Cognitive skills and literacy performance of Chinese adolescents with and without dyslexia

The present study sought to identify cognitive abilities that might distinguish Hong Kong Chinese adolescents with dyslexia and to assess how these abilities were associated with Chinese word reading, word dictation, and reading comprehension. The cognitive skills of interest were morphological awareness, visual-orthographic knowledge, rapid naming, and verbal working memory. A total of 90 junior secondary school students, 30 dyslexic, 30 chronological age controls, and 30 reading level controls was tested on a range of cognitive and literacy tasks. Dyslexic students were less competent than the control students in all cognitive and literacy measures. The regression analyses also showed that verbal working memory, rapid naming, morphological awareness, and visual-orthographic knowledge were significantly associated with literacy performance. Findings underscore the importance of these cognitive skills for Chinese literacy acquisition. Overall, this study highlights the persistent difficulties of Chinese dyslexic adolescents who seem to have multiple causes for reading and spelling difficulties.     

Language development and literacy skills in late-talking toddlers with and without familial risk for dyslexia

The relationship between late-talkers' language development and reading and spelling outcomes was examined in children with and without familial risk for dyslexia. The late-talking subgroups were defined using parent- and test-based assessments of receptive and expressive vocabulary and grammar at 2 and 2.5 years as intake criteria. The language skills of late talkers and the remainders of these two groups were assessed at 3.5, 5, and 5.5 years. Reading/spelling outcomes were compared at the end of the second grade. Late-talking toddlers of the at-risk group who had both poor receptive and expressive skills performed less well than all other groups on language measurements at 5.5 years. In contrast, the control group's late talkers with an expressive delay reached the language level of their age-mates already by 3.5 years, and maintained their age-appropriate position two years later. The most significant differences in the reading skills were found between the at-risk children with receptive and expressive delay and the remainder of the controls. Age-appropriate early language skills did not, however, ensure norm-level fluent reading in the at-risk group. The remainder of the at-risk group performed at a significantly lower level than did the remainder of the controls, both on the oral reading and spelling tasks.     

Coexisting problem behaviour in severe dyslexia

A small group of children and young adolescent with dyslexia has severely impaired reading skills despite prolonged special education. These are the students in focus. In dyslexia, problem behaviour, internalised as well as externalised, has previously been reported, so also for the participants with dyslexia in this study. The aim of the present study was to obtain more in‐depth knowledge of the behaviour problems from various informants, representing different settings. This kind of information is imperative for identifying problem behaviour, and for planning and implementing remedial programmes. A clinical group of 70 students with severe dyslexia, due to phonological problems, and a control group of 70 without reading problems participated. The two groups were pair‐wise matched on age, gender, cognitive level and whether they lived in rural or urban areas. Mean age was 150 months, and mean IQ was approximately 100 in both groups. Parents, teachers and participants provided information on behaviour through the Achenbach questionnaires Child Behavior Checklist, Teacher's Report Form and Youth Self Report. Behaviour is, in these questionnaires, divided into eight syndrome areas called Withdrawn, Somatic Complaints, Anxious/Depressed, Social Problems, Thought Problems, Attention Problems, Delinquent Behavior and Aggressive Behavior. The three informant groups reported significantly more problems in the dyslexia group than in the controls in all the syndrome areas. Parents reported more children with dyslexia to be anxious and depressed, and have social problems and attention problems than teachers. They also reported suicidal ideations in nine participants with dyslexia. In addition, parents rated more internalising and total problems in the dyslexia group than teachers.     

Developmental dyslexia: Heterogeneity without discrete subgroups

Is the dual route model of word recognition useful in explaining individual differences in reading behaviors for most developmental dyslexics? Many past case studies of surface and phonological acquired dyslexics and a few similar studies of developmental dyslexia have suggested this might be so. The present study investigated individual differences among a group of 65 dyslexics, age 10 to 13, in reading, phonemic segmentation, and word retrieval. The dyslexics’ performance was compared to that of 65 reading age controls and 17 age-matched good readers. The research questions were: (1) Are there discrete subgroups of developmental dyslexics as suggested by the case studies? (2) How do oral language measures relate to the various reading tasks? The data indicated there were no discrete subgroups within the group of dyslexics; in addition, the variability in performance on reading tasks was quite similar for the dyslexic and reading age-control groups. A few dyslexics resembled phonological dyslexics and surface dyslexics, but these subjects were still part of a continuum. We also report the relationship between phonemic segmentation and word retrieval and various reading tasks. It appears that dyslexics at extreme ends of the continuum may exhibit quite different patterns from each other in their oral language task performance as well as in their reading.

Conceptualisations of literacy and literacy practices for children with severe learning difficulties

Literacy is traditionally narrowly conceptualised as a set of skills related to accessing and generating written or printed text. For children designated as having severe learning difficulties (SLD), who are unlikely to develop these ‘conventional’ literacy skills, such a conception implies their semi‐literacy or nonliteracy. Although conceptions of multimodal literacy and multiliteracies have rarely been applied to this group, broader understandings of literacy that include a range of activities, modes and media provide greater opportunities for including these learners in literacy practices. Drawing upon our research with teachers of this group of children and young people, we illustrate these literacy practices. We note, however, that such practices are often haphazard, not coherently thought through, and that there is much confusion regarding any distinction between communication and literacy. We argue for literacy as a specific form of communication, but conclude that broader models of literacies should be utilised to guide and support practitioners in developing interactive practice and in making reasoned and principled approaches and decisions about literacy practices, routes and progression for children with SLD.     

Copying skills in children with and without dyslexia

Visual stress in adults with and without dyslexia

The relationship between dyslexia and visual stress (sometimes known as Meares‐Irlen syndrome) is uncertain. While some theorists have hypothesised an aetiological link between the two conditions, mediated by the magnocellular visual system, at the present time the predominant theories of dyslexia and visual stress see them as distinct, unrelated conditions, a view that has received some support from studies with children. Studies of visual stress in adults are rare, yet recent reports of a high incidence of this phenomenon amongst university students with diagnosed dyslexia call for further investigation of the issue. This study sought to clarify the relationship between visual stress and dyslexia by comparing the reading performance of dyslexic and non‐dyslexic adults with, and without, colour. Degree of susceptibility to visual stress was determined by means of a symptom rating scale. Optimal colour was determined using an Intuitive Colorimeter, which was also employed to assess reading speed under the two experimental conditions. Only the dyslexic students with high visual stress showed significant gains in reading speed when using optimal colour. The use of response to treatment (rather than symptomatology) as a diagnostic criterion for visual stress is questioned, especially when applied to adults, as this may give misleading findings. On the basis of reported symptomatology, students who experience high levels of visual stress are more likely to show improvements in reading rate with optimal colour if they also have dyslexia than if they do not have dyslexia. Although not establishing an aetiological link, these findings imply an interaction between the two conditions with major implications for theory, diagnosis and treatment.     

Reviewing evidence‐based practice for pupils with dyslexia and literacy difficulties

There is now a strong evidence base from theory and research providing a ‘template’ to inform practice at Wave 2, guiding the design and implementation of time‐limited effective early intervention programmes for pupils identified as ‘at risk’ of reading difficulties following initial literacy instruction (Rose, 2009). In contrast, there is currently an absence of evidence to guide the more fine‐grained selection and design of specific interventions (Wave 3) for those nonresponders to otherwise effective reading intervention. In this paper, we first outline our current understanding of the characteristics of effective early intervention programmes, and of the pupils who do not respond. Three theoretically motivated single‐case studies from developmental theory and processing models of skilled performance are then considered as a source of evidence providing useful insights into the type of assessment needed to inform the planning of highly individualised intervention programmes for pupils with severe and persisting literacy difficulties.     

Secondary symptoms of dyslexia: a comparison of self-esteem and anxiety profiles of children with and without dyslexia

The secondary symptoms of individuals with dyslexia, such as high anxiety and low self-esteem, have aroused various debates not only in the educational, but also in the clinical context. Since pro and contra arguments are supported by a more or less equal number of empirical findings, no final conclusion could be drawn for this specific phenomenon. The current study aims to contribute more data in this respect and offers a possible explanation for both sides that either support or reject the relationship between dyslexia and its secondary symptoms. The main investigation of this study is the comparison of anxiety and self-esteem profiles of children with and without dyslexia. Participants are 124 school children aged between eight and 11 years. Their IQ as well as their reading and writing ability were also measured and used as control variables. All data were collected and analysed using a quantitative approach. Effect sizes are also provided in order to facilitate meta-analysis in the future and to confirm the results of a significant test. The results indicate that children with dyslexia have anxiety and self-esteem issues in the specific context or domain. However, their general anxiety and self-esteem were not impaired. A discussion regarding the possibility and/or the necessity of the secondary symptoms of dyslexia is also provided.     

Computer-based learning of spelling skills in children with and without dyslexia

Our spelling training software recodes words into multisensory representations comprising visual and auditory codes. These codes represent information about letters and syllables of a word. An enhanced version, developed for this study, contains an additional phonological code and an improved word selection controller relying on a phoneme-based student model. We investigated the spelling behavior of children by means of learning curves based on log-file data of the previous and the enhanced software version. First, we compared the learning progress of children with dyslexia working either with the previous software (n = 28) or the adapted version (n = 37). Second, we investigated the spelling behavior of children with dyslexia (n = 37) and matched children without dyslexia (n = 25). To gain deeper insight into which factors are relevant for acquiring spelling skills, we analyzed the influence of cognitive abilities, such as attention functions and verbal memory skills, on the learning behavior. All investigations of the learning process are based on learning curve analyses of the collected log-file data. The results evidenced that those children with dyslexia benefit significantly from the additional phonological cue and the corresponding phoneme-based student model. Actually, children with dyslexia improve their spelling skills to the same extent as children without dyslexia and were able to memorize phoneme to grapheme correspondence when given the correct support and adequate training. In addition, children with low attention functions benefit from the structured learning environment. Generally, our data showed that memory sources are supportive cognitive functions for acquiring spelling skills and for using the information cues of a multi-modal learning environment.     

What is literacy for students with severe learning difficulties? Exploring conventional and inclusive literacy

This paper arises from research into inclusive literacy for pupils with severe learning difficulties who do not learn to read and write conventionally. The ultimate aim of the study was to seek out examples of good practice in teaching and learning literacy that includes students with severe learning difficulties and disseminate them as widely as possible. Thirty-five schools were visited and observations made in 122 lessons. Sixty-one teachers were interviewed and their paperwork examined. Ten focus groups and five 'expert witnesses' were consulted, alongside desk-based research designed to locate 'good practice'. Teachers used a mixture of conventional (e.g., texts) and non-conventional (e.g., pictures, film and oral) media, although more observations were made of conventional literacy teaching (e.g., phonic work) than of non-conventional (e.g., filmmaking). Results from the research suggest that few students with severe learning difficulties are likely to learn to read and write conventionally (i.e., read for pleasure, work and study) and teachers may be relying too much on teaching traditional literacy to them. It may be useful to explore teaching and learning around alternative media such as still and moving images, live theatre and storytelling, digital technology and the arts. Although some teachers are making good use of these media, the potential of these media for providing inclusive literacy experiences could be further developed.
