Action video game training improves text reading accuracy, rate and comprehension in children with dyslexia: a randomized controlled trial.

Dynamic visual attention training using Action Video Games (AVGs) is a promising intervention for dyslexia. This study investigated the efficacy of 5 h (10 × 30 min) of AVG training in dyslexic children (aged 8-13) using 'Fruit Ninja', while exploring whether increasing attentional and eye movement demands enhanced AVG effectiveness. Regular (AVG-R; n = 22) and enhanced AVG training (AVG+; n = 23) were compared to a treatment-as-usual comparison group (n = 19) on reading, rapid naming, eye movements and visuo-temporal processing. Playing 'Fruit Ninja' for only 5 h significantly improved reading accuracy, rate, comprehension and rapid naming of both AVG groups, compared to the comparison group, though increasing attentional demands did not enhance AVG efficacy. Participants whose low contrast magnocellular-temporal processing improved most following training also showed significantly greater improvement in reading accuracy. The findings demonstrate a clear role for visual attention in reading and highlight the clinical applicability of AVGs as a fun, motivational and engaging intervention for dyslexia.

Small-world EEG network analysis of functional connectivity in developmental dyslexia after visual training intervention.

Aberrations in functional connectivity in children with developmental dyslexia have been found in electroencephalographic studies using graph analysis. How training with visual tasks can modify the functional semantic network in developmental dyslexia remains unclear. We investigate local and global topological properties of functional networks in multiple EEG frequency ranges based on a small-world propensity method in controls, pre- and post-training dyslexic children during visual word/pseudoword processing. Results indicated that the EEG network topology in dyslexics before the training was more integrated than controls, and after training - more segregated and similar to that of the controls in the theta (θ: 4-8), alpha (α: 8-13), beta (ß1: 13-20; ß2: 20-30), and gamma (γ1: 30-48; γ2: 52-70 Hz) bands for three graph measures. The pre-training dyslexics exhibited a reduced strength and betweenness centrality of the left anterior temporal and parietal regions in the θ, α, ß1 and γ1-frequency bands, compared to the controls. The simultaneous appearance of hubs in the left hemisphere (or both hemispheres) at temporal and parietal (α-word/γ-pseudoword discrimination), temporal and middle frontal cortex (θ, α-word), parietal and middle frontal cortex (ß1-word), parietal and occipitotemporal cortices (θ-pseudoword), identified in the EEG-based functional networks of normally developing children were not present in the networks of dyslexics. The hub distribution for dyslexics in the θ, α, and ß1 bands became similar to that of the controls. The topological organization of functional networks and the less efficient network configuration (long characteristic path length) in dyslexics compared to the more optimal global organization in the controls was studied for the first time after remediation training.

Intervención logopédica en trastornos del aprendizaje de la lectura en población infantil bilingüe / Speech therapy intervention in reading learning disabilities in bilingual children

ANTECEDENTES Y OBJETIVO: Con la mitad de la población mundial expuesta a más de una lengua, la escasez de estudios sobre la eficacia de intervenciones específicamente dirigidas a niños bilingües con trastorno del aprendizaje de la lectura (TAL) puede llevar al profesional a emitir recomendaciones precipitadas para su abordaje. El presente trabajo pretende aportar orientaciones para el diseño de intervenciones adaptadas a este tipo de usuarios. PACIENTES: Las orientaciones de intervención propuestas se dirigen a niños o adolescentes que evolucionan en contextos multilingües (con dos o más lenguas en su entorno familiar, escolar o social, que se juzguen relevantes para el desarrollo del individuo). RESULTADOS: Partiendo de la evidencia sobre la eficacia de las intervenciones fundamentadas en el desarrollo fonológico y de las correspondencias grafema-fonema con población multilingüe con trastorno del aprendizaje de la lectura, se proponen orientaciones para adaptar estos componentes del tratamiento a dicha población. Se incorporan asimismo recomendaciones de trabajo sobre componentes complementarios, tomando en cuenta su pertinencia en distintos tipos de lengua. CONCLUSIONES: La evidencia sugiere que es pertinente intervenir en más de una lengua con pacientes con trastorno del aprendizaje de la lectura, siempre y cuando se tengan en cuenta determinados aspectos específicos en el diseño del programa de intervención. No obstante, es necesario seguir generando estudios longitudinales de intervención o de caso con niños de distintos contextos multilingües, en función de la transparencia de cada una de sus lenguas, su momento de adquisición y el papel que desempeñan en la vida del niño

BACKGROUND AND OBJECTIVE: With half of the world's population exposed to more than one language, the lack of studies on the effectiveness of interventions specifically aimed at bilingual children with reading learning disorder can lead professionals to issue hasty recommendations on how to approach the issue. This paper aims to provide guidance for the design of interventions adapted to this type of users. PATIENTS: The proposed intervention guidelines are aimed at children or adolescents who evolve in multilingual contexts (with two or more languages in their family, school or social environment, deemed relevant for the development of the individual). RESULTS: Using the evidence of the effectiveness of interventions based on phonological development and grapheme-phoneme correspondences with multilingual population with reading learning disorder, guidelines are proposed to adapt these components of the treatment to said population. Recommendations for work on complementary components are also incorporated, taking into account their relevance in different types of language. CONCLUSIONS: The evidence suggests that it is pertinent to intervene in more than one language with patients with reading learning disorder, as long as certain specific aspects are taken into account in the design of the intervention programme. However, it is necessary to continue generating longitudinal intervention or case studies with children from different multilingual contexts, depending on the transparency of each of their languages, their moment of acquisition and the role they play in the child's life

An evaluation of systematized phonics on reading proficiency in Swedish second grade poor readers: Effects on pseudoword and sight word reading skills.

The aim of the present study was to evaluate the effect of systematized phonics on word reading in Swedish second grade poor readers. Forty-nine children who performed at or below the 25th percentile on pseudoword reading and/or sight word reading at the beginning of second grade participated in the study. The study had a cross-over design exploring within-and between-group effects of two different conditions: systematized phonics and classroom instruction. Overall, systematized phonics proved more effective than classroom instruction. At pre-intervention, no child performed above the 30th percentile in pseudoword reading or sight word reading. At post-intervention, corresponding numbers were 69% for pseudoword reading and 35% for sight word reading. Implications for a policy change in Sweden towards mandatory systematized phonics in primary school are discussed.

Is "Response/No Response" Too Simple a Notion for RTI Frameworks? Exploring Multiple Response Types With Latent Profile Analysis.

We conducted a secondary analysis of data from a randomized control trial to explore this question: Does "response/no response" best characterize students' reactions to a generally efficacious first-grade reading program, or is a more nuanced characterization necessary? Data were collected on 265 at-risk readers' word reading prior to and immediately following program implementation in first grade and in spring of second grade. Pretreatment data were also obtained on domain-specific skills (letter knowledge, decoding, passage comprehension, language) and domain-general skills (working memory, non-verbal reasoning). Latent profile analysis of word reading across the three time points with controls as a local norm revealed a strongly responsive group (n = 45) with mean word-reading z scores of 0.25, 1.64, and 1.26 at the three time points, respectively; a mildly responsive group (n = 109), z scores = 0.30, 0.47, and 0.55; a mildly non-responsive group (n = 90), z scores = -0.11, -0.15, and -0.55; and a strongly non-responsive group (n = 21), z scores = -1.24, -1.26, and -1.57. The two responsive groups had stronger pretreatment letter knowledge and passage comprehension than the two non-responsive groups. The mildly non-responsive group demonstrated better pretreatment passage comprehension than the strongly non-responsive group. No domain-general skill distinguished the four groups. Findings suggest response to early reading intervention was more complicated than response/no response, and pretreatment reading comprehension was an important predictor of response even with pretreatment word reading controlled.

Comparison of Reading Growth Among Students With Severe Reading Deficits Who Received Intervention to Typically Achieving Students and Students Receiving Special Education.

This study compared the reading growth of students with and without learning disabilities, and students with and without reading deficits in response to tier 2 reading interventions within a response-to-intervention framework. Participants were 499 second- and third-grade students in six urban schools. Students who scored at or below the 10th percentile on the fall reading screening assessment were identified as having a severe reading deficit and received a tier 2 reading intervention that was targeted to their needs. Results showed a significant effect between groups on reading growth. Students with severe reading deficits receiving targeted tier 2 intervention grew at a rate that equaled the rate of growth of students without reading deficits and was significantly higher than students who were receiving special education services for reading. Implications for practice, suggestions for future research, and study limitations are discussed.

The effects of book exposure and reading interest on oral language skills of children with and without a familial risk of dyslexia.

The potential role of home literacy environment (HLE) in children's language development has been widely studied. However, data on the HLE of children with familial risk (FR) of dyslexia are limited. In this longitudinal study, we examined (a) whether amount of book exposure and reading interest at age 4 were different in samples of Norwegian FR and no FR-children, respectively, (b) whether these home literacy-related factors exerted different effects depending on family-risk status on vocabulary and grammar skills at school entry age (6 years) and (c) whether they contributed independently to language outcomes at age 6, after controlling for the 4;6-year language skills. Results showed no significant between-group differences in book exposure and reading interest. Furthermore, while interest in reading did not affect vocabulary and grammar in either group, book exposure contributed to vocabulary skills only in the FR-group by school entry. However, this longitudinal association was mediated by lexical skills at age 4;6, implying that the HLE has a positive indirect effect on later language development through its effect on early language. Thus, these findings can be taken to suggest that early intervention including exposure to various book-reading activities for pre-school FR-children with poor expressive vocabulary is worth considering.

Proyecto Petit UBinding: método de adquisición y mejora de la lectura en primero de primaria. Estudio de eficacia / Petit UBinding project: An efficacy study of a reading acquisition and reading improvement method for first grade children

El objetivo de este estudio fue evaluar el impacto de un nuevo método educativo diseñado en la Universidad de Barcelona para dotar a los profesionales de material y herramientas para estimular la lectura en el alumnado de primer curso de educación primaria. Se realizó un diseño pre-post con niños/as separados en 2 grupos: experimental y control. El método fue aplicado en el grupo experimental de noviembre a abril. Tres veces por semana se administraron desde la escuela sesiones grupales en las que se trabajaba mayoritariamente la descodificación, el vocabulario y la comprensión. Por otro lado, de una a 4 veces por semana, según el nivel de eficiencia lectora detectado en cada alumno/a, se llevaron a cabo sesiones individuales online desde el domicilio de los participantes completamente adaptadas al nivel de cada alumno/a, en donde el objetivo principal era trabajar la descodificación. Los análisis mostraron que el grupo experimental obtuvo mejores resultados en fluidez lectora (velocidad y precisión) en todas las pruebas administradas comparado con el grupo de control a final de curso

The aim of this study was to measure the impact of a new method designed at the University of Barcelona to give professionals material and tools that could stimulate reading among first grade of primary school children. The children were split into two groups, an experimental and a control group, and their performances were evaluated within a pre- and post-design. The methodology was applied in the experimental group between November and April. Three times a week, children took part in group sessions that were organized at school. During these sessions, they mainly worked on decoding, vocabulary and comprehension. Between 1 and 4 times a week, according to the reading proficiency of each child, individual online sessions took place at home. These sessions, whose objective was to work primarily on decoding, were entirely adapted to meet the needs of each child, according to his/her level. The analysis of data showed that, at the end of the school term, the experimental group got better results in terms of reading fluency (speed and accuracy) in all tests assessed than the control group

Reading comprehension in dyslexic schoolchildren after an intervention program. / Compreensão de leitura em disléxicos após programa de intervenção.

PURPOSE: To develop a Speech-language Pathology (SLP) program and verify its effects on the reading comprehension of dyslexic students. METHODS: Participants were eleven 4th and 5th-grade Elementary School students, eight boys and three girls, aged 9-11 years, diagnosed with developmental dyslexia. All individuals underwent the therapeutic program, which was composed of 16 sessions divided into four levels of complexity. A text adapted according to the Cloze technique and reading comprehension and orthography tasks were used in each session. The schoolchildren had their reading comprehension assessed pre- and post-program using a text available at the Test of Reading Comprehension of Expository Texts, adapted for application of the structural Cloze technique without support, according to the Evaluation of Reading Comprehension Levels. RESULTS: The participants showed better performance in reading comprehension at the post-program assessment not only in the filling of blanks in the text adapted according to the Cloze technique and in the Responses to Reading Comprehension Questions, but also in the level of reading comprehension achieved. CONCLUSION: The SLP program improved the reading comprehension performance and increased motivation to reading of dyslexic schoolchildren. Both the Cloze technique and the Reading Comprehension Questions were useful tools to develop and identify changes in the reading comprehension of the students assessed. This study is relevant because it prepared and verified the effects of a specific remediation program for schoolchildren with dyslexia by proposing the use of texts adapted according to the Cloze technique combined with other various tasks of reading comprehension and orthography.

The Critical Role of Word Reading as a Predictor of Response to Intervention.

This study examines the initial word reading performance of fourth-grade struggling readers and the extent to which differing levels of word reading performance at pretest influenced their response to reading interventions. A large group of students with significant reading comprehension difficulties (N = 481) were classified into three clusters of word reading proficiency based on their pretest performance: (a) very low, (b) low, and (c) near adequate. We examined their performance on several academic, language, and executive functioning measures at the beginning of the year and their reading comprehension performance at the beginning of year and after 1 year of reading intervention to examine how each cluster responded to instruction. Results from a discriminant function analysis indicated that performance on five pretest variables were meaningful predictors of word reading proficiency cluster membership: phonological processing, writing fluency, math calculation, math fluency, and reading efficiency and comprehension. Results also demonstrated that word reading proficiency at pretest was related to response to intervention on reading comprehension measures. Students in the very low word reading proficiency cluster showed minimal response to intervention whereas the near-adequate word reading cluster demonstrated greatest response to intervention. These results suggest word reading is a critical predictor of response to intervention for students with significant comprehension problems in the upper elementary grades and that students with the most substantial word reading problems may require more intensive and specialized treatments than students with greater word reading performance to show meaningful progress in reading.

Intervention for a lexical reading and spelling difficulty in two Greek-speaking primary age children.

An intervention study was carried out with two nine-year-old Greek-speaking dyslexic children. Both children were slow in reading single words and text and had difficulty in spelling irregularly spelled words. One child was also poor in non-word reading. Intervention focused on spelling in a whole-word training using a flashcard technique that had previously been found to be effective with English-speaking children. Post-intervention assessments conducted immediately at the end of the intervention, one month later and then five months later showed a significant improvement in spelling of treated words that was sustained over time. In addition, both children showed generalisation of improvement to untrained words and an increase in scores in a standardised spelling assessment. The findings support the effectiveness of theoretically based targeted intervention for literacy difficulties.

The intelligibility and comprehension of synthetic versus natural speech in dyslexic students.

Introduction-Purpose: Despite the growing amount of data on the 'synthetic speech perception' by people with no disabilities, there has been limited research on the intelligibility and comprehension of synthetic speech systems by dyslexics. This study investigated the intelligibility and comprehension of synthetic versus natural speech in Greek dyslexic students.Method: Forty three dyslexic students were presented with various acoustic stimuli (words, sentences, texts) both in synthetic and natural speech.Results: The data analysis has shown that dyslexic students had identified better words and sentences presented in natural than in synthetic speech. In regards to their levels of performance in text comprehension there was not any significant difference between synthetic and natural speech. Perhaps their observed difficulties in their word/ sentence intelligibility did not manage to restrain their levels of text comprehensibility. It seemed as if the context cues provided by the text each time had assisted dyslexics in comprehending the text more effectively no matter the speech condition used (natural versus synthetic one).Conclusion: Given that the overall purpose of reading is comprehension it is suggested that the text to speech systems could be used after all by the dyslexics as support as scaffolds for the intended purpose of reading comprehension.Implications for rehabilitation This research constitutes a trial to investigate the possibility of text-to-speech technology to serve as an educational aid for students with reading deficits helping them to master reading tasks that they may not have been able to do on their own. Students with reading disabilities need to be more successful in the reading process and managing at the same time to decrease the achievement gap that exists between them and those without disabilities. This work suggests that:• Text-to-speech technology needs further development and improvement to provide a closer to natural speech output in order to be a valuable educational aid for students with dyslexia.• Although there is a deviation, especially, in intelligibility between synthetic and natural speech that kind of assistive technology could provide a useful educational aid for those students that reading tasks appear to be a cumbersome process.• Natural and synthetic speech in combination and in discriminating use (for instance, natural speech in word tasks and synthetic in contextual tasks i.e., reading texts) could be integral tools to numerous educational settings and rehabilitation bodies.

Both Individual and Group-Based Neuropsychological Interventions of Dyslexia Improve Processing Speed in Young Adults: A Randomized Controlled Study.

Effectiveness of individual and group-based neuropsychological interventions on cognitive aspects of dyslexia in young adults was evaluated. Dyslexic adults were randomly assigned into individual intervention (n = 40), group intervention (n = 40), or wait-list control group (n = 40). The interventions focused on cognitive strategy learning, supporting self-esteem, and using psychoeducation. Cognitive performance and symptoms were assessed via psychometric testing and self-report questionnaires at baseline, after the intervention/wait-list control time at 5 months and at 10 months. And, 15 months post intervention long-term status was checked via mailed inquiry. Wait-list control group also received an intervention after the 5-month control period. No significant effects were found in primary self-report outcome measures. Both interventions had a positive effect on a measure of processing speed and attention and the effect remained after the 5-month follow-up period. In self-reported cognitive symptoms, a positive trend was evident in self-reported reading habits. Furthermore, minor self-evaluated benefits reaching up to 15 months post intervention were found. There were no significant differences between the results of individual and group intervention as both interventions improved cognitive performance. The results indicate that a structured neuropsychological intervention could be effective in ameliorating dyslexia-related cognitive symptoms in young adults.

Teaching Grapheme-Phoneme Correspondences Using a Direct Mapping Approach for At-Risk Second Language Learners: A Randomized Controlled Trial.

Reading interventions developed to teach grapheme-phoneme correspondences (GPCs) were evaluated among L2 at-risk readers. In the direct mapping of grapheme (DMG) condition, children's attention was explicitly drawn to the application of a graphemes taught on that day to shared reading of words in authentic text. In the control condition there was no such systematic daily linkage of the GPCs and texts. The two reading interventions were otherwise identical. Two hundred fifty-three Chinese Grade 1 and Grade 2 students were screened, and those who scored in the bottom 30% of an English word-reading test were identified as L2 at-risk readers. Seventy-one L2 at-risk readers were thus randomly assigned to two conditions, both of which were small-group reading interventions: (a) DMG or (b) taught control. We hypothesized a significant main effect of Intervention condition and significant interaction of Intervention by Phonological Awareness (PA) effects on word reading, word attack, spelling, and sentence comprehension favoring the DMG intervention. Results showed that predicted interaction effects were significant for word reading, spelling, and sentence comprehension. No other effects were significant. Results suggest that the daily Direct Mapping of taught GPCs to shared book reading promotes reading development in at-risk English L2 readers with stronger phonological skills.

A Synthesis of Elementary Mathematics Interventions: Comparisons of Students With Mathematics Difficulty With and Without Comorbid Reading Difficulty.

In this synthesis, we reviewed 65 studies involving elementary students (i.e., grades 1-5) identified with mathematics difficulty (MD) in which authors implemented a mathematics intervention. Of these studies, we identified 33 group designs, 9 quasi-experimental designs, and 23 single-case designs. We aimed to synthesize performance differences between students with MD with and without reading difficulty (RD). We identified three categories of students for analysis: Students with MD+RD, MD-alone, or MD-nonspecified (i.e., no reading information provided). Overall, 80% of studies included students with MD-nonspecified, and the interventions for these students demonstrated strong effects. For the limited number of studies with students with MD+RD or MD-alone, intervention effects were strong for students with MD+RD and variable for students with MD-alone. In the three studies directly comparing the performance of students with MD+RD versus MD-alone, we noted differential patterns of performance. To tailor interventions to student need, more research must be conducted to understand whether students with MD with variable reading profiles respond differentially to mathematics intervention.

Spoken Word Learning Differences Among Children With Dyslexia, Concomitant Dyslexia and Developmental Language Disorder, and Typical Development.

Purpose The purpose of our study was to test the hypotheses (a) that children with dyslexia have spoken word learning deficits primarily related to phonology and (b) that children with dyslexia and concomitant developmental language disorder (DLD) have word learning deficits related to both phonology and semantic processing when compared to peers with typical development (TD). Method Second-graders with dyslexia (n = 82), concomitant dyslexia and DLD (dyslexia + DLD; n = 40), and TD (n = 167) learned names and semantic features for cartoon monsters in 5 carefully controlled word learning tasks that varied phonological and semantic demands. The computer-based tasks were played in 6 different word learning games. We analyzed results using Bayesian statistics. Results In general, the dyslexia + DLD group showed lower accuracy on tasks compared to the dyslexia and TD groups. As predicted, word learning tasks that taxed phonology revealed deficits in the dyslexia group, although there were some exceptions related to visual complexity. Word learning deficits in the dyslexia + DLD group were present in tasks that taxed phonology, semantic processing, or both. Conclusions The dyslexia + DLD group demonstrated word learning deficits across the range of word learning tasks that tapped phonology and semantic processing, whereas the dyslexia group primarily struggled with the phonological aspects of word learning.

ReadClear: An Assistive Reading Tool for People Living with Posterior Cortical Atrophy.

BACKGROUND: Progressive reading impairment is an early and debilitating symptom of posterior cortical atrophy (PCA) arising from the progressive deterioration of visual processing skills. OBJECTIVE: The goal of this study was to test the effectiveness of a purpose-built reading app (ReadClear) co-produced with people living with PCA and designed to reduce the reading difficulties experienced by this population (e.g., getting lost in the page and missing words when reading). METHODS: Twenty subjects with PCA were included in a cross-over design home-based study aimed at determining whether ReadClear could 1) enhance the subjective reading experience (reading pleasantness) and 2) improve reading accuracy (reducing the number of reading errors) compared with a sham condition (a standard e-reader). RESULTS: Reading using ReadClear provided a better subjective reading experience than sham (p = 0.018, d = 0.5) and significantly reduced the percentage of reading errors (p < 0.0001, r = 0.82), particularly errors due to omissions (p = 0.01, r = 0.50), repeated words (p = 0.002, r = 0.69), and regressions in the text (p = 0.003, r = 0.69). We found that different kinds of reading errors were related to specific neuropsychological profiles. CONCLUSION: ReadClear can assist reading in people living with PCA by reducing the number of reading errors and improving the subjective reading experience of users.

Longitudinal Effects of Reading and/or Mathematical Difficulties: The Role of Special Education in Graduation From Upper Secondary Education.

This study explores the long-term effects of difficulties in reading and mathematical skills on educational achievement and successful graduation from secondary education as well as the role of special education in successful graduation. Study participants were all 16-year-old ninth graders from one Finnish city (N = 595; 302 females, 293 males) who were followed for 5 years after completing compulsory education. Students' reading and mathematical skills were measured at the end of compulsory education and their achieved grades in literacy and mathematics were received from their upper secondary schools. The overall results show that although part-time special education was available throughout both compulsory and upper secondary education, the negative longitudinal consequences of reading difficulties (RDs) and mathematical difficulties (MDs) on school achievement in literacy, mathematics, and rates of graduation can be seen. The regression path models were estimated separately for female and male students and show that among male students with RDs and MDs, the part-time special education that students received in Grades 7 to 9 was significantly related, but for Grades 10 to 11, this relationship is only significant among students with RDs. Moreover, low levels of school achievement in literacy among female students and in literacy and mathematics among male students significantly increased the likelihood of delayed graduation.

Visual statistical learning and orthographic awareness in Chinese children with and without developmental dyslexia.

This study examined the role of visual statistical learning in reading and writing and its relationship to orthographic awareness in Hong Kong Chinese children with and without developmental dyslexia. Thirty-five 7- to 8-year-old children with developmental dyslexia and 37 chronologically age-matched controls were tested on visual statistical learning, orthographic awareness, nonverbal cognitive ability, Chinese word reading, and word dictation tasks. Visual statistical learning was assessed using a triplet learning paradigm that required children to detect the temporal order of visual stimuli. Orthographic awareness was measured with a novel character invention task that required children to create pseudocharacters using untaught stroke patterns according to the rules of Chinese character orthography. Children with dyslexia performed significantly worse than their age-matched controls on both the visual statistical learning and orthographic awareness tasks. Furthermore, visual statistical learning was significantly associated with orthographic awareness and word reading. These findings suggest that Chinese children with dyslexia are impaired in visual statistical learning and that such deficits may be related to disrupted orthographic learning abilities, thereby contributing to their reading difficulties.
