Role of Auditory Cortical Oscillations in Speech Processing and Dyslexia

Dyslexia

This study aims at investigating the role of low-gamma activity in phonemic encoding and its implication in dyslexia. Indeed, a phonological deficit, i.e. a difficulty in perceiving the sounds of speech, is strongly suspected in dyslexia but has never been conclusively associated with a specific underlying mechanism. The study employs transcranial alternating current stimulation in adults with and without dyslexia to exploit the effect of the stimulation on phonemic processing and neural activity measured with electroencephalography. In doing so, it would be possible to establishing a causal link between gamma oscillations and the phonological deficit in dyslexia.

Developmental Dyslexia and Remediation Methods

DyslexiaDevelopmental

At least, three theoretical frameworks are currently involved in therapeutic research in developmental dyslexia. Each theoretical framework relies on the type of underlying cognitive processes that is viewed as impaired: 1°) phonological processing, 2°) cross modal integration, 3°) visual attention processing. In this controlled and randomized study, three types of computerized training are combined in a multi-factorial remedial approach in 8 to 12 year old children with dyslexia. The main objective is to compare the effectiveness of this remedial approach which combines phonological, visual-attentional and cross-modal training with conventional non-intensive and non-specific rehabilitation

The Baltimore Reading and Eye Disease Study

Refractive ErrorVisual Impairment2 more

The Baltimore Reading and Eye Disease Study (BREDS) is a two year study to determine the prevalence of vision problems in an early school age population with reading difficulty. Comprehensive vision and reading tests will be administered to 400 students at participating schools in the Baltimore City Public School system. A secondary goal is to examine the impact of vision treatment on reading performance. Children with refractive error or convergence insufficiency will be provided treatment free of charge. The investigators will evaluate the impact that the treatment has on vision function and reading performance.

Evidence-Based Interventions to Enhance Outcomes Among Struggling Readers

Reading DisabilityAnxiety

Despite decades of research on reading disabilities, little is known about improving reading in the middle grades (i.e., grades 3-6) and advancements have been hindered by the narrow focus on reading problems alone without acknowledgement of non-academic factors shown to affect learning (e.g., child self-regulation). This proposal employs a highly innovative approach aimed at improving intervention outcomes through the integration of evidence-based practices for addressing reading, as well as self-regulation/socioemotional skills, difficulties known to occur in a substantial percentage of struggling readers and to negatively influence academic performance. This project represents translational research that directly informs the practice community (schools, clinicians, teachers, parents), by identifying novel instructional practices that can be aggregated to more effectively influence student outcomes and reduce disparities in academic and socioemotional domains.

Developmental Dyslexia

The aim of the study is to compare the effectiveness of telerehabilitation vs. in presence rehabilitation of reading disorders, using a rhythm-based intervention for reading (i.e., Rhythmic Reading Training)

Effects of Music Education for Children With Reading Difficulties

Difficult; SpellingWith Reading Disorder

The main objective of this study is to evaluate the effectiveness of music education over a period of five months (three times per week, one hour per day) on the improvement of reading skills (decoding, prosody and phonological awareness) in children (8-10 years) with reading difficulties from poor neighborhoods in the city of Sao Paulo. A second objective is to develop a theoretical model that may explain how acquired musical skills are correlated with the supposed changes in each of the covariates and outcomes in this study. The study will be administered to 270 children with reading difficulties from 10 different schools (27 children per school). 135 children will have music lessons and 135 will not; therefore, 5 schools will be the control and 5 schools will be the intervention group. The analysis will consider the cluster structure, since the randomization was not conducted at the individual level (i.e., the school level was the randomization unit). For the inferential analysis, generalized estimation models and structural equation modeling will be used.

Rhythmic Reading Training: Comparing the Rhythmic and Visual Contributions to Reading Improvement...

Developmental Dyslexia

The main objective of the study is to evaluate the specific effect of the sub-components of the reading training program Rhythmic Reading Training (RRT) on reading speed and accuracy in a sample of Italian students with developmental dyslexia (DD). More precisely, in order to better understand the neuropsychological mechanisms involved in reading improvements following RRT, the specific contribution of the visual component of the training (presence of a visual cue) will be investigated in a study with between-groups design.

Eye Movements and Reading Disabilities

Reading DisabilityDyslexia

The mechanism of the eye movement anomalies seen in dyslexic patients is not well defined. Some optometrists use observational eye movement tests as screening devices for dyslexia and advocate eye movement therapy as a treatment option for dyslexia. The reliability of the clinical eye movement tests and the efficacy of the eye movement therapies have not been determined. Saccades are the fast eye movements that move our eyes from one word to the next when we read. The eye movement recordings from patients diagnosed with reading disorders, extra ocular muscle imbalances and control patients (no learning disability or eye movement disorder) will be analyzed and compared. The sensitivity and specificity of detecting reading disorders will be determined for the Visagraph III and the Readalyzer. Although these clinical tests are frequently used to diagnose saccadic inaccuracies and diagnose dyslexia in school aged children, the validity of these clinical screening tests has not been determined.

Dyslexia, Motor Control and Proprioception

Dyslexia

The investigators hypothesize that children with dyslexia present proprioceptive disorders and the purpose of the present study is to better understand relationships between motor control, proprioception and academic learnings. The investigators compare a group of French students with and without dyslexia aged 10-12.
