Dyslexie font does not benefit reading in children with or without dyslexia

In two experiments, the claim was tested that the font “Dyslexie”, specifically designed for people with dyslexia, eases reading performance of children with (and without) dyslexia. Three questions were investigated. (1) Does the Dyslexie font lead to faster and/or more accurate reading? (2) Do children have a preference for the Dyslexie font? And, (3) is font preference related to reading performance? In Experiment 1, children with dyslexia (n?=?170) did not read text written in Dyslexie font faster or more accurately than in Arial font. The majority preferred reading in Arial and preference was not related to reading performance. In Experiment 2, children with (n?=?102) and without dyslexia (n?=?45) read word lists in three different font types (Dyslexie, Arial, Times New Roman). Words written in Dyslexie font were not read faster or more accurately. Moreover, participants showed a preference for the fonts Arial and Times New Roman rather than Dyslexie, and again, preference was not related to reading performance. These experiments clearly justify the conclusion that the Dyslexie font neither benefits nor impedes the reading process of children with and without dyslexia.     

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.     

The effect of the method of repeated readings on the reading rate and word recognition accuracy of deaf adolescents

This study examined the effects of the method of repeated readings (RR), a well-accepted remedial reading technique for improving the reading rate of hearing children, with deaf adolescents. Forty-two students from a midwestern residential school for the deaf were randomly assigned into treatment and control groups. The groups were equivalent with respect to age, level of hearing loss, reading achievement, and mental ability. All subjects read material previously determined to be at their instructional levels. Members of the treatment group were videotaped during the initial reading of an assigned passage, allowed to practice over three 15-minute sessions, then videotaped again during a final reading of the assigned passage. The control group differed only in that it practiced reading material other than the assigned passage. Reading rates and word recognition accuracy were recorded for the initial and final reading of each of five passages. Results indicated that the treatment subjects demonstrated significant improvement between pre- and posttesting regarding reading rate and two measures of word recognition accuracy. The performance of subjects engaged in nonrepetitive reading demonstrated minimal improvement. We discuss applicability of this procedure with a deaf population and implications for future research and practice.     

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.     

An interaction-dominant perspective on reading fluency and dyslexia

The background noise of response times is often overlooked in scientific inquiries of cognitive performances. However, it is becoming widely acknowledged in psychology, medicine, physiology, physics, and beyond that temporal patterns of variability constitute a rich source of information. Here, we introduce two complexity measures (1/f scaling and recurrence quantification analysis) that employ background noise as metrics of reading fluency. These measures gauge the extent of interdependence across, rather than within, cognitive components. In this study, we investigated dyslexic and non-dyslexic word-naming performance in beginning readers and observed that these complexity metrics differentiate reliably between dyslexic and average response times and correlate strongly with the severity of the reading impairment. The direction of change in the introduced metrics suggests that developmental dyslexia resides from dynamical instabilities in the coordination among the many components necessary to read, which could explain why dyslexic readers score below average on so many distinct tasks and modalities.     

Phonology,reading development,and dyslexia: A cross-linguistic perspective

In this paper, I present a theoretical overview at the cognitive level of the role of phonological awareness in reading development and developmental dyslexia across languages. My assumption is that the primary deficit in developmental dyslexia in all languages lies in representing speech sounds: a deficit in “phonological representation.” I will argue that this deficit manifests in somewhat different ways, depending on orthography. I will also argue that the phonological deficit in dyslexia is initially at the syllable and onset-rime levels of phonological awareness, with the development of “phonemic” awareness being a consequence rather than a precursor of reading. Finally, I will suggest that some of the processes underpinning language acquisition are disrupted in dyslexia, in particular, the detection of rhythm in speech.     

Lessons from the reading brain for reading development and dyslexia*

The purpose of this study was to examine Australian learning difficulties specialists’ knowledge about, and the use of, the term dyslexia. An online survey was constructed based on a current definition of, and evidence about, dyslexia and distributed to members of relevant professional associations. A total of 179 participants responded to the survey. Statistical tests were used to identify significant differences in questionnaire scores between a number of demographic subgroups which included special professional interest group, professional discipline, years of experience and engagement in reading-related university study. Results indicated that these Australian professionals all possess a similar and generally high level of accurate research-based knowledge about dyslexia and how to support individuals with significant reading issues. However, while affirming the relevancy of the term dyslexia in their professional work, most participants preferred another term and favoured a combination of words including reading, learning and the less pejorative term difficulty as opposed to disability. As the term dyslexia is commonly used by Australian educators, policy-makers, support organisation and parents to make decisions about the support individuals receive, an understanding of what is currently understood by this label is critical.     

The development of reading speed in Italians with dyslexia: a longitudinal study

The development of reading speed in Italian children with dyslexia was estimated using individualized growth curves for a group of 38 children with dyslexia tested longitudinally from the second to the eighth grade and compared with typical readers. Their reading speed development followed a linear trend of .3 syllables per second per grade, approximately half the increment observed in typical children reading a passage and similar to typical children's reading of nonword lists. These findings give support to the deficit hypothesis versus the lag hypothesis and to reading speed as the core deficit in dyslexia with transparent orthographies.     

The impact of a collaborative family/school reading programme on student reading rate

Student reading skills are below grade level in many schools and professionals are constantly searching for new ideas to enhance reading curricula. To address this problem in one elementary school, a parent/school reading programme was implemented. Parents were encouraged to increase the amount of time spent reading with their children at home and the school provided easily accessible reading materials, suggestions for encouraging reading at home, prizes and special activities. Programme participants demonstrated a higher increase in reading rate and accuracy than the matched peers. Prior to implementation and at the end of the reading programme, parents and students who chose to participate in the programme reported positive attitudes toward reading together. Implications of these results are discussed and an emphasis is placed on expanding research in the area.     

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.     

It matters whether reading comprehension is conceptualised as rate or accuracy

This study shows that it makes a difference whether accuracy measures or rate measures are used when assessing reading comprehension. When the outcome is reading comprehension accuracy (i.e., the number of correct responses), word reading skills (measured as access to orthographic representations) account for a modest amount of the variance in the reading comprehension of 10‐year old children. However, this changes when reading comprehension is conceptualised as rate (i.e., number of correct responses per minute); when this is done, the correlation with word reading increases. The result was validated in two different reading comprehension tests. Moreover, this study indicates that it is not merely efficient word reading that influences the process of comprehending at a fast rate. When word reading and receptive vocabulary are controlled, a written measure of the ability to access and connect similar word meanings (synonym judgement) explains additional variance in reading comprehension rate.     

When diglossia meets dyslexia: The effect of diglossia on voweled and unvoweled word reading among native Arabic-speaking dyslexic children

Native Arabic speakers read in a language variety that is different from the one they use for everyday speech. The aim of the present study was: (1) to examine Spoken Arabic (SpA) and Standard Arabic (StA) voweled and unvoweled word reading among native-speaking sixth graders with developmental dyslexia; and (2) to determine whether SpA reading ability among children with dyslexia predicts StA reading fluency in the two orthographies: voweled and unvoweled. A comparison was made to three age groups of typically developing children: a group matched by chronological age, a group of children who are two years younger, and a group of children who are 4 years younger. Findings show that diglossia has a strong impact on reading ability in dyslexic children. Moreover, vowelization plays a pivotal role in the reading ability of Arabic-speaking children with dyslexia in both SpA and StA. This role is evident in the different performance patterns of dyslexic participants as compared with controls on word-reading accuracy and fluency for SpA versus StA. Finally, StA word-reading fluency appears to depend on and to be reliably and powerfully predicted by SpA word-level reading ability. These results underscore the role of diglossia and vowelization in the manifestation of dyslexia in Arabic-speaking children.     

Language abilities, reading acquisition, and developmental dyslexia: a discussion of hypothetical and observed relationships.

Tests of a model of the expected relationships between language abilities and reading achievement measures from the beginning of kindergarten through third grade are discussed. At kindergarten, more global language abilities influenced early, wholistic measures of reading achievement, including letter and number naming. At Grade 1, these earlier accomplishments had a direct effect on word recognition, but a second direct effect was also apparent for word and pheneme segmentation measured in kindergarten. Comprehension at Grade 1 was influenced primarily by word recognition abilities at the same time. At Grade 2, comprehension influenced word recognition; at Grade 3, word recognition and comprehension were essentially independent. These findings are considered in the context of Frith's three-phase hypothesis of reading acquisition. A rationale for testing the potential of training in auditory segmentation to modulate the effects of developmental dyslexia is presented.     

Inter-letter spacing,inter-word spacing,and font with dyslexia-friendly features: testing text readability in people with and without dyslexia

Over the last years, several studies have suggested a possible link between dyslexia and deficits in low-level visual processing (e.g., excessive crowding). At the same time, specially designed “dyslexia-friendly” fonts appeared on the market. This class of fonts presents two main features: the particular graphic characteristics of the letterform designed to avoid confusion between similarly shaped letters, and wider inter-letter and inter-word spacing to limit crowding. The literature testing the efficacy of “dyslexia-friendly” fonts in improving reading accuracy and increasing reading speed is controversial. We evaluated the impact of letterform (with vs. without dyslexia-friendly graphic features), inter-letter spacing (standard vs. increased), and inter-word spacing (standard vs. increased) on reading accuracy and speed. Two groups of 64 children each, with and without dyslexia, read aloud 8 equivalent texts. The data collected failed to show any effect from the letterform. As regards spacing, the data showed that reading speed is impaired by an increase in inter-letter spacing not combined with an adequate increase in inter-word spacing.     

Influence of increased letter spacing and font type on the reading ability of dyslexic children

Recent research studies have shown that increased letter spacing has a positive effect on the reading ability of dyslexic individuals. This study aims to investigate the effect of spacing on the readability of different fonts for children with and without dyslexia. Results did not support the hypothesis of better performance among children with dyslexia when reading text in Dyslexie than in other fonts. They, however, revealed that only spacing plays a role in enhancing dyslexic individuals’ reading performance because Dyslexie and the Times New Roman interspaced font have no difference. Furthermore, the negative effect of the unfriendly fonts Times New Roman Italic and Curlz MT was eliminated through increased interletter spacing.     

The effects of reading practice with compressed speech on reading rate and listening comprehension

Conclusions Reading practice with accompanying compressed speech as a pacer resulted in a significantly greater increase in reading rate without an accompanying loss in comprehension for the experimental group when compared with the control group. Scores on the delayed posttest seemed to indicate that the increase in reading rate was more than temporary. The significant increase in reading rate was accomplished with only 10 practice sessions. The number of sessions in earlier studies using pacers ranged from 16 (Marvel, 1959) to 50 (Wilson & Leavell, 1956). The present study suggests that a smaller number of sessions using compressed speech as a pacer can be effective in increasing reading rate. Since there was no significant difference between gain scores for the experimental and control groups for listening, this study provided no evidence to support the use of practice with compressed speech to improve listening ability. It might be noted however that the training sessions consisted of reading short storieswhile listening to the compressed speech. Thus, subjects did not receive practice in which listening to compressed speech was the sole activity. It is perhaps for this reason that the experimental group did not improve more in listening than did the control group. This article is based in part on Thameśs masteŕs thesis which was completed at the University of Wisconsin-Milwaukee.     

A review of a reading class placement for children with dyslexia,focusing on literacy attainment and pupil perspectives

This research investigated a special reading class placement for children with dyslexia in the Republic of Ireland. The study compared the literacy attainments of children before and after their reading class placement, and determined in particular children’s views regarding the placement. Participants included 16 children with dyslexia who had completed at least two years or maximum three years in a reading class for children with dyslexia, as well as 14 reading class and mainstream teachers. A case study was utilised to examine the three reading classes using a variety of data collection procedures including standardised assessment results, focus group and group interviews over a sustained period of time. Results indicated that children and teachers were very positive about the placement for children with dyslexia, with both children and teachers reporting academic, social, emotional, behavioural and attitudinal gains for the children in these classes. Findings from quantitative data demonstrated that children made progress in the areas of reading accuracy, comprehension and spelling, during their placement. Interestingly, findings from this study confirm that children who spent three years in the reading class made greater progress in the areas of reading accuracy and reading comprehension than children who spent two years in the reading class. However, there was no significant difference in the spelling achievement gains for children who attended the reading class placement for either two or three years. The qualitative findings revealed children’s increased positive disposition towards their own learning experiences during the special reading class placement and this was reported by both children and teachers alike. However, issues regarding lack of collaborative opportunities between mainstream and reading class teachers, and differentiation of curriculum content in the mainstream classroom remained throughout the placement period.     

Phonological and lexical reading in Italian children with dyslexia

In this study we explore the development of phonological and lexical reading in dyslexic children. We tested a group of 14 Italian children who have been diagnosed with dyslexia and whose reading age is end of grade 1. We compared this group with a group of 70 typically developing children who have been tested for reading at the end of grade 1. For each dyslexic child we also selected a participant who was attending the same grade, was close in age, and showed typical reading development when tested with a narrative passage reading task (Cornoldi, Colpo, & Gruppo MT, 1981) for correctness and reading speed. Children in this group are “same grade controls.” We used a reading task consisting of 40 three syllables words. A qualitative and quantitative method of coding children’s naming allowed us to distinguish several components of their reading performance: the grapheme and word recognition, the size of orthographic units involved in the aloud orthography–phonology conversion, the reading process used to recognize words. The comparison of the dyslexic group with the reading age and the same grade control groups reveals different trends of delayed reading processes. Considering dyslexic children’s chronological age, lexical reading is greatly delayed. Considering dyslexic children’s reading age, the type of reading process that is more deeply delayed is phonological reading. The rate of fragmented phonological reading (i.e., a type of syllabized phonological reading) is much higher in dyslexic children compared to the reading age group, suggesting that some factors undermine the possibility of internalizing the orthography–phonology conversion and the blending processes.     

Students with reading difficulties/dyslexia: a longitudinal Swedish example

The aim of this study was to investigate the longitudinal development of students having difficulties with reading and their decoding ability in Swedish compulsory school. Another aim was to relate this to the experiences of educational activities expressed by students and parents. The decoding ability was assessed by a word chain test given at three occasions and was compared with results on a letter chain test. Retrospective interviews were performed with students and parents. The decoding ability tended to improve for most of the students over time, although some of them failed to improve or even decreased their scores, indicating a lack of environmental adjustment. Special educational support was according to students and parents organised in small and often very heterogeneous groups where the students sometimes received adequate support but often felt deviant from friends in their regular classes. The responsibility for helping the children with their schoolwork was allocated to the parents. Research in this area demonstrates the necessity of a well‐structured and stimulating learning situation. Yet, the development of these students’ decoding abilities, personal experiences, and parental involvement indicate that competence and resources at school regarding children at risk for developing reading difficulties are often lacking in the Swedish educational system.
