A aquisição e o desempenho de linguagem humana é um processo pelo qual todas as pessoas passam. No entanto, esse processo não é completamente entendido, o que gera amplo espaço para pesquisa nessa área. Além disso, mesmo após o processo de aquisição da linguagem pela criança estar completo, ainda não há garantia de domínio da língua em suas diferentes modalidades, especialmente de leitura e escrita. Recentemente, em 2016, divulgou-se que 49,3% dos estudantes brasileiros não possuem proficiência de compreensão de leitura plena em português. Isso é particularmente importante ao considerarmos a quantidade de textos disponíveis, mas não acessíveis a pessoas com diferentes tipos de problemas de proficiência na língua. Sob o ponto de vista computacional, há estudos que visam modelar os processos de aquisição da linguagem e medir o nível do falante, leitor ou redator. Em vista disso, neste trabalho propomos uma abordagem computacional independente de idioma para modelar o nível de desenvolvimento linguístico de diferentes tipos de usuários da língua, de crianças e adultos, sendo a nossa proposta fortemente baseada em características linguísticas. Essas características são dependentes de corpora orais transcritos, no segmento de crianças, e de corpora escritos, no segmento de adultos. Para alcançar esse modelo abrangente, são considerados como objetivos a identificação de atributos e valores que diferenciam os níveis de desenvolvimento da linguagem do indivíduo, assim como o desenvolvimento de um modelo capaz de indicá-los. Para a identificação dos atributos, utilizamos métodos baseados em estatística, como o teste de hipóteses e divergência de distribuição. A fim de comprovar a abrangência da abordagem, realizamos experimentos com os corpora que espelham diferentes etapas do desenvolvimento da linguagem humana: (1) etapa de aquisição da linguagem oral de pela criança e (2) etapa pós aquisição, através da percepção de complexidade da linguagem escrita. Como resultados, obtivemos um grande conjunto anotado de dados sobre aquisição e desempenho de linguagem que podem contribuir para outros estudos. Assim como um perfil de atributos para os vários níveis de desenvolvimento. Também destacamos como resultados, os modelos computacionais que identificam textos quanto ao nível de desenvolvimento de linguagem. Em especial, o são resultados do trabalho o modelo de identificação de palavras complexas, que ultrapassou o estado da arte para o corpus estudado, e o modelo de identificação de idade de crianças que ultrapassou os baselines utilizados, incluindo uma medida clássica de desenvolvimento linguístico. / Language acquisition and language performance is a process by which all the people experience. However, this process is not completely understood, which creates room for research in this area. Moreover, even after the acquisition process by a child is completed, there is still no guarantee of language proficiency in different modalities, specially reading and writing. Recently, in 2016, OECD/PIAAC released that 49,3% of Brazilian students do not have written and read proficiency in Portuguese. This is more important when we take into account the large number of available text, but they are not accessible by people with different types of language proficiency issues. In computational point of view, there are some studies which aim to model the language acquisition process and measure the speaker level. For that, we propose an computational approach independent of language to model language development level of different types of language users, children and adults. In that sense our proposal is highly based on linguistics features. Those features dependents of transcript oral corpora from children and adults. To achieve this model, we considered aim to identify attributes and values able to differentiate between leves of development by an individual, as well the desenvolvimento of a model able to indicate them. The attribute identification are based on statistical methods such as hypothesis testing and divergence distribution. Aiming to validate our approach, we performed experiments with the corpora that reflect at different stages of development of human language: (1) oral language acquisition by a child and (2) post-acquisition stage, through the perception of difficulty of written language. With this work, we obtained a large corpus of annotated language acquisition data that can contribute to the acquisition of other studies. We also build an attribute profile of the development levels. From all of our results we highlight the computer models that identify texts and language development level. In particular, the complex word identification model that exceeded the state of the art for the studied corpus, and the children age identifier model, who exceeded the baselines, including a classic measure of language development.

Complex Word Identification (CWI) is a task of identifying complex words in text data and it is often viewed as a subtask of Automatic Text Simplification (ATS) where the main task is making a complex text simpler. The ways in which a text should be simplified depend on the target readers such as second language learners or people with reading disabilities. In this thesis, we focus on Complex Word Identification for Swedish. First, in addition to exploring existing resources, we collect a new dataset for Swedish CWI. We continue by building several classifiers of Swedish simple and complex words. We then use the findings to analyze the characteristics of lexical complexity in Swedish and English. Our method for collecting training data based on second language learning material has shown positive evaluation scores and resulted in a new dataset for Swedish CWI. Additionally, the built complex word classifiers have an accuracy at least as good as similar systems for English. Finally, the analysis of the selected features confirms the findings of previous studies and reveals some interesting characteristics of lexical complexity.

L’objectif de ce travail de thèse était d’étudier l’implication des systèmes visuels magnocellulaire et parvocellulaire dans le traitement de langage écrit, spécialement dans l’identification des mots. Quatre études expérimentales ont été réalisées afin de documenter le rôle respectif de ces deux systèmes pour différentes composantes de la structure du mot écrit, la lettre (Etude 1), la longueur du mot (Etude 2) et l’enveloppe du mot (Etude 3), ainsi que le voisinage orthographique (Etude 4). La dissociation des deux sous-systèmes visuels se fondait sur leurs caractéristiques fonctionnelles spécifiques : sensibilité aux fréquences spatiales basses et au contraste de luminance pour le système magnocellulaire ; sensibilité aux fréquences spatiales moyennes et élevées et au contraste chromatique pour le système parvocellulaire. Les participants étaient des adultes jeunes normolecteurs et des enfants de 10-11 ans, lecteurs novices, afin d’envisager l’implication de chaque système visuel à deux étapes de leur développement : maturité chez l’adulte jeune ; en cours de maturation chez l’enfant. Les résultats ont confirmé le rôle prépondérant des traitements parvocellulaires, ce qui corroborait le privilège accordé au traitement des lettres et traits des lettres dans la reconnaissance visuelle des mots. Le traitement de la longueur du mot s’est en revanche révélé être une dimension sélectivement magnocellulaire. L’ensemble des résultats est discuté dans le cadre de l’approche coarse-to-fine. / The main objective was to study the implication of the magnocellular and the parvocellular visual systems in written language processing, specifically in word identification. Four studies were carried out to document the respective roles of these two systems, for different components of the written word structure, the letter (Study 1), the word length (Study 2), the word shape (Study 3) and the orthographic neighborhood (Study 4). The dissociation of the two visual systems was based on their specific functional characteristics: sensitivity to low spatial frequencies and luminance contrast for the magnocellular system; and sensitivity to medium and high spatial frequencies and chromatic contrast for the parvocellular system. The participants were young adult normal readers and 10-11 years-old children, novice readers, in order to consider the involvement of each visual system at two stages of their development: mature in young adults while still maturing in the children. The results confirmed the prominent role of parvocellular processing, which was consistent with the privilege accorded to the processing of letters and letters features in visual word recognition. On the other hand, word length processing has been shown to be a selectively magnocellular dimension. All results are discussed in the framework of the coarse-to-fine approach.

L’objectif de ce travail est double. Il s’agit premièrement de participer au développement d’un logiciel d’évaluation des processus cognitifs engagés lors de l’identification des mots écrits. Ce dispositif informatisé (Tinfolec) évalue les processus d’identification des mots écrits et les traitements phonologiques et visuo-orthographiques sous-jacents. Il a été mis au point au cours de plusieurs pré-expérimentations. Deuxièmement, l’efficacité d’un entraînement informatisé grapho-syllabique a été testée auprès d’enfants faibles lecteurs débutants. En effet, partant du double constat que a) la syllabe est une unité intermédiaire de traitement au début de la lecture en français et b) l’entraînement informatisé aux correspondances grapho-phonologiques améliore l’identification des mots écrits, nous nous attendions à ce qu’un entraînement grapho-syllabique aide les plus faibles lecteurs à améliorer leurs performances dans ce domaine. Une procédure classique en 3 phrases, pré-test/entraînement/post-tests et une comparaison de deux groupes d’enfants, expérimental et contrôle, a été utilisée. Différents post-tests différés ont permis de tester le maintien des effets d’entraînement. Les résultats vont en faveur de l’hypothèse selon laquelle la syllabe est effectivement une unité de traitement privilégiée en français au début de l’apprentissage de la lecture. / The aim of this work was twofold. The first one was to contribute to the development of a software evaluating the cognitive processes involved in written words identification by the means of several pre-experimentations. This device (Tinfolec) evaluates written word identification and its underlying phonological and visual-orthographic processing. Secondly, we tested the effectiveness of a computerized grapho-syllabic training in French beginning poor readers. Based on the two facts that a) the syllable is an intermediate treatment unit in beginning reading in French and b) computerized training of grapho-phonological correspondences improves word identification, we expected that trained poor readers improve in reading. The classical 3-periods-procedure including pre-test/training/post-tests and a comparison of two groups of children, experimental and control, were used. Different post-tests permitted to test the maintenance of the training effects. The results are in favor of the hypothesis that the syllable indeed is an intermediate treatment unit in the French reading process.

Thèse de doctorat présenté en vue de l'obtention du doctorat en psychologie - recherche intervention, option neuropsychologie clinique (Ph.D) / Le trouble développemental du langage (TDL) est souvent associé à des difficultés de lecture, tant sur le plan de la compréhension de lecture que de l’identification des mots écrits, mais les habiletés de lecture varient d’un enfant à l’autre chez cette population. Il est important de s’intéresser aux facteurs de risque qui engendrent des difficultés de lecture chez les enfants ayant un TDL afin de mieux cibler ceux ayant besoin de soutien dans ce domaine et d’optimiser les méthodes d’intervention qui leur sont offertes. Alors que certains facteurs de risque sont bien connus, comme le degré et l’étendue de l’atteinte langagière orale, d’autres demeurent peu étudiés, comme une atteinte des fonctions exécutives (FE). Pourtant, le lien entre FE et lecture est bien établi et les enfants ayant un TDL sont nombreux à vivre des difficultés en FE. Les objectifs principaux de cette thèse, composée de deux articles, étaient d’examiner les profils de lecteurs et d’étudier les liens entre FE et compréhension de lecture chez des enfants francophones du primaire ayant un TDL. Pour y arriver, le premier article poursuit la validation des sous-tests « Lecture de mots et de pseudomots » et « Dictée de mots et de pseudomots » du Test d’évaluation du langage écrit québécois (TELEQ). Ces sous-tests ont été développés et prévalidés pour répondre au manque d’outils d’évaluation du langage écrit détenant de bonnes propriétés psychométriques et adaptés aux enfants franco-québécois du primaire. Deux objectifs étaient poursuivis : 1) consolider la validation de ces sous-tests auprès d’enfants ayant une dyslexie-dysorthographie 2) offrir des normes préliminaires pour ces sous-tests. Les participants étaient répartis dans le groupe contrôle (n = 171) et clinique (n = 49). Les courbes de caractéristique de performance ont permis de déterminer la sensibilité (87,76 %) et la spécificité (97,66 %) de l’utilisation des six mesures obtenues à ces sous-tests. Ces sous-tests s’avèrent pertinents pour l’évaluation des difficultés de lecture et d’écriture ainsi que pour le diagnostic et le dépistage de la dyslexie-dysorthographie dans les milieux cliniques et de recherche québécois. Dans le deuxième article, le TELEQ a été utilisé pour décrire les profils de lecteurs d’enfants ayant un TDL et examiner le lien entre les FE et la compréhension de lecture. Le TELEQ a été administré à 81 enfants de la 4e à la 6e année primaire (contrôle : n = 66, TDL : n = 15). Une majorité d’enfants ayant un TDL présentait des difficultés en compréhension de lecture et en identification des mots écrits (profil faible lecteur, 8/13). Une évaluation globale des FE a montré que plusieurs des enfants ayant un TDL présentaient une atteinte importante des FE. Parmi les enfants ayant un TDL au profil faible lecteur, la majorité présentait à la fois une atteinte des processus cognitifs ne nécessitant pas les inférences et une atteinte des processus cognitifs nécessitant les inférences en compréhension de lecture, mais deux cas d’exception étaient observés. Chez eux, certains facteurs protecteurs étaient relevés, tels que l’absence d’une atteinte sur la sphère réceptive du langage (2/2) ou en FE (1/2). Les FE étaient fortement reliées aux habiletés de compréhension de lecture dans les deux groupes (contrôle : r = 0,38, TDL : r = 0,72). Dans le groupe TDL, les FE étaient reliées aux deux types de processus cognitifs en compréhension de lecture (nécessitant ou non les inférences), alors que dans le groupe contrôle, les FE étaient reliées seulement aux processus nécessitant les inférences. Les FE n’apportaient pas de valeur prédictive unique à la compréhension de lecture au-delà des variables du modèle simple de la lecture (compréhension langagière orale et identification de mots écrits), deux composantes déjà connues comme impliquées dans la compréhension de lecture. Ainsi, l’effet des FE sur la compréhension de lecture semble être majoritairement indirect, via son effet sur les deux composantes du modèle simple de la lecture. Les implications théoriques et cliniques des résultats de cette thèse sont discutées à la lumière des connaissances actuelles et différentes pistes de recherches futures sont évoquées. / Developmental language disorder (DLD) is often associated with reading difficulties in both reading comprehension and written word identification, but reading skills vary from child to child in this population. It is important to address the risk factors that lead to reading difficulties in children with DLD to better target children who need support in this area and to optimize the intervention methods offered to them. While some risk factors are well known, such as the degree and extent of oral language impairment, others remain poorly studied, such as executive function (EF) impairment. However, the link between EF and reading is well established and many children with DLD experience difficulties in EF. The main objectives of this thesis, consisting of two articles, were to examine the profiles of readers and to study the links between EF and reading comprehension in French-speaking primary school children with TDL. To this end, the first paper continues the validation of the subtests "Lecture de mots et de pseudomots" and "Dictée de mots et de pseudomots " of the Test d'évaluation du langage écrit québécois (TELEQ). These subtests were developed and pre-validated in response to the lack of written language assessment tool with good psychometric properties and adapted to Quebec francophone children in elementary school. Two objectives were pursued: 1) to consolidate the validation of these subtests with children with dyslexia/dysorthographia 2) to provide preliminary norms for these subtests. Participants were divided into control (n = 171) and clinical (n = 49) groups. Performance characteristic curves were used to determine the sensitivity (87.76%) and specificity (97.66%) of using the six measures obtained on these subtests. These subtests have proven to be relevant tools for the assessment of reading and writing difficulties as well as for the diagnosis and screening of dyslexia/dysorthographia in Quebec clinical and research settings. In the second paper, the TELEQ was used to describe the reading profiles of children with DLD and to examine the relationship between EF and reading comprehension. The TELEQ was administered to 81 children in grades 4-6 (control: n = 66, DLD: n = 15). A majority of DLD children had difficulties in reading comprehension and written word identification (poor reader profile; 8/13). A global assessment of EF showed that many of the DLD children had significant impairment in EF. Among DLD children with poor reader profile, the majority showed both impairment of cognitive processes not requiring inference and impairment of processes requiring inference in reading comprehension, but two exceptional cases were observed. In these cases, certain protective factors were noted, such as the absence of impairment in the receptive sphere of language (2/2) or in EF (1/2). EF were strongly related to reading comprehension skills in both groups (control: r = 0.38, DLD: r = 0.72). In the DLD group, EF were related to both types of cognitive processes in reading comprehension (requiring or not inferences), whereas EFs were only related to processes requiring inferences in the control group. EF did not provide unique predictive value for reading comprehension beyond the variables of the simple view of reading (listening comprehension and word identification skills), two components already known to be involved in reading comprehension. Thus, the effect of FE on reading comprehension seems to be mostly indirect, via its effect on the two components of the simple view of reading The theoretical and clinical implications of the results of this thesis are discussed in the light of current knowledge and various avenues for future research are discussed.
