The Universal and the unique in dyslexia: A cross-linguistic investigation of reading and reading fluency in Hebrew-and English-speaking children with reading disorders

Cross-linguistic studies provide a unique tool for the identification of universal processes in oral and written language, both in development and in breakdown (Annual Review of psychology, 52, 369–396). Examining the differential strengths and weaknesses of children with dyslexia in contrasting orthographies can help illumine both the more universal aspects of reading disabilities, as well as their individual language-specific attributes. The aim of this study, was to investigate the shared and distinctive characteristics of readers with dyslexia on reading and reading fluency across Hebrew and English orthographies. Differences between 60 Hebrew and English-speaking children with dyslexia on a battery of cognitive, linguistic, and reading measures will be discussed along with theoretical implications.     

Oral reading fluency,reading motivation and reading comprehension among second graders

The relationships between oral reading fluency, reading motivation and reading comprehension were examined at the beginning and the end of second grade among 121 Hebrew speaking students. The contribution of oral reading fluency and three sub-factors of motivation—self-concept as a reader, value attached to reading and literacy outloud (social interactions about literacy)—at the beginning of the school year to reading comprehension at the end of the year was also examined. Results indicate that all oral reading fluency measures and all motivational sub-factors were significantly correlated with reading comprehension at the end of second grade. In addition, positive change in self-concept as a reader along the school year was related to improvement in reading achievement. Finally, text rate and self-concept as a reader at the beginning of second grade together predicted 28% of the variance in reading comprehension at the end of second grade. The results support the notion that the cognitive approach to reading cannot explain all the variance in reading comprehension and emphasize the necessity of including motivational factors in the language arts curriculum in the early stages of reading acquisition.

     

Toward modeling reading comprehension and reading fluency in English language learners

This study investigated the adequacy of an expanded simple view of reading (SVR) framework for English language learners (ELLs), using mediation modeling approach. The proposed expanded SVR included reading fluency as an outcome and phonological awareness and naming speed as predictors. To test the fit of the proposed mediation model, longitudinal data from 308 ELLs from different linguistic backgrounds were analyzed using structural equation modeling. We examined the mediating role of Grade 2 word-level reading skills in the association between Grade 1 phonological awareness, naming speed, and listening comprehension and Grade 3 reading comprehension and reading fluency. The results indicated that word-level reading skills fully mediated the association between phonological awareness, reading comprehension and reading fluency. Word-level reading skills partially mediated the association between naming speed and reading fluency. Listening comprehension contributed directly to reading comprehension and reading fluency. It appears that reading development in ELLs is better understood when reading fluency is added to the SVR framework as an outcome and naming speed as a building block of SVR. Theoretical aspects of the mediation model in relation to ELL reading development are also addressed.     

Word reading fluency: A transfer appropriate processing accountof fluency transfer

Word reading fluency, as indexed by the fast and accurate identification of single words, predicts both general reading ability and reading comprehension. This study compared the effects of context training and isolated word training on subsequent measures of word reading fluency. Good and poor readers were given 12 repetitions of two sets of words; 48 new words were learned in each condition. Words were presented in a story during context training and on a computer screen during isolated word training. Target words were read in isolation at test, randomly displayed within a series containing 72 untrained words. Results show that words trained in isolation are remembered longer and read faster when presented in isolation at test compared to words trained in context. Theoretical implications are discussed in relation to transfer appropriate processing.     

Enhancing narrative and reading fluency while becoming storyers

Storytelling has many values in the classroom setting, even though it is often given a low priority. Here Catherine Wildish recounts her experience of trying to develop children’s abilities to story and suggests that this has a great deal of value in developing their reading and writing.     

An emergent interaction between reading fluency and vocabulary in the prediction of reading comprehension among French immersion elementary students

This study investigated an emergent interaction between word reading fluency and vocabulary knowledge in the prediction of reading comprehension among French immersion students in Grades 2 and 3. A group of 66 students were tested on measures of phonological awareness, rapid automatized naming, word reading accuracy, vocabulary, word reading fluency and reading comprehension in English and French at both time points. Hierarchical regression analyses were conducted to examine whether vocabulary and word reading fluency interact in predicting English and French reading comprehension. Regressions were constructed for each language and grade separately. Results showed that in Grade 2, word reading fluency and vocabulary contributed independently to reading comprehension, though an interaction between these variables was not observed in either language. By Grade 3, an interaction between these constructs emerged and was shown to predict reading comprehension in both English and French. Specifically, vocabulary was positively related to reading comprehension among students with moderate to high levels of fluency, while vocabulary did not uniquely contribute to reading comprehension among those who were less fluent. The emergence of an interaction in Grade 3 suggests that as students’ reading skills become more proficient, reading comprehension outcomes are better explained by taking into account the interaction between reading fluency and vocabulary knowledge.

Patterns of inverted reading and subgroups in dyslexia

Reading performance of 46 poor readers was compared with that of 20 normal control readers. All subjects were second grade children. In Experiment 1 two matching word lists were presented under two conditions: one version of the test was read in the upright position and the other inverted. In Experiment 2 the eye movements of all subjects were recorded during reading of two meaningful sentences in the normal and inverted position. While the controls were negatively influenced by inversion of the text, the poor readers showed a variety of responses. Overall, the poor readers showed a slight tendency to be better at reading in the inverted position when the text must be scanned from right to left. An individual analysis of the data revealed that in 28.3% of the poor readers inverted reading improved performance at least 15 %, a phenomenon found in none of the controls.     

Direct and indirect effects of print exposure on silent reading fluency

Print exposure is an important causal factor in reading development. Little is known, however, of the mechanisms through which print exposure exerts an effect onto reading. To address this gap, we examined the direct and indirect effects of print exposure on silent reading fluency among college students (n = 52). More specifically, we focused on phonetic decoding and sight word reading efficiency as potential mediators of the indirect effects of print exposure on silent reading fluency. Silent reading fluency was chosen as the outcome given that the natural reading experience occurs predominately in the silent mode. Results showed that the direct effect of print exposure on silent reading fluency was significant. Sight word reading efficiency partially mediated the indirect effect of print exposure on silent reading fluency. Phonetic decoding efficiency also partially mediated the indirect effect of print exposure on silent reading fluency, but only when followed by sight word reading efficiency to form a serial and joint mechanism (i.e., print exposure → phonetic decoding → sight word reading → silent reading fluency). Present findings highlight two mechanisms through which print exposure exerts an effect onto silent reading fluency, both of which involve sight word reading efficiency.     

Spelling errors and reading fluency in compensated adult dyslexics

Generally, a person who is diagnosed as dyslexic remains diagnosably dyslexic all his/her life. However, occasionally, an individual compensates for his/her difficulties in some way, and by adulthood is no longer diagnosably dyslexic. In what ways are these compensated dyslexics different from both dyslexics and nondyslexics? We compared IQ, achievement test, and spelling error scores in adult dyslexics, adult nondyslexics, and adult compensated dyslexics (N=25) in the two studies reported here. The second study differed from the first in that the subjects were matched for age, education, IQ, and SES. In both studies, compensateds were significantly different from nondyslexics on the WRAT Spelling subtest and Reading Quotient scores. In the second study the compensateds differed from the nondyslexics in total raw score and average reading speed on Gray Oral Reading Test. On the other hand, they were different from dyslexics on all reading and spelling variables in both studies, except for PIAT Reading Comprehension in Study 2. Finally, in Study 2, the compensateds were different from both dyslexics and nondyslexics in average reading speed. In conclusion, it appears that compensation does not result from differences in IQ, education, or SES, though it may be influenced to some extent by sex. Compensateds appear very similar to nondyslexics in their reading and spelling skills; however, there appears to be a difference in the automaticity with which they apply these skills.     

The impact of environmental factors on components of reading and dyslexia

Data from 123 male adults were analyzed to estimate environmental influences on components of literacy skills and to explore the impact of environmental factors in different approaches to define reading difficulty. Literacy skills were decomposed into general cognitive function, reading comprehension, spelling, word reading, and phonological ability. Environmental factors examined were related to home conditions, school conditions, and literacy environment. Results suggest that there is a substantial social-cultural bias in the delineation of literacy skills and in the definitions of reading disabilities. Results also suggest that phonological ability constitutes the only measure relatively unaffected by environmental influences. This study has brought forward a new argument for emphasizing phonological deficits as the core component in defining dyslexia.

Effects of self-monitoring training on reading accuracy and fluency of poor readers

The effect of the self-monitoring training on reading accuracy and fluency of second-grade poor readers was examined. The participants were assigned in one experimental and three control groups. The experimental group was reinforced with token-economy for self-correction and fluent reading. One control group practiced reading without feedback, the second one practiced the calculation of simple arithmetic tasks, and the third one received no training at all. The improvement in reading accuracy was obtained only in the self-monitoring group, and remained for five months. However, the improvement in reading fluency was obtained in the two reading groups, but only the self-monitoring group showed further improvement during five months after training. The results confirmed the importance of self-monitoring already at the level of lexical access in reading and that of local text comprehension.     

Specificity and overlap in skills underpinning reading and arithmetical fluency

The aim of this study was to examine unique and common causes of problems in reading and arithmetic fluency. 13- to 14-year-old students were placed into one of five groups: reading disabled (RD, n = 16), arithmetic disabled (AD, n = 34), reading and arithmetic disabled (RAD, n = 17), reading, arithmetic, and listening comprehension disabled (TRIPLE, n = 9), and typically developing students (NON-LD, n = 40). Multivariate analyses of covariance and variance component analyses showed that reading problems are characterised by difficulties with phonological processing and with rapid automatic naming. Problems with executive functioning and with digit span were typical for students with arithmetical fluency difficulties. RAD students had problems with phonological processing, rapid naming, executive functioning, and digit span. Impairments in number fact fluency, digit span, loudness perception, speeded sound manipulation, and coding, which all share a fluency component were common to problems with reading and arithmetical fluency.     

The effect of print size on reading speed in dyslexia

This article details a study which predicted that across a wide range of print sizes dyslexic reading would follow the same curve shape as skilled reading, with constant reading rates across large print sizes and a sharp decline in reading rates below a critical print size. It also predicted that dyslexic readers would require larger critical print sizes to attain their maximum reading speeds, following the letter position coding deficit hypothesis. Reading speed was measured across twelve print sizes ranging from Snellen equivalents of 20/12 to 20/200 letter sizes for a group of dyslexic readers in Grades 2 to 4 (aged 7 to 10 years), and for non-dyslexic readers in Grades 1 to 3 (aged 6 to 8 years). The groups were equated for word reading ability. Results confirmed that reading rate-by-print size curves followed the same two-limbed shape for dyslexic and non-dyslexic readers. Dyslexic reading curves showed higher critical print sizes and shallower reading rate-by-print size slopes below the critical print size, consistent with the hypothesis of a letter-position coding deficit. Non-dyslexic reading curves also showed a decrease of critical print size with age. A developmental lag model of dyslexic reading does not account for the results, since the regression of critical print size on maximum reading rate differed between groups.     

Examining the effects of PASS cognitive processes on Chinese reading accuracy and fluency

The purpose of this study was to examine the contribution of PASS (Planning, Attention, Simultaneous, and Successive) processes to Chinese reading accuracy and fluency. One-hundred-forty Grade 3 to 5 Mandarin-speaking children were assessed on measures of PASS processes, phonological awareness, and orthographic knowledge. A year later they were assessed on reading accuracy and fluency. The results indicated that successive processing predicted reading through the effects of phonological awareness and simultaneous processing predicted reading through the effects of orthographic knowledge. The results were similar for reading accuracy and fluency. Implications for the PASS theory are discussed.     

Reading development in European Portuguese: relationships between oral reading fluency,vocabulary and reading comprehension

This study investigated direct and indirect effects between oral reading fluency, vocabulary and reading comprehension across reading development in European Portuguese. Participants were 329 children attending basic education, from grade 1 to grade 6. The results of path analyses showed that text reading fluency is much more dependent on the foundational skills of word recognition than reading comprehension, and the later, in turn, depends crucially on the specific constituent skill of text reading fluency. Text reading fluency has a significant influence on vocabulary from the beginning, but vocabulary contributed to reading comprehension only in more advanced grades. These results, obtained with an orthography of intermediate depth, are in line with the Simple View of Reading (SVR). However, they also highlight the importance of textual cues—besides the pivotal role of decoding—from the beginning of learning to read, which must be taken into account in the SVR.     

Rapid automatized naming,word-level reading,and oral reading fluency in first-grade Korean readers at risk for reading difficulties

This study was designed to investigate potential reading differences between low-achieving and typically achieving first-grade Korean-speaking children by (1) comparing their speed of lexical access on alphanumeric and non-alphanumeric tests of rapid automatized naming and (2) comparing relationships between the two groups’ performance on alphanumeric and non-alphanumeric tasks with their performance on component measures of reading. Twenty-seven low-achieving readers and 34 typically achieving readers participated in this study. The low-achieving readers performed significantly more slowly than their typically achieving reading peers on the four measures of rapid naming. The response rates for both alphanumeric naming tasks (digits and letters) showed strong negative correlations with oral reading fluency, while their response rates for the non-alphanumeric naming tasks (Color and Object naming) showed relatively weak relationships with reading measures for both groups. In regression equations, Letter naming tasks were uniquely associated with both word recognition and oral reading fluency. The utility of using alphanumeric naming tasks as indicators for identifying Korean Hangul readers who are at risk for reading disabilities is discussed.     

Effects of fluency, oral language, and executive function on reading comprehension performance

Reading disability (RD) typically consists of deficits in word reading accuracy and/or reading comprehension. While it is well known that word reading accuracy deficits lead to comprehension deficits (general reading disability, GRD), less is understood about neuropsychological profiles of children who exhibit adequate word reading accuracy but nevertheless develop specific reading comprehension deficits (S-RCD). Establishing the underlying neuropsychological processes associated with different RD types is essential for ultimately understanding core neurobiological bases of reading comprehension. To this end, the present study investigated isolated and contextual word fluency, oral language, and executive function on reading comprehension performance in 56 9- to 14-year-old children [21 typically developing (TD), 18 GRD, and 17 S-RCD]. Results indicated that TD and S-RCD participants read isolated words at a faster rate than participants with GRD; however, both RD groups had contextual word fluency and oral language weaknesses. Additionally, S-RCD participants showed prominent weaknesses in executive function. Implications for understanding the neuropsychological bases for reading comprehension are discussed.
