Identifying students with dyslexia in higher education

An increasing number of students with dyslexia enter higher education. As a result, there is a growing need for standardized diagnosis. Previous research has suggested that a small number of tests may suffice to reliably assess students with dyslexia, but these studies were based on post hoc discriminant analysis, which tends to overestimate the percentage of systematic variance, and were limited to the English language (and the Anglo-Saxon education system). Therefore, we repeated the research in a non-English language (Dutch) and we selected variables on the basis of a prediction analysis. The results of our study confirm that it is not necessary to administer a wide range of tests to diagnose dyslexia in (young) adults. Three tests sufficed: word reading, word spelling and phonological awareness, in line with the proposal that higher education students with dyslexia continue to have specific problems with reading and writing. We also show that a traditional postdiction analysis selects more variables of importance than the prediction analysis. However, these extra variables explain study-specific variance and do not result in more predictive power of the model.     

Questioning the benefits that coloured overlays can have for reading in students with and without dyslexia

Visual stress (the experience of visual distortions and discomfort during prolonged reading) is frequently identified and alleviated with coloured overlays or lenses. Previous studies have associated visual stress with dyslexia and as a consequence, coloured overlays are widely distributed to children and adults with reading difficulty. However, this practice remains controversial. We investigated whether overlays have advantageous and reliable benefits for reading in undergraduate students with and without dyslexia. Both groups read jumbled text faster with a coloured overlay than without. The dyslexic group did not show greater gains than controls, despite reporting significantly more symptoms of visual stress. However, coloured overlays did not improve reading rate or comprehension of connected text. The improvement in reading speed with an overlay was not reliable and was significantly reduced at retesting for dyslexic students. These results question the value of coloured overlays as a tool for identifying visual stress and as a form of remediation for the reading difficulties associated with 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.     

Is sensitivity to rhyme a developmental precursor to sensitivity to phoneme?: Evidence from individuals with Down syndrome

This study investigated sensitivity to rhymeand phoneme among readers and nonreaders with Down syndrome (DS) and normally developingchildren. Three tasks were administered toevaluate sensitivity to rhyme and phoneme: arhyme detection task, an initial phonemedetection task, and a middle phoneme detectiontask. Results for the normally developingchildren replicated the results of previousstudies suggesting that the ability to detectrhyme is a developmental precursor of theability to detect phonemes. Although all taskswere very easy for the children who had alreadystarted to read, the nonreaders found the rhymedetection task significantly easier than eitherthe initial or the middle phoneme detectiontask. On the other hand, there was scarcelyany indication that the individuals with DSfound the rhyme detection task easier thaneither one of the phoneme detection tasks.While all tasks were very difficult for thenonreaders with DS, the DS individuals who hadalready started to read found the rhymedetection task significantly more difficultthan both the initial and the middle phonemedetection tasks.     

Investigating self-regulated study strategies among postsecondary students with and without dyslexia: a diary method study

We investigated the use of self-regulated study strategies among undergraduates with dyslexia by means of extensive web-based diary data, comparing their strategy use to that of matched students without dyslexia who completed the diary in the same period. Additionally, we examined the perceived benefits of using the recorded strategies in both groups, as well as relationships between the recorded strategies and perceived self-efficacy and academic performance. Results indicated that across lecture, individual study, and social study contexts, students with and without dyslexia recorded a comparable, broad range of strategies, yet students with dyslexia seemed to use particular visual and social strategies more consistently than did students without dyslexia. Across the three study contexts, both students with and without dyslexia also perceived the strategies they recorded in the diaries to be quite beneficial, but with particular visual and social strategies seemingly perceived as more helpful by students with dyslexia. Finally, self-regulated study strategies were positively related to perceived self-efficacy and academic performance among the students with dyslexia but not among the students without dyslexia. We discuss the possibility that the diary method used to assess strategy use among students with dyslexia in different study contexts over time was more appropriate for revealing the breadth and value of their strategy repertoire than the decontextualized, one-time questionnaire and interview approaches used in prior work.     

Using computer-based readers to improve reading comprehension of students with dyslexia

Twenty-eight middle school students, diagnosed as dyslexic and attending a school using the Slingerland approach to remediation of dyslexia, used a computer-based reading system for reading literature for about one-half hour a day for a semester. The system proved to be a strong compensatory aid, enabling 70 percent of the students to read with greater comprehension, approximately one grade level or more improvement, as measured by the Gray Oral Reading Test. For 40 percent of the students, the gains were large, from two to as much as five grade levels. However, not all students benefited. Fourteen percent showed lower comprehension scores when using the system, and there is some indication that this degradation is associated with kinesthetic-motor weakness. Some students reported gains in reading speed and exhibited increased span of attention for and endurance in reading when using the system. We did not find evidence that the computer-reader technology provided a positive remediation benefit incremental to that obtained from the school’s intensive Slingerland remediation program. Our results indicate that computer-readers are important compensatory aids that can enable many people with dyslexia to perform more effectively in reading-related tasks associated with school and work.     

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.

Learning strategies and study approaches of postsecondary students with dyslexia

The present study describes the self-reported learning strategies and study approaches of college and university students with and without dyslexia and examines the relationship of those characteristics with reading ability. Students with (n = 36) and without (n = 66) dyslexia completed tests measuring reading rate, reading comprehension, reading history, learning strategies, and learning approaches. The results indicated that students without dyslexia obtained significantly higher scores than students with dyslexia in their reported use of selecting main ideas and test taking strategies. Students with dyslexia reported significantly greater use of study aids and time management strategies in comparison to students without dyslexia. Moreover, university students with dyslexia were significantly more likely to report a deep approach to learning in comparison to university students without dyslexia. Reading ability correlated positively with selecting main ideas and test taking strategies and negatively with use of study aids. The authors interpret the learning strategy results as consequences of and compensations for the difficulties that students with dyslexia have in word reading.     

The representation and attainment of students with dyslexia in UK higher education

Using a database of allstudents in higher education in the UK in1995–1996, students with dyslexia and those withno reported disability were compared in termsof demographic properties, programmes of studyand academic attainment. Students with dyslexiaconstituted 0.42% of all students resident inthe UK. Their representation varied with age,gender, ethnicity and entrance qualificationsand with their level, mode and subject ofstudy. Students with dyslexia were more likelyto withdraw during their first year of studyand were less likely to complete theirprogrammes of study, although with appropriatesupport the completion rate of students withdyslexia can match that of students with nodisabilities. In addition, students withdyslexia who completed first-degree programmestended to gain a poorer class of honours thanstudents with no reported disability, but 40%obtained first-class or upper second-classhonours. In short, dyslexia may havedeleterious consequences for progression,completion and achievement in higher education,but it is by no means incompatible with a highlevel of success, given appropriate commitmenton the part of the students and appropriateresources on the part of their institution.     

Tier 3 specialized writing instruction for students with dyslexia

Two instructional experiments used randomized, controlled designs to evaluate the effectiveness of writing instruction for students with carefully diagnosed dyslexia, which is both an oral reading and writing disorder, characterized by impaired word decoding, reading, and spelling. In Study 1 (4th to 6th grade sample and 7th to 9th grade sample), students were randomly assigned to orthographic or morphological spelling treatment but all students were taught strategies for planning, writing, and reviewing/revising narrative and expository texts. Both treatments resulted in improvement on three measures of spelling and one measure of composition. Morphological treatment resulted in better improvement in spelling pseudowords, whereas orthographic treatment resulted in better improvement in rate of reading pseudowords. In Study 2 (4th to 6th grade sample), students were randomly assigned to explicit language treatment (phonological working memory + phonological-orthographic spelling + science report writing training) or nonverbal problem solving treatment (virtual reality-based computer simulation, drawing maps, and building clay models). Both treatments used science content material and resulted in significant improvement in spelling and reading pseudowords (accuracy and rate). The surprising finding was that hands-on, engaging science problem solving led to more improvement in phonological working memory than did specialized phonological instruction. Only when spelling instruction emphasized orthography or morphology (Study 1) did real word spelling improve. Preparation of this chapter was supported by Grant Nos. HD25858 and P50 33812 from the National Institute of Child Health and Human Development (NICHD). In Study 1 teaching assistants included Sylvia Abbott, Marci Anderson-Youngstrom, Belle Chennault, Kate Eschen, Noelia Garcia, Sandra Hiramatsu, Lynn Junell, Julia Kim, Stephanie King, Shin-Ju (Cindy) Lin, Rebecca Metzger, Heather Murphy, Jennifer Norton, Sue Palewicz, Rebecca Pirie, and Suzanna West. Also on the assessment team were Sylvia Abbott, Belle Chenault, Kate Eschen, and Rebecca Pirie. Certified teachers Diana Hoffer and Christina Johnson implemented the composition lessons written by the first author. In Study 2, teaching assistants included Nicole Alston-Abel, Leah Altemeier, Wade Altom, Marci Anderson-Youngstrom, Annie Boyd, Nicole Garcia, Laura Gould, Marta Holsinger, Yen-Ling Lee, Shin-Ju (Cindy) Lin, Laurie McCarthy, Heather Murphy, Hema O’Shea, Michelle Proux, Kristine Tardiff, and Kari Terjeson. Janine Jones supervised the assessment team. Margaret McShane and Doug Stock served as administrative assistants.     

Development of lexical tone awareness in Chinese children with and without dyslexia

This paper describes two studies that examined the lexical tone awareness of Chinese children both with and without dyslexia at different primary school ages.Study 1 examined the contributions of lexical tone awareness to distinguish children with and without dyslexia with respect to their Chinese character reading skills. Two hundred and seventy Chinese children participated in Study 1. Ninety of these were children with dyslexia (equally recruited from second, fourth, and sixth grades). Moreover, ninety children functioned as a chronological-age control group, and an additional ninety children functioned as a reading-level control group. The participants were tested for nonverbal intelligence, Chinese character reading, and cognitive-linguistic skills and lexical tone awareness. Our results revealed a later developmental ceiling in Chinese children with dyslexia than in those without dyslexia. Furthermore, children’s lexical tone awareness could serve to distinguish children with dyslexia from typically developing children in all primary school years.Study 2 compared the lexical tone awareness and Chinese character reading skills of Chinese children with dyslexia both before and after introducing the Perceptual Training Method. The participants in this study consisted of all the participants with dyslexia from Study 1, and the measurements were the Chinese character reading test and the lexical tone awareness task from Study 1. Our results revealed that only second-grade children with dyslexia gained substantially from the training on both lexical tone awareness and character naming, whereas those in the fourth grade obtained a significant improvement only on lexical tone awareness.     

Spelling consistency affects reading in young Dutch readers with and without dyslexia

Lexical-decision studies with experienced English and French readers have shown that visual-word identification is not only affected by pronunciation inconsistency of a word (i.e., multiple ways to pronounce a spelling body), but also by spelling inconsistency (i.e., multiple ways to spell a pronunciation rime). The aim of this study was to compare the reading behavior of young Dutch readers with dyslexia to the behavior of readers without dyslexia. All students participated in a lexical-decision task in which we presented pronunciation-consistent words and pseudowords. Half of the pronunciation-consistent stimuli were spelling consistent and the other half were spelling inconsistent. All three reader groups, that is, students with dyslexia, age-match students, and reading-match students, read spelling-consistent words faster than spelling-inconsistent words. Overall reading speed of students with dyslexia was similar to that of reading-match students, and was substantially slower than that of age-match students. The results suggest that reading in students with or without dyslexia is similarly affected by spelling inconsistency. Subtle qualitative differences emerged, however, with respect to pseudoword identification. The conclusion was that the findings were best interpreted in terms of a recurrent-feedback model.     

Artificial grammar learning in primary school children with and without developmental dyslexia

This paper explores implicit learning in typically developing and primary school children (9–12 years old) with developmental dyslexia using an artificial grammar learning (AGL) task. Two experiments were conducted, which differed in time of presentation and nature of the instructional set (experiment 1—implicit instructions vs experiment 2—explicit instructions). Repeated measures analysis of variance (group × grammaticality × chunk strength) showed a group effect only in experiment 1 (implicit instructions), with only the typically developing children showing evidence of AGL. There was a grammaticality effect (adherence to the rules) for both groups in the two experimental situations. We suggest that the typically developing children exhibited intact implicit learning as manifested in AGL performance, whereas children with developmental dyslexia failed to provide such evidence due to possible mediating cognitive developmental factors.     

Foreign language reading and spelling in gifted students with dyslexia in secondary education

A few studies suggest that gifted children with dyslexia have better literacy skills than averagely intelligent children with dyslexia. This finding aligns with the hypothesis that giftedness-related factors provide compensation for poor reading. The present study investigated whether, as in the native language (NL), the level of foreign language (FL) literacy of gifted students with dyslexia is higher than the literacy level of averagely intelligent students with dyslexia and whether this difference can be accounted for by the difference in their NL literacy level. The sample consisted of 148 Dutch native speaking secondary school students divided in four groups: dyslexia, gifted/dyslexia, typically developing (TD), and gifted. All students were assessed on word reading and orthographic knowledge in Dutch and English when they were in 7th or 8th grade. A subsample (n = 71) was (re)assessed on Dutch, English, French, and German literacy one year later. Results showed that Dutch gifted students with dyslexia have higher NL literacy levels than averagely intelligent students with dyslexia. As in the NL, a stepwise pattern of group differences was found for English word reading and spelling, i.e., dyslexia < gifted/dyslexia < TD < gifted. However, it was not found for French and German literacy performance. These results point towards compensation: the higher English literacy levels of gifted/dyslexic students compared to their averagely intelligent dyslexic peers result from mechanisms that are unique to English as a FL. Differences in results between FLs are discussed in terms of variation in orthographic transparency and exposure.     

Visual and language processing deficits in compensated and uncompensated college students with dyslexia

In seven experiments, we investigated whether compensated and uncompensated adults with dyslexia show different patterns of deficits in magnocellular visual processing and in language processing tasks. In four visual tasks, we failed to find evidence of magnocellular deficits in either group. However, both groups of adults with dyslexia showed deficits in component language skills, and the degree of reading impairment predicted the nature and extent of these deficits. Uncompensated readers showed deficits in orthographic and especially phonological coding and awareness and were slower on rapid naming. Compensated readers showed word and nonword performance below controls but better than the uncompensated readers. The compensated group was not significantly less accurate than controls on phonological awareness, nor significantly worse overall on rapid naming.     

University transition experiences of four students with dyslexia in New Zealand

This study considered the previous educational experiences, decision-making, and first-year experiences of four students who self-identified as learning with dyslexia within one university in New Zealand. The study showed that despite achieving the required standards for entrance to study at university, some students lacked the knowledge and self-advocacy skills necessary to access the learning support available to them at the university. Without good quality, relevant and focused course advice, students with dyslexia are at risk of being mismatched in academic programs, failing to complete their courses of study and incurring financial costs. With appropriate course advice, connecting to support services early, and applying proven study and time management strategies, these students are able to achieve grades higher than in compulsory education, suggesting that high school academic results should not be used as a predictor of their success at university. By understanding the learning experiences of successful students with dyslexia as they transition to university, we can improve how we encourage and support academically capable students who struggle with literacy in their compulsory and tertiary education.     

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.
