Dutch Dyslexia Program. We tested for association with several quantitative traits, including word and nonword reading fluency, rapid naming, phoneme deletion, and nonword repetition. In this, we took advantage of the longitudinal nature of the sample to examine if associations were stable across four educational time-points (from 7 to 12 years). Two SNPs in the KIAA0319 gene were nominally associated with rapid naming, and these associations were stable across different ages. Genetic association analysis with complex cognitive traits can be enriched through the use of longitudinal information on trait development.

Evaluation of results from genome-wide studies of language and reading in a novel independent dataset.

Recent genome-wide association scans (GWAS) for reading and language abilities have pin-pointed promising new candidate loci. However, the potential contributions of these loci remain to be validated. In this study, we tested 17 of the most significantly associated single nucleotide polymorphisms (SNPs) from these GWAS studies (P < 10(-6) in the original studies) in a new independent population dataset from the Netherlands: known as Familial Influences on Literacy Abilities. This dataset comprised 483 children from 307 nuclear families and 505 adults (including parents of participating children), and provided adequate statistical power to detect the effects that were previously reported. The following measures of reading and language performance were collected: word reading fluency, nonword reading fluency, phonological awareness and rapid automatized naming. Two SNPs (rs12636438 and rs7187223) were associated with performance in multivariate and univariate testing, but these did not remain significant after correction for multiple testing. Another SNP (rs482700) was only nominally associated in the multivariate test. For the rest of the SNPs, we did not find supportive evidence of association. The findings may reflect differences between our study and the previous investigations with respect to the language of testing, the exact tests used and the recruitment criteria. Alternatively, most of the prior reported associations may have been false positives. A larger scale GWAS meta-analysis than those previously performed will likely be required to obtain robust insights into the genomic architecture underlying reading and language.

Replicability of sight word training and phonics training in poor readers: a randomised controlled trial.

Given the importance of effective treatments for children with reading impairment, paired with growing concern about the lack of scientific replication in psychological science, the aim of this study was to replicate a quasi-randomised trial of sight word and phonics training using a randomised controlled trial (RCT) design. One group of poor readers (N = 41) did 8 weeks of phonics training (i.e., phonological decoding) and then 8 weeks of sight word training (i.e., whole-word recognition). A second group did the reverse order of training. Sight word and phonics training each had a large and significant valid treatment effect on trained irregular words and word reading fluency. In addition, combined sight word and phonics training had a moderate and significant valid treatment effect on nonword reading accuracy and fluency. These findings demonstrate the reliability of both phonics and sight word training in treating poor readers in an era where the importance of scientific reliability is under close scrutiny.

Sight Word and Phonics Training in Children With Dyslexia

The aims of this study were to (a) compare sight word training and phonics training in children with dyslexia, and (b) determine if different orders of sight word and phonics training have different effects on the reading skills of children with dyslexia. One group of children (n = 36) did 8 weeks of phonics training (reading via grapheme–phoneme correspondence rules) and then 8 weeks of sight word training (reading irregular words as a whole), one group did the reverse (n = 36), and one group did phonics and sight word training simultaneously for two 8-week periods (n = 32). We measured the effects of phonics and sight word training on sight word reading (trained irregular word reading accuracy, untrained irregular word reading accuracy), phonics reading (nonword reading accuracy, nonword reading fluency), and general reading (word reading fluency, reading comprehension). Sight word training led to significant gains in sight word reading measures that were larger than gains made from phonics training, phonics training led to statistically significant gains in a phonics reading measure that were larger than gains made from sight word training, and both types of training led to significant gains in general reading that were similar in size. Training phonics before sight words had a slight advantage over the reverse order. We discuss the clinical implications of these findings for improving the treatment and assessment of children with dyslexia.

What's in a Name Depends on the Type of Name: The Relationships Between Semantic and Phonological Access, Reading Fluency, and Reading Comprehension

The present study investigated the relationships between lexical access, reading fluency, and comprehension. Two components of speed of lexical access were studied: phonological and semantic. Previous studies have mainly investigated these components of lexical access separately. The present study examined both components in naming tasks—with isolated letters (phonological) and pictures (semantic). Seventy-five Grade 5 students were administered measures of letter and picture naming speed, word and nonword reading fluency, and reading comprehension, together with control measures of vocabulary. The results showed that letter naming was a unique predictor of word reading fluency, whereas picture naming was not. Conversely, picture naming speed contributed unique variance to reading comprehension, whereas letter naming did not. The results indicate that phonological and semantic lexical access speed are separable components that are important for different reading subskills.

Phonics training for English-speaking poor readers

Around 5% of English speakers have a significant problem with learning to read words. Poor word readers are often trained to use letter-sound rules to improve their reading skills. This training is commonly called phonics. Well over 100 studies have administered some form of phonics training to poor word readers. However, there are surprisingly few systematic reviews or meta-analyses of these studies. The most well-known review was done by the National Reading Panel (Ehri 2001) 12 years ago and needs updating. The most recent review (Suggate 2010) focused solely on children and did not include unpublished studies. The primary aim of this review was to measure the effect that phonics training has on the literacy skills of English-speaking children, adolescents, and adults whose reading was at least one standard deviation (SD), one year, or one grade below the expected level, despite no reported problems that could explain their impaired ability to learn to read. A secondary objective was to explore the impact of various factors, such as length of training or training group size, that might moderate the effect of phonics training on poor word reading skills. We searched the following databases in July 2012: CENTRAL 2012 (Issue 6), MEDLINE 1948 to June week 3 2012, EMBASE 1980 to 2012 week 26, DARE 2013 (Issue 6), ERIC (1966 to current), PsycINFO (1806 to current), CINAHL (1938 to current), Science Citation Index (1970 to 29 June 2012), Social Science Citation Index (1970 to 29 June 2012), Conference Proceedings Citation Index - Science (1990 to 29 June 2012), Conference Proceedings Citation Index - Social Science & Humanities (1990 to 29 June 2012), ZETOC, Index to Theses-UK and Ireland, ClinicalTrials.gov, ICTRP, the metaRegister of Controlled Trials, ProQuest Dissertations and Theses, DART Europe E-theses Portal, Australasian Digital Theses Program, Education Research Theses, Electronic Theses Online System, Networked Digital Library of Theses and Dissertations. Theses Canada portal, www.dissertation.com, and www.thesisabstracts.com. We also contacted experts and examined the reference lists of published studies. We included studies that use randomisation, quasi-randomisation, or minimisation to allocate participants to either a phonics intervention group (phonics alone, phonics and phoneme awareness training, or phonics and irregular word reading training) or a control group (no training or alternative training, such as maths). Participants were English-speaking children, adolescents, or adults whose word reading was below the level expected for their age for no known reason (that is, they had adequate attention and no known physical, neurological, or psychological problems). Two review authors independently selected studies, assessed risk of bias, and extracted data. We found 11 studies that met the criteria for this review. They involved 736 participants. We measured the effect of phonics training on eight outcomes. The amount of evidence for each outcome varied considerably, ranging from 10 studies for word reading accuracy to one study for nonword reading fluency. The effect sizes for the outcomes were: word reading accuracy standardised mean difference (SMD) 0.47 (95% confidence interval (CI) 0.06 to 0.88; 10 studies), nonword reading accuracy SMD 0.76 (95% CI 0.25 to 1.27; eight studies), word reading fluency SMD -0.51 (95% CI -1.14 to 0.13; two studies), reading comprehension SMD 0.14 (95% CI -0.46 to 0.74; three studies), spelling SMD 0.36 (95% CI -0.27 to 1.00; two studies), letter-sound knowledge SMD 0.35 (95% CI 0.04 to 0.65; three studies), and phonological output SMD 0.38 (95% -0.04 to 0.80; four studies). There was one result in a negative direction for nonword reading fluency SMD 0.38 (95% CI -0.55 to 1.32; one study), though this was not statistically significant.We did five subgroup analyses on two outcomes that had sufficient data (word reading accuracy and nonword reading accuracy). The efficacy of phonics training was not moderated significantly by training type (phonics alone versus phonics and phoneme awareness versus phonics and irregular word training), training intensity (less than two hours per week versus at least two hours per week), training duration (less than three months versus at least three months), training group size (one-on-one versus small group training), or training administrator (human administration versus computer administration). Phonics training appears to be effective for improving some reading skills. Specifically, statistically significant effects were found for nonword reading accuracy (large effect), word reading accuracy (moderate effect), and letter-sound knowledge (small-to-moderate effect). For several other outcomes, there were small or moderate effect sizes that did not reach statistical significance but may be meaningful: word reading fluency, spelling, phonological output, and reading comprehension. The effect for nonword reading fluency, which was measured in only one study, was in a negative direction, but this was not statistically significant.Future studies of phonics training need to improve the reporting of procedures used for random sequence generation, allocation concealment, and blinding of participants, personnel, and outcome assessment.

The effect of a multicomponent literacy instruction model on literacy growth for kindergartners and first‐grade students in Chile

In the present study we examined the impact of a comprehensive literacy instruction model called Collaborative Language and Literacy Instruction Project (CLLIP) on language and literacy achievement over the course of a year by Spanish-speaking children in Chile. Participants included kindergartners (N = 312) from high and low socioeconomic backgrounds and first-grade students (N = 305) from high SES families. The CLLIP model targeted phonological awareness, alphabetics and phonics, fluency, vocabulary, reading comprehension and writing, and included coaching and sustained follow-up as key elements for teacher professional development. The results showed promise for the CLLIP model in the Chilean context. Kindergartners in CLLIP classrooms had faster growth rates in letter naming, word reading, vocabulary, and phonemic segmentation fluency than those in control classrooms, and had higher scores at the end of the year in phonemic segmentation fluency, letter naming, and word reading. In addition, kindergartners from high SES families had faster growth rates than kindergartners from low SES families in letter naming and word reading. Effect sizes ranged from small (d = .18 in word reading) to fairly large (d = .70 in letter-naming fluency). First-grade students in CLLIP classrooms had faster growth rates than students in control classrooms in vocabulary, nonword reading fluency, word reading, and reading comprehension. Effect sizes were small in vocabulary, nonword reading fluency, and reading comprehension (.23 ≤ d ≤ .28) and medium in word reading (d = .50). These results suggest that the present multicomponent literacy instructional model had a positive impact on Chilean children's literacy acquisition.

Predictors of Word and Non-word Reading Fluency:A Cross-Sectional Study

Predictors of Word and Non-word Reading Fluency:A Cross-Sectional Study

Is a cerebellar deficit the underlying cause of reading disabilities?

This study investigated whether children with dyslexia differed in their performance on reading, phonological, rapid naming, motor, and cerebellar-related tasks and automaticity measures compared to reading age (RA)-matched and chronological age (CA)-matched control groups. Participants were 51 children attending mainstream English elementary schools in Quebec. All participants completed measures of IQ, word and nonword reading fluency, elision, nonword decoding, rapid naming, bead threading, peg moving, toe tapping, postural stability, and muscle tone. Results from both group contrasts and analyses at the individual case level did not provide support for claims of motor-cerebellar involvement in either typical or atypical reading acquisition. Results were more consistent with a phonological core process account of both typical reading and reading difficulty. Phonological deficits for children with dyslexia compared to RA-matched controls were, however, only evident in group contrasts. Findings thus also have important implications for identifying at-risk readers among their same-aged peers.

Contributions of phonological processing skills to reading skills in Arabic speaking children

This cross-sectional study investigated contributions of phonological awareness (Elision and blending), rapid naming (object, color, letter, and digit), and phonological memory (nonword repetition and Digit Span) to basic decoding and fluency skills in Arabic. Participants were 237 Arabic speaking children from Grades K-3. Dependent measures included word decoding, oral passage reading fluency, nonword reading fluency, and retell fluency. Within-grade analyses indicated that phonological awareness accounted for more variance than rapid naming regardless of the nature of the outcome measure and grade. Rapid naming’s capacity to predict variance, while less than that of phonological awareness, tended to rise steadily and was highest in Grade 3. Phonological memory, as measured by this study’s tasks, showed almost no relationship to reading performance. The findings are discussed with respect to changing the requirements of Arabic reading in Grades K-3 and suggestions are made for future research.

Longitudinal predictors of reading and spelling across languages varying in orthographic consistency

We examined the longitudinal predictors of nonword decoding, reading fluency, and spelling in three languages that vary in orthographic depth: Finnish, Greek, and English. Eighty-two English-speaking, 70 Greek, and 88 Finnish children were followed from the age of 5.5 years old until Grade 2. Prior to any reading instruction, they were administered measures of phonological awareness, letter knowledge, and rapid naming speed. In Grade 2, they were administered measures of nonword decoding, text-reading fluency, and spelling. The results showed that the model for nonword decoding in Greek was similar to that of Finnish (both have consistent grapheme-to-phoneme mappings) while the model for spelling in Greek was similar to that of English (both have some inconsistent phoneme-to-grapheme mappings). In addition, the models for nonword decoding and spelling in Finnish were similar, because Finnish is consistent in both directions. Letter knowledge dominated the prediction in each language. The predictable role of orthographic consistency on literacy acquisition is discussed.

‘Mind the Gap’: Effective Literacy Instruction for Indigenous Low-Progress Readers

AbstractA large gap is evident between the reading and related skills performance of Aboriginal students compared with that of their nonindigenous peers and this gap increases over the primary years of schooling. In this study, 34 students attended a tutorial centre in Sydney for older low-progress readers in Years 5 and 6, for two school terms. All students were referred by their schools on the basis of their reading difficulty and low socioeconomic status. The parents of 14 of these students self-identified as being Aboriginal. All students received an intensive, systematic skills-based remedial reading and spelling program (mornings only) and were assessed on a battery of literacy measures both prior to and following the two term intervention. The pre and posttest raw scores on all measures were analysed to determine the efficacy of the program. The group as a whole made large and highly significant gains on all measures of reading accuracy, comprehension, single word reading, nonword reading, spelling and oral reading fluency. There were no significant differences in gain between the two subgroups indicating that the program of instruction was equally beneficial for both Aboriginal and non-Aboriginal students.
