In this work, two different studies are examined to evaluate the effectiveness of a novel intervention program for the improvement of reading ability in children with dyslexia, known as repeated reading with vocal music masking (RVM). The proposed remedial approach is inspired by Breznitz’s original work. The studies assess a 5-week program of inte...
Individuals with dyslexia often present phonological difficulties, ultimately impacting their reading and writing. Nevertheless, an individual with dyslexia may circumvent these difficulties through a reliance on linguistic units with more consistent spellings, such as morphemes. The increased use of morphological information by individuals with dy...
Objective
The focus of this study is on providing tools to enable researchers and practitioners to screen for dyslexia in adults entering university. The first aim is to validate and provide diagnostic properties for a set of seven tests including a 1-min word reading test, a 2-min pseudoword reading test, a phonemic awareness test, a spelling test...
It has been argued that university students with dyslexia compensate for their reading deficits by a neural re-organization of the typical reading network, where the lexical representations of words are (re-)structured according to semantic rather than orthographic information. To investigate the re-organization of neural word representations more...
Prediction has become a key concept for understanding language comprehension, language production, and more recently reading.Recent studies suggest that predictive mechanisms in reading may be related to domain-general statistical learning (SL) abilities that support the extraction of regularities from sequential input. Both mechanisms have been di...
Background: Individuals with dyslexia are at risk of poorer reading comprehension levels due to their reading fluency impairment. However, some of such individuals exhibit a resilient profile, achieving appropriate reading comprehension levels despite their impairment.
Aims: This study aimed to investigate how key cognitive skills, specifically voc...
For some people the experience of visual imagery is lacking, a condition recently referred to as aphantasia. So far, most of the studies on aphantasia rely on subjective reports, leaving the question of whether mental images can exist without reaching consciousness unresolved. In the present study, the formation of mental images was estimated in in...
Prediction has become a key concept for understanding language comprehension, language production, and more recently reading. Indeed, a growing number of studies have used statistical learning (SL) paradigms to investigate whether SL abilities can explain inter-individual differences in language processing and reading. The aim of the present study...
We examined the reliance on phonological decoding and morpho-orthographic decomposition strategies in developing and skilled readers of French. A lexical decision experiment was conducted where the critical stimuli were four types of nonwords, all derived from the same base word, such as the French word visage (face) in the following examples: (a)...

A lexical decision experiment was conducted where the critical stimuli were four types of nonword all derived from the same base-word, such as the French word visage (face) in the following examples: 1) pse...
The predictive brain has become a key concept in language research and prediction is a dominant theoretical framework for understanding how the brain works. Psycholinguistic and neuroimaging research highlights the importance of anticipatory mechanisms in language comprehension, language production, and reading. In addition, a growing number of stu...
Phonemic processing skills are impaired both in children and adults with dyslexia. Since phoneme representation development is based on articulatory gestures, it is likely that these gestures influence oral reading-related skills as assessed through phonemic awareness tasks. In our study, fifty-two young dyslexic adults, with and without motor impa...
This study had three goals: to examine the stability of deficits in the phonological and lexical routes in dyslexia (group study), to determine the prevalence of dyslexia profiles (multiple-case study), and to identify the prediction of phonemic segmentation and discrimination skills before reading acquisition on future reading level. Among a group...
Langage écrit : état des pratiques orthophoniques et de la recherche
La dyslexie développementale est caractérisée par des déficits persistants en fluence en lecture, en décodage grapho-phonémique et en production orthographique. Bien que l’observation de la persistance des troubles fasse consensus dans la littérature scientifique internationale, il existe également un consensus sur l’observation d’un niveau hétérog...
The noisy computation hypothesis of developmental dyslexia (DD) is particularly appealing because it can explain deficits across a variety of domains, such as temporal, auditory, phonological, visual and attentional processes. A key prediction is that noisy computations lead to more variable and less stable word representations. A way to test this...
Developmental dyslexia is a specific learning condition characterized by severe and persistent difficulties in written word recognition, decoding and spelling that may impair both text reading fluency and text reading comprehension. Despite this, some adults with dyslexia successfully complete their university studies even though graduating from un...
Dans la présente étude, nous avons administré sur un échantillon de 56 adolescents dyslexiques et 39 adolescents normo-lecteurs (âgés de 12 à 18 ans) un ensemble de 7 tests évaluant les compétences phonologiques, en lecture et en orthographe. La prévalence des déficits a été étudiée par des analyses de cas. Une analyse de classification (i.e., arbr...

Objectives
The aim of this study was twofold. First, to confirm the deleterious aspect of evening screen exposure in school-aged children, in particular the effect of screens in the bedroom. Second, to explore the three-way association between degree of screen exposure, sleep disturbance, and ADHD symptoms. Strong evidence exists on the link betwee...
Ce livre rassemble les meilleurs spécialistes internationaux autour de la dyslexie à l'âge adulte. Il présente entre autres des outils cliniques destinés à identifier et diminuer les effets de la dyslexie au quotidien.
La dyslexie développementale est un trouble de la lecture et de l’orthographe qui affecte de 6 à 8 % de la population française. Le...
The Orthographic Depth Hypothesis [Katz, L., & Frost, R. (1992). The reading process is different for different orthographies: The orthographic depth hypothesis. In R. Frost & L. Katz (Eds.), Orthography, phonology, morphology, and meaning (pp. 67–84). Amsterdam: Elsevier Science] proposes cross-linguistic differences in the involvement of lexical...
Developmental dyslexia is a long-lasting reading deficit that persists into adulthood. In spite of many difficulties, some adults with dyslexia reach levels of reading comprehension similar to those of unimpaired readers and successfully study at university. While digital technologies offer many potential tools to facilitate reading, there are diff...
Objectif
La lumière des écrans retarde la production vespérale de mélatonine perturbant ainsi le sommeil de l’enfant consommateur d’écrans le soir. Cette étude a pour objectifs de :
– confirmer l’aspect délétère de l’exposition des 6–16 ans aux écrans le soir sur le sommeil et vérifier que l’exposition matinale est moins nocive ;
– examiner le lien...
La lecture d’une BD constitue une situation écologique intéressante pour étudier l’impact d’une réécriture tenant compte des facteurs d’espacement, taille des lettres, mots courts, phrases courtes, lignes brèves, sur la compréhension de lecteurs dyslexiques adultes. Nous appliquons ces contraintes de rédaction à un roman graphique italien et à sa t...
Depuis quelques années, les demandes d’un bilan orthophonique du langage écrit pour des aménagements pédagogiques et/ou de tiers-temps aux examens de l’enseignement supérieur sont de plus en plus fréquentes. Le laboratoire d’étude des mécanismes cognitifs de Lyon (69) et le laboratoire de psychologie cognitive de Marseille (13) ont récemment validé...
Developmental dyslexia is a lifelong impairment affecting 5 to 10% of the population. In French-speaking countries, although a number of standardized tests for dyslexia in children are available, tools suitable to screen for dyslexia in adults are lacking. In this study, we administered the Alouette reading test to a normative sample of 164 French...
Children from low-SES families are known to show delays in aspects of language development which underpin reading acquisition such as vocabulary and listening comprehension. Research on the development of morphological skills in this group is scarce, and no studies exist in French. The present study investigated the involvement of morphological kno...
A phonological deficit constitutes a primary cause of developmental dyslexia, which persists into adulthood and can explain some aspects of their reading impairment. Nevertheless, some dyslexic adults successfully manage to study at university level, although very little is currently known about how they achieve this. The present study investigated...
The spatiotemporal dynamics of morphological, orthographic, and semantic processing were investigated in a primed lexical decision task in French using magnetoencephalography (MEG). The goal was to investigate orthographic and semantic contributions to morphological priming and compare these effects with pure orthographic and semantic priming. The...

Most studies in adults with developmental dyslexia have focused on identifying the deficits responsible for their persistent reading difficulties, but little is known on how these readers manage the intensive exposure to written language required to obtain a university degree. The main objective of this study was to identify certain skills, and spe...
Previous research has repeatedly revealed evidence for morpho-orthographic priming effects in suffixed words. However, evidence for the morphological chunking of prefixed words is sparse and ambiguous. The goal of the present study was to directly contrast the processing of prefixed and suffixed pseudowords within the same experiment. We carried ou...
