Gender ratio and cognitive profiles in dyslexia: a cross-national study

The purpose of this study was to analyze possible gender-related differences in the prevalence of dyslexia. A cross-national comparison of Spain and Guatemala was conducted. Both countries speak the same language but have a different standard of living and educational level. A second purpose of this study was to analyze the cognitive profile of Guatemalan and Spanish males and females children with dyslexia. The log-linear analysis indicated that the number of dyslexics detected was different across the countries but there were no differences as a function of gender. Similarly, there were no significant or meaningful differences between dyslexic males and females in the cognitive processes involved in reading. Therefore, gender differences do not appear to be characteristic of developmental dyslexia.     

Learning Disabilities in Taiwan: A Case of Cultural Constraints on the Education of Students with Disabilities

Learning disabilities (LD) has been recognized as a category of special education in Taiwanese law since 1984, and policies ensure educational services for children and youth who have LD. The official definition and identification criteria established in Taiwan's laws closely correspond with those of the United States, but practice differs, largely influenced by the people's cultural and linguistic background. I discuss these legal and cultural features as well as other matters (e.g., growth and change in professional literature on LD). Compared to economically developed countries such as the United States, the educators in Taiwan implement identification procedures, placement, and services at a lower cost. Contents of implementation are introduced in detail. The prevalence rate of LD has been very low (<1 percent). I examine culture‐ and/or society‐specific reasons for low prevalence, such as Chinese orthography, regular teachers' compliance with referral procedures, the education‐first belief of parents, and problems with identification procedures.     

Speech recognition-based and automaticity programs to help students with severe reading and spelling problems

This study was conducted to assess the effectiveness of two programs developed by the Frostig Center Research Department to improve the reading and spelling of students with learning disabilities (LD): a computer Speech Recognition-based Program (SRBP) and a computer and text-based Automaticity Program (AP). Twenty-eight LD students with reading and spelling difficulties (aged 8 to 18) received each program for 17 weeks and were compared with 16 students in a contrast group who did not receive either program. After adjusting for age and IQ, both the SRBP and AP groups showed significant differences over the contrast group in improving word recognition and reading comprehension. Neither program showed significant differences over contrasts in spelling. The SRBP also improved the performance of the target group when compared with the contrast group on phonological elision and nonword reading efficiency tasks. The AP showed significant differences in all process and reading efficiency measures.     

Strategic Keyboard Training and Spelling Improvement among Children with Learning Disabilities and Mental Retardation

The aim of the study was to investigate the effectiveness of a strategic keyboard training program for improving the spelling performance of children with mild disabilities. The sample consisted of 36 mildly disabled students divided into two groups: 18 learning disabled students, and 18 educable mentally retarded students. The teachers used strategic procedures emphasising awareness of word structure and spelling strategies, combined with keyboard training, for a duration of three months (45‐minute sessions, twice weekly). The results demonstrated a significant decrease in spelling errors, as assessed through computer typing and handwriting. However, the comparisons between the group achievements of the learning disabled and mentally retarded children did not reveal significant differences in the development of the spelling performance. Analysis of the results, and of the four case‐studies, pin‐pointed attention onto the initial individual differences in the spelling performance, and onto the students’ individual learning style during training, emphasising the need for an individualised approach in remedial computerised spelling procedures.     

The relationship between IQ and reading disabilities in English-speaking Canadian and Spanish children

This study was designed to examine the role of intelligence (IQ) in the definition of reading disabilities (RD) in languages with different orthographic systems. A sample of 94 Spanish children and 157 English-speaking Canadian children with RD was classified into four groups on the basis of IQ scores from the Wechsler Intelligence Scale for Children-Revised (< 80; 81-90; 91-109; 110-140). We examined the reading and spelling skills of Canadian and Spanish children as a function of Full Scale, Verbal, and Performance IQ scores. Significant differences between the languages were found when reading performance was analyzed as a function of Verbal IQ scores, in that there were some differences between the groups of Canadian children with RD but not between the groups of Spanish children. The Canadian children with Verbal IQ scores < 80 demonstrated relatively lower performance in reading and spelling skills than the Canadian groups with higher IQ scores. There were differences in reading tasks as a function of Performance IQ in English but not in Spanish. The differences in the role of IQ as a function of orthographic systems may relate to the greater significance of visual-orthographic as opposed to phonological processing in English.     

Prevalence of combined reading and arithmetic disabilities

This study assesses the prevalence of combined reading and arithmetic disabilities in 799 Dutch schoolchildren using st dardized school achievement tests. Scores of arithmetic, word recognition, reading comprehension, and spelling of child in fourth and fifth grade were used. The main interest involved the co-occurrence of word recognition and arithmetic d abilities because of their possible relationship. The authors find a percentage of 7.6 for combined reading and arithme disabilities. Reading disabilities and arithmetic disabilities co-occurred more often than expected based on rates of the s arate conditions. Children with combined reading and arithmetic disabilities seem to have more generalized achievem difficulties than single-deficit groups. Different operationalizations for reading disabilities (spelling and reading comp hension measures instead of word recognition) led, in part, to selection of other children. This might imply that differ processes underlie the relationship between arithmetic and word recognition disabilities compared to the relationship arithmetic disabilities with difficulties in spelling and reading comprehension.     

Preschool cognitive and language skills predicting Kindergarten and Grade 1 reading and spelling: a cross‐linguistic comparison

The importance of cognitive and language skills on reading and spelling development were investigated in a cross‐linguistic longitudinal study of 737 English‐speaking children (US/Australia) and 169 Scandinavian children (Norway/Sweden) from preschool to Kindergarten and Grade 1. The results revealed that phonological awareness and print knowledge were the strongest predictors of early reading and spelling across orthographies. The contribution from rapid naming to literacy development was low in Kindergarten, but similar to that of phonological awareness and print knowledge in Grade 1. The present study identified a significant difference across orthographies in the effects of print knowledge and general verbal ability on spelling in Kindergarten. However, this pattern was explained by cultural rather than orthographic differences. The results indicate that cognitive and language skills underlying early reading and spelling development are similar across alphabetic orthographies.     

A synthesis of spelling and reading interventions and their effects on the spelling outcomes of students with LD

Previous research studies examining the effects of spelling and reading interventions on the spelling outcomes of students with learning disabilities (LD) are synthesized. An extensive search of the professional literature between 1995 and 2003 yielded a total of 19 intervention studies that provided spelling and reading interventions to students with LD and measured spelling outcomes. Findings revealed that spelling outcomes were consistently improved following spelling interventions that included explicit instruction with multiple practice opportunities and immediate corrective feedback after the word was misspelled. Furthermore, evidence from spelling interventions that employed assistive technology aimed at spelling in written compositions indicated positive effects on spelling outcomes.     

Cognitive Profile of Neurofibromatosis Type 1: Rethinking Nonverbal Learning Disabilities

The cognitive profiles of children with Neurofibromatosis Type 1 (NF‐1) have many similarities to those observed in learning disabilities in the general school population, as well as some distinct features. Approximately 30–65 percent of children with NF‐1 have learning disabilities; most commonly, they have language and reading disabilities, along with motor, visuomotor, and visuospatial deficits. Similar to learning disabilities in the general population, approximately 50 percent of children with NF‐1 have Attention Deficit Hyperactivity Disorder (ADHD). In this article, the genetic and physical characteristics, the diagnostic criteria of NF‐1, and the cognitive profile of children with NF‐1 (including relationships between neurological abnormalities and cognition) are reviewed. Additionally, the types of educational interventions that would be indicated for children with NF‐1 are discussed.     

Psychometric stability of nationally normed and experimental decoding and related measures in children with reading disability

Achievement and cognitive tests are used extensively in the diagnosis and educational placement of children with reading disabilities (RD). Moreover, research on scholastic interventions often requires repeat testing and information on practice effects. Little is known, however, about the test-retest and other psychometric properties of many commonly used measures within the beginning reader population, nor are these nationally normed or experimental measures comparatively evaluated. This study examined the test-retest reliability, practice effects, and relations among a number of nationally normed measures of word identification and spelling and experimental measures of achievement and reading-related cognitive processing tests in young children with significant RD. Reliability was adequate for most tests, although lower than might be ideal on a few measures when there was a lengthy test-retest interval or with the reduced behavioral variability that can be seen in groups of beginning readers. Practice effects were minimal. There were strong relations between nationally normed measures of decoding and spelling and their experimental counterparts and with most measures of reading-related cognitive processes. The implications for the use of such tests in treatment studies that focus on beginning readers are discussed.     

The Effects of Timed and Untimed Testing Conditions on the Reading Comprehension Performance of Adults with Reading Disabilities

This study examined the effects of extra time on the reading comprehension performance of a heterogeneous group of adults with reading disabilities. Sixty-four adults participated. A clinic that assesses learning disabilities identified 22 as reading disabled, and 42 as normal readers. The 64 adults took a reading comprehension test under both timed and untimed conditions. Other skills measured included vocabulary, word reading, non-word reading, spelling, arithmetic, and short-term memory. Under timed conditions, there were significant differences between the participants with reading disabilities and the normally achieving participants. All of the reading disabled participants in the present study benefited from extra time, but the normally achieving readers performed similarly under the timed and untimed conditions. Further, in the untimed condition, the performance of the individuals with a less severe reading disability was not significantly different that of the Average readers. The study suggests that extra time during testing is an appropriate accommodation to help individuals begin to compensate for reading disabilities.     

Taiwanese families' perspectives on learning disabilities: an exploratory study in three middle schools

The purpose of this study was to investigate families' perspectives on learning disabilities (LD) in Taiwan. A researcher‐designed survey was sent out to families of children with or without LD from three middle schools. Data from 153 participants were gathered and analysed. The survey consisted of four sections, namely demographic information, children's reading performance, families' general understanding and perspectives of LD. Specifically, the last section of 54 Likert scale items designed to gather information about families' perspectives of LD was analysed with five domains: causes of LD (inherent or acquired), conceptions and misconceptions, attitudes (acceptance or rejection), disclosure of disabilities (willing or unwilling), and support. Results indicated that families were not familiar with educational services related to LD in schools. Additionally, families' experiences with people with disabilities resulted in different perspectives regarding the causes and conceptions about LD, and acquiring support. Families' perspectives on LD also correlated with personal characteristics, including the level of their children's reading performance, number of children and income level. The cultural implications of these findings interplay with an emphasis on academic performance are discussed.     

Word reading and word spelling in French adult literacy students: the relationship with oral language skills

We analysed word reading and spelling in French adults with low levels of literacy (A‐IL). As well as examining phonological and lexical processes, we explored the relationship between literacy and oral language skills. Fifty‐two adult literacy students were compared with reading level‐matched pupils in Years 1–3 of primary school on reading tasks (pseudoword reading, word reading, text comprehension), spelling tasks (pseudoword spelling, text dictation) and oral language tasks. A‐IL scored the same as children on word reading and spelling but less well on pseudoword reading and spelling. They also produced fewer phonologically acceptable errors in the dictation. Regarding oral language skills, as a group A‐IL encountered greater difficulty in phonology than in morphosyntax and semantics, and correlations revealed strong relationships between literacy levels and oral skills, particularly in the domain of phonology. Within their group, however, A‐IL displayed several distinct language profiles. These could reflect different risk factors leading to functional illiteracy and are discussed regarding the cognitive and environmental causes of impaired reading acquisition.     

Error Analysis of Mathematical Word Problem Solving Across Students with and without Learning Disabilities

Solving word problems is a common area of struggle for students with learning disabilities (LD). In order for instruction to be effective, we first need to have a clear understanding of the specific errors exhibited by students with LD during problem solving. Error analysis has proven to be an effective tool in other areas of math but has had little application to errors in word problems. Using an error analysis approach, this study aimed to investigate in depth the various types and frequency of errors made by students with LD and their AA peers during math problem solving. The resulting similarities and differences between the two groups of students are discussed with insight into underlying cognitive processes, and implications for future research.     

Cross-language transfer of phonological and orthographic processing skills from Spanish L1 to English L2

Previous cross-language research has focused on L1 phonological processing and its relation to L2 reading. Less extensive is the research on the effect that L1 orthographic processing skill has on L2 reading and spelling. This study was designed to investigate how reading and spelling acquisition in English (L2) is influenced by phonological and orthographic processing skills in Spanish (L1) in 89 Spanish-English bilingual children in grades 2 and 3. Comparable measures in English and Spanish tapping phonological and orthographic processing were administered to the bilingual children. We found that cross-language phonological and orthographic transfer occurs from Spanish to English. Specifically, the Spanish phoneme deletion task contributed a significant amount of unique variance to English word reading and spelling, for both real words and pseudowords. The Spanish homophone choice task predicted English reading, but not spelling. Taken together, these results suggest that there are shared phonological and orthographic processes in bilingual reading; however, orthographic patterns may be language specific, thereby not likely to transfer to spelling performance.     

Students with reading and spelling disabilities: peer groups and educational attainment in secondary education

The present study investigated whether the members of adolescents' peer groups are similar in reading and spelling disabilities and whether this similarity contributes to subsequent school achievement and educational attainment. The sample consisted of 375 Finnish adolescents whose reading and spelling disabilities were assessed at age 16 with the Finnish dyslexia screening test. The students also completed a sociometric nomination measure that was used to identify their peer groups. Register information on participants' school grades also was available, and educational attainment in secondary education was recorded 5 years after completion of the 9 years of basic education. The results revealed that the members of adolescent peer groups resembled each other in reading disabilities but not in those of spelling. Reading disabilities and academic achievement shared within the peer group also contributed to educational attainment in secondary education. Finally, reading disabilities played a larger role in educational attainment among males than among females.     

Speaking to read: The effects of speech recognition technology on the reading and spelling performance of children with learning disabilities

In recent literature on persons with learning disabilities (LD), speech recognition has been discussed primarily as an assistive technology to help compensate for writing difficulties. However, prior research by the authors has suggested that in addition to helping persons to compensate for poor writing skills, speech recognition also may enhance reading and spelling; that is, what was designed as assistive technology appears to serve remedial functions as well. The present study was conducted to determine whether elementary and secondary students with LD who used the technology to write self-selected compositions and class assignments would demonstrate improvements in reading and spelling. Thirty-nine students with LD (ages 9 to 18) participated. Nineteen participants used speech recognition 50 minutes a week for sixteen weeks, and twenty students in a control group received general computer instruction. Results indicated that the speech recognition group showed significantly more improvement than the control group in word recognition (p<.0001), spelling (p<.002) and reading comprehension (p<.01). Pre- and posttests on five reading-related cognitive processing measures (phonological, orthographic, semantic processing, metacognitive reading strategies, and working memory) indicated that for the experimental group, only phonological processing improved significantly over the treatment period when compared to controls (p<.04). Further ANCOVA suggested that growth in phonological processing was associated with significant differences among conditions for all three academic measures: word recognition, spelling, and reading comprehension.

The effects of age and sublexical automaticity on reading outcomes for students with reading disabilities

For students with reading disabilities, reading fluency has proven difficult to remediate. The current study examined age‐related effects on measures of word and text‐reading outcomes, within the context of a phonologically based remedial reading program. The contribution of speeded‐reading of sublexical sound–spelling patterns to fluency outcomes was also examined. The youngest group of participants showed better outcomes on measures of word and pseudoword reading. All age groups made significant and meaningful improvements on measures of reading fluency and reading comprehension. Participants' mastery of speeded, sublexical sound–spelling reading contributed variance to fluency outcomes beyond pre‐intervention fluency scores. Practice with sublexical spelling patterns may be one important component of programs directed at remediating accuracy and fluency deficits for students with reading disabilities. What is already known about this topic

• Reading fluency has proven difficult to remediate for students with reading disabilities.
• Training with sublexical sound–spelling patterns has increased recognition of the trained patterns, but transfer has been limited.
• Young children with reading difficulties appear to have an advantage at closing the reading achievement gap; however, there are some inconsistencies in the literature.

What this paper adds

• Automaticity with sublexical patterns made a unique contribution to fluency outcomes in this sample of students with reading disabilities.
• In the context of the reading program examined, all age groups made significant and meaningful standard score gains on reading fluency.
• Young children did not score higher than the two older groups on measures of oral reading fluency or reading comprehension; bringing into question conclusions drawn from prevention versus intervention studies.

Implications for theory and practice

• Findings lend support to models of reading acquisition that emphasize multilayered, sublexical spelling–sound knowledge as important to reading fluency, beyond that of sight‐word reading efficiency.
• Including speeded practice of a broad range of sublexical sound–spelling patterns and training these to mastery deserves further study as one potential approach to improving fluency interventions for students with reading disabilities.
• We suggest that this sublexical training may mimic reading practice in terms of building orthographic representations that support fluent reading.

     

Teaching English Language Learners At Risk for Reading Disabilities to Read: Putting Research into Practice

The purpose of this article is to describe features of interventions that are empirically validated for use with first‐grade students at risk for reading disabilities who are English language learners (ELLs) and whose home language is Spanish. The empirical evidence supporting these interventions is summarized. Interventions for improving oral language and reading abilities with struggling readers who are ELLs taught in either Spanish or English are described as a means to assist school districts and teachers in defining and implementing effective interventions for ELLs at risk for reading difficulties. The interventions described may be useful to educators seeking information about Response to Intervention as a means of identifying ELLs who require services for learning disabilities.
