Les enfants et adolescents dysphasiques présentent un trouble spécifique du langage qui se manifeste, en absence d'un déficit cognitif, sous la forme d'une perturbation profonde à l'oral et qui persiste au-delà de l'âge de 6 ans. Basée sur des éléments de psychologie pragmatique développementale (principe de coopération de Grice, 1979, et passage de la phase inter-psychologique à la phase intra-psychologique de Vygotski, 1997), et inspirée des travaux de Berman (2005), cette thèse défend l'idée que dans la dysphasie le langage n'est pas uniformément déficitaire. En d'autres termes, les performances langagières des enfants et des adolescents dysphasiques devraient varier en fonction de la situation de production dans laquelle ils se trouvent (tache standardisée vs. tache communicative), mais aussi en fonction de la modalité de production (oral vs. écrit), et enfin de l'indice linguistiques considéré (e.g. orthographe lexicale vs. orthographe morphologique). Les résultats obtenus montrent que les dysphasiques ont de meilleures performances langagières en situation de communication qu'en situation standardisée, que leurs performances en situation communicative sont meilleures à l'écrit qu'à l'oral, et enfin que le profil développemental de leurs capacités langagières évolue différemment, entre 7-11 ans et 12-18 ans, selon l'indice linguistique considéré. La psychologie pragmatique développementale permet donc de souligner que, dans le cadre de l'évaluation des capacités langagières des enfants et des adolescents dysphasiques, le choix des tâches influence les performances obtenues. De plus, comme le préconisait Ringard (2000), les enfants et adolescents dysphasiques bénéficient pleinement d'une scolarisation en milieu ordinaire et y progressent sur le long terme. / Children and adolescents with a specific language impairment (SLI) present a language disorder that appears in the absence of a cognitive impairment and persists beyond the age of 6. Based on elements of developmental pragmatics (Grice cooperative principle, 1979 and transition from the interpsychological to intrapsychological functioning, Vygotsky, 1997) and inspired by the work of Berman (2005), this thesis defends the idea that in SLI the language is not a uniform deficit. In other words, the language performances of children and adolescents with SLI should vary according to the situation in which they produce language (standardized test vs. communicative situation), but also according to the production modality (oral vs. written), and finally the linguistic measure considered (e.g. morphological spelling vs. lexical spelling). The results show that the participants with SLI perform better in a communicative than in a standardised test situation, and in written than in spoken language. Finally, their performance varies differently according to the measure considered, from 7 to 11 and 12 to 18. The developmental pragmatics framework chosen made it possible to emphasize that, when assessing language abilities in children and adolescents with SLI, the choice of a task affects the performance obtained. Moreover, as advocated by Ringard (2000), children and adolescents with SLI fully benefit from a mainstream school environment, where they can progress in the long term, up to the age of 18.

<p>This work presents two studies of language processing and development in children. The first study focuses on passive sentence comprehension in 4-5-year-old children with developmental language disorder (DLD) and same-age peers with typical development (TD). We explore the effect of animacy, morphosyntactic, vocabulary, and event probability cues on children’s offline comprehension and online processing of passive sentences using an eye-tracked looking-while-listening design. The children were first exposed to short videos of agents doing characteristic actions (e.g., hard physical activities or passively observant activities). The children then engaged in an eye-tracked online processing task in which they heard reversible and nonreversible passive sentences describing events that matched or did not match the characteristics set up in the exposure videos. During these sentences, images on-screen were displayed that corresponded to the potential interpretations of the sentence. Online processing data was collected using eye tracking. After each sentence, the children were asked to point to the image corresponding to their interpretation to measure their offline comprehension. The offline comprehension data indicated that compared to the children with TD, the children with DLD were less likely to correctly interpret the passive sentences and made comprehension errors that suggested poorer attention to and integration of potentially informative sentence cues. The eye-tracked online processing data was examined in two ways. First, we analyzed the online processing data to determine to what extent the children’s processing was consistent with the use of the sentence cues. We found that the children in the two groups were just as likely to demonstrate looking patterns consistent with the use animacy cues but children with DLD were less likely to use morphosyntactic, vocabulary, and event probability cues. We then analyzed the online processing data in correctly interpreted sentences only to examine how the sentence cues were integrated over the course of the sentence. We found that in correctly interpreted sentences, children with DLD demonstrated a slower, less robust response to most of the informative cues in the sentences but quicker and less linguistically mediated use of event probability cues. Finally, we examined the relationship between the children’s use of event probability cues and their stimuli-specific vocabulary knowledge but found no strong associations. </p><p><br></p><p> The second study focuses on the semantic network structure of the vocabularies of young 18-30-month-old children and its influence on noun and verb learning. Prior work had examined how noun semantic network structure affects noun learning. Here, we extended that work to ask how noun and verb semantic network structures differ in their influence on noun and verb learning. We examined vocabulary network structure at the word, semantic neighborhood, and lexicon levels in a large sample of child vocabulary checklist data using semantic features. We analyzed the data in three ways. First, we charted the relationship between verb and noun semantic network structure and vocabulary size across children. We found that early-learned nouns tended to have strong network relationships with other nouns and other verbs across network levels. We also found that early-learned verbs tended to have strong network relationships with other nouns but, in contrast, were unlikely to have strong relationships with other verbs. Next, we examined patterns of normative vocabulary development, asking whether the cross-sectional patterns seen in the first analysis influenced the time at which nouns and verbs tended to be learned. We found similar patterns. Nouns with strong semantic connections to other nouns and other verbs tended to be learned early. Verbs with strong semantic connections to other nouns tended to be learned early but verbs with strong semantic connections to other verbs tended to be learned later. Finally, in an effort to determine how the very earliest vocabulary knowledge sets the stage for later word learning, we examined how word knowledge gaps formed and were filled by nouns and verbs in normative vocabulary development. These gaps corresponded to structured “cavities” in the semantic networks. We found that nouns tended to form semantic cavities that were later filled by nouns and verbs, reinforcing the findings from the first analyses that early noun knowledge is a prerequisite for later verb learning. </p>

Syftet med denna uppsats är att öka kunskapen kring hur några lärare undervisar elever med språkstörning på låg-, mellan- och högstadiet. Syftet uppnås genom att intervjua lärare och på så sätt få svar på frågeställningarna: Hur anpassar lärarna undervisningen för elever med språkstörning samt vilka utmaningar upplever lärarna att eleverna har? Vilka assisterande verktyg har lärarna tillgång till och använder? I vilken utsträckning anser lärarna att de har kunskaper och tillgång till stöd för att anpassa undervisningen för elever med språkstörning? I undersökningen framkommer att lärarna gör anpassningar i klassrummet för att elever med språkstörning ska kunna nå kunskapsmålen, men att de känner sig osäkra på hur de på bästa sätt skall göra lämpliga anpassningar. De assisterande verktyg som eleverna har tillgång till är bland annat inläsningstjänst och talsyntes. Dessa assisterande verktyg upplevs av lärarna både som framgångsrika men samtidigt som problematiska då de kan innebära praktiska hinder och avleda uppmärksamheten. Trots att språkstörning påverkar både sociala relationer, skolnärvaro och självbild hos dessa elever upplever många lärare att de har bristande kunskap kring diagnosen språkstörning och framgångsrika arbetssätt.

La dysphasie consiste en une atteinte sévère et persistante de l’acquisition et du développement du langage oral. Les élèves qui en sont atteints peinent à devenir des lecteurs habiles et sont à haut risque d’échec scolaire. Si ce trouble très complexe est étudié dans différents domaines (la santé et l’éducation, entre autres), peu d’études se sont spécifiquement intéressées à vérifier si les élèves dysphasiques possèdent des connaissances morphologiques dérivationnelles. Or, depuis un certain nombre d’années, de nombreux chercheurs soutiennent que ces connaissances, qui concernent la forme des mots et leurs règles de formation, peuvent constituer une stratégie supplémentaire aidante pour les élèves aux prises avec un déficit phonologique, comme les élèves dysphasiques. C’est dans ce cadre que se situe la présente étude, dont l’objectif général est d’évaluer les connaissances morphologiques dérivationnelles d’apprentis-lecteurs dysphasiques francophones du primaire. Pour y parvenir, trois tâches morphologiques, soit une tâche de jugement de relation, une tâche de dérivation et une tâche de plausibilité, ont été soumises à trois groupes de participants dont un groupe d’élèves dysphasiques (D=30) et deux groupes contrôles, c’est-à-dire des élèves du même âge chronologique (CA, n=30) et des élèves plus jeunes, mais du même niveau de lecture (CL, n=30). Nos résultats montrent que l’ensemble des trois groupes de participants a tiré profit des unités morphologiques contenues dans les items pour réussir les tâches proposées, les dysphasiques obtenant des résultats inférieurs aux CA mais comparables aux CL. Toutefois, ces résultats ne s’apparentent pas tout à fait au continuum de développement des connaissances morphologiques dérivationnelles établi par Tyler et Nagy (1989). De plus, aucun effet du type d’affixation (items préfixés vs suffixés) n’a été observé. Les résultats obtenus nous permettent de proposer des pistes d’interventions orthodidactiques visant l’enseignement de la morphologie dérivationnelle auprès des élèves aux prises avec des difficultés de lecture, à l’instar des participants dysphasiques qui ont participé à cette étude. / Dysphasia, also known as specific language impairment, is a severe and persistent impairment of acquisition and development of oral language. Students struggling with dysphasia have reading issues and are at high risk of school failure. If this complex disorder is studied in different areas (health and education, among others), few studies have specifically focused on the evaluation of morphological knowledge of dysphasic students. Morphology refers to the study of the internal structure of words and to how small meaningful linguistic units, termed “morphemes”, can be combined to form words. Over the past 30 years, numerous studies have been published on morphological knowledge, showing that awareness of words’ morphological structure can be a very helpful tool for students who are regularly exposed to unfamiliar words and can contribute to reading comprehension, among other skills. From these observations, we conducted a study to investigate morphological knowledge in young French students with dysphasia. To achieve this, three morphological tasks were used among three groups of students including a group of dysphasic students (D=30) and two control groups (students of the same chronological age (CA=30) and younger students of the same reading level (CL=30)). Our results show that all groups of participants took advantage of the units of meaning contained in the words in order to succeed tasks. Results also indicate that D and CL performed similarly on three tasks, but were outperformed by the CA group. For all three groups, results are not following the morphological knowledge continuum suggested by Tyler and Nagy (1989). Moreover, our results show no effect of the type of affixation (prefixed items vs suffixed items). These results have implications for teaching practices, especially when teachers plan specific activities to teach derivational morphology to students struggling with reading difficulties.

This thesis solves deals with special pedagogical problems of primary literacy acquisition of the children with specific language impairment. The aim is to analyze the phenomena, which disrupt the process of acquiring written language forms of the pupils with this diagnosis and to record factors, which help to streamline this process. Another task is to propose the steps to help overcome the problems caused by impaired communication skills by teaching analytic-synthetic method. The theoretical part is the basis for meeting the targets. It describes specific language impairment as one of the categories of impaired communication skills and its consequences for education. Attention is given to the topic of literacy. Emphasis is particularly given on the initial reading literacy. This period is seen in the context of the speech development and the psycholinguistic concept of literacy is introduced, where the skill of phonemic awareness has a central position. At the end of the theoretical part, the methods of teaching of reading are described. The practical part presents the research study, which was carried out in several consecutive phases: initial diagnostic phase, observation of pupils in various stages of teaching of reading, implementation of methodical support measures and the final assessment of the...

Les grammaires de construction postulent l’émergence progressive des structures du langage via l’utilisation de processus cognitifs généraux. Les hypothèses théoriques qui en émanent suggèrent que la complexité et la structure des formes morphosyntaxiques ne peuvent s’expliquer que dans une perspective constructiviste, où l’enfant développe ses nouvelles formes en complexifiant et en généralisant ses propres productions antérieures. Ces hypothèses ont été éprouvées auprès de populations présentant un développement typique du langage (DTL) mais ont peu fait l’objet d’une mise en application auprès d’enfants avec troubles spécifiques du langage (TSL). Or, ces théories offrent de nouvelles perspectives théoriques permettant de mieux appréhender leurs difficultés langagières. Ces enfants présentent un manque de productivité syntaxique ainsi qu’une plus grande dépendance à l’input linguistique, allant dans le sens d’un manque de généralisation des schémas de construction. Nous suggérons que, contrairement aux enfants avec DTL, l’abstraction des schémas de construction des enfants avec TSL serait entravée en raison d’un mécanisme de généralisation qui se mettrait en place plus lentement. Ce travail de thèse a pour objectif de tester cette hypothèse chez les enfants avec TSL, en s’intéressant plus particulièrement au rôle du mapping analogique. Les résultats obtenus sont prometteurs et compatibles avec cette hypothèse. Si l’étude du mapping analogique comme facteur à l’origine des difficultés des enfants avec TSL est particulièrement séduisante, de nombreuses pistes restent à explorer pour appuyer davantage notre hypothèse. / Construction grammars argue that language structures progressively emerge thanks to the use of general cognitive processes. Theoretical hypotheses suggest that complexity and structure of morphosyntactic forms can only be explained in a constructivist perspective in which children develop their new forms by making more complex and generalizing their own prior utterances. These hypotheses have been already tested with children with typical language development (TLD) but few studies were interested in children with specific language impairment (SLI). These hypotheses give new interesting theoretical perspectives for apprehending their language disorders better. Children with SLI present a lack of syntactic productivity and a more important input dependency. These observations are compatible with the hypothesis of a lack of generalization of construction schemas. Consequently, the children’s abstraction of construction schemas would be slowed down compared to children with TLD’s abstraction. The current doctoral thesis studies the hypothesis of a lack of generalization in children with SLI by analyzing more particularly the role of analogical mapping. The results obtained are promising and in agreement with our hypothesis. If studies about the role of analogical mapping as a factor explaining the disorders in children with SLI are attractive, other considerations have still to be explored for strengthening our hypotheses.

Este estudo tem por objetivo investigar o comportamento das crianças com Distúrbio Específico de Linguagem (doravante DEL) em relação à produção de uma estrutura sintática complexa, a interrogativa QU de longa distância (doravante pergunta QULD) no português brasileiro, e compará-lo ao das crianças com Desenvolvimento Típico (doravante DT). Foram coletados dados desses 2 grupos de crianças (DEL e DT) entre 5 e 11 anos de idade. Utilizou-se a metodologia de eliciação, implantada em Thornton (1990), para realizar o experimento. Foram eliciadas 16 perguntas QU LD para cada criança, sendo que 8 dessas perguntas eram com extração de sujeito (4 QU nu e 4 QU+N) e 8 com extração de objeto (4 QU nu e 4 QU+N). Os dados da produção dos 2 grupos foram comparados e observou-se que as crianças de ambos os grupos dominam a estrutura de pergunta-QU LD a partir dos 5 anos. Contudo, a produção de tal estrutura sintática pelo grupo das crianças com DEL (36,65%) mostrou-se menos frequente do que a produção do grupo com DT (89,70%), sugerindo que o grupo com DEL enfrenta dificuldades com as estruturas complexas que envolvem movimento. Considerando-se a produção das crianças com DEL, as perguntas-QU de objeto foram produzidas a taxas semelhantes às perguntas QU de sujeito (QU-que simples de sujeito com movimento-QU (44,44%) e QU simples de objeto (55,55%)) pelo grupo com DEL. A análise dos dados nos sugere que as crianças com DEL, embora apresentem dificuldades relacionadas aos movimentos sintáticos, são capazes de processar ambas as estruturas, diferentemente do que outros estudos com essa população encontrou (por exemplo, Van der Lely e Battell (2003) e Friedmman e Novogrodsky, (2011)). Curiosamente, as crianças não produziram perguntasQU com QU in situ, embora a produção de tal estrutura fosse esperada como uma estratégia de minimização de custo de processamento da informação, algo que foi encontrado em estudos anteriores (como em Corrêa e Augusto (2011)). / The present study investigates the behavior of children with Specific Language Impairment (SLI) when producing the complex syntactic structure of Long Distance WH- Question and compares it to the production of the same structure by Typically Developing children (TD) at the age of language acquisition in Brazilian Portuguese. Data was taken from 2 groups of children (TD and SLI) aged from 5 to 11 years old. The elicitation method, implemented by Thornton (1990), was used for the experiment. 16 WH-questions were elicited from each child, i.e., 8 with object extraction (4 WH-bare and 4 WHICH+N) and 8 with subject extraction (4 WH-bare and 4 WHICH+N). Data obtained from the 2 groups showed that TD children as well as the SLI group master the complex WH-questions at the age of 5, however, SLI children produced this syntactic structure less frequently (36,65%) than the TD group (89,70%). SLI children certainly faced difficulties in producing it. However, this group of children produced WH-questions with object extraction (55,55%) as frequently as the production of the WH-questions with subject extraction (44,44%). Data analysis suggests that SLI children are able to deal with both syntactic structures (subject and object WH-questions) the same way. SLI children did not produce WH- in situ (a syntactic structure licensed in Brazilian Portuguese).
