La Langue française Parlée Complétée est un système peu connu du grand public. Adapté du Cued Speech en 1977, il a pour ambition d’aider les sourds francophones à percevoir un message oral en complétant les informations fournies par la lecture labiale à l’aide d’un geste manuel. Si, depuis sa création, la LPC a fait l’objet de nombreuses recherches scientifiques, peu de chercheurs ont, jusqu’à présent, étudié les processus mis en jeu dans la perception de la parole codée. Or, par la présence conjointe d’indices visuels (liés aux lèvres et à la main) et d’indices auditifs (via les prothèses auditives ou l’implant cochléaire), l’étude de la LPC offre un cadre idéal pour les recherches sur l’intégration multimodale dans le traitement de la parole. En effet, on sait aujourd’hui que sourds comme normo-entendants mettent à contribution l’ouïe et la vue pour percevoir la parole, un phénomène appelé intégration audio-visuelle (AV).<p><p>Dans le cadre de cette thèse nous avons cherché à objectiver et caractériser l’intégration labio-manuelle dans la perception de la parole codée. Le poids accordé par le système perceptif aux informations manuelles, d’une part, et aux informations labiales, d’autre part, dépend-il de la qualité de chacune d’entre elles ?Varie-t-il en fonction du statut auditif ?Quand l’information auditive est disponible, comment le traitement de l’information manuelle est-il incorporé au traitement audio-visuel ?Pour tenter de répondre à cette série de questions, cinq paradigmes expérimentaux ont été créés et administrés à des adultes sourds et normo-entendants décodant la LPC. <p><p>Les trois premières études étaient focalisées sur la perception de la parole codée sans informations auditives. Dans l’étude n° 1, le but était d’objectiver l’intégration labio-manuelle ;l’impact de la qualité des informations labiales et du statut auditif sur cette intégration a également été investigué. L’objectif de l’étude n° 2 était d’examiner l’impact conjoint de la qualité des informations manuelles et labiales ;nous avons également comparé des décodeurs normo-entendants à des décodeurs sourds. Enfin, dans l’étude n° 3, nous avons examiné, chez des décodeurs normo-entendants et sourds, l’effet de l’incongruence entre les informations labiales et manuelles sur la perception de mots. <p><p>Les deux dernières études étaient focalisées sur la perception de la parole codée avec du son. L’objectif de l’étude n°4 était de comparer l’impact de la LPC sur l’intégration AV entre les sourds et les normo-entendants. Enfin, dans l’étude n°5, nous avons comparé l’impact de la LPC chez des décodeurs sourds présentant une récupération auditive faible ou forte. <p><p>Nos résultats ont permis de confirmer le véritable ancrage du code LPC sur la parole et de montrer que le poids de chaque information au sein du processus d’intégration est dépendant notamment de la qualité du stimulus manuel, de la qualité du stimulus labial et du niveau de performance auditive.<p> / Doctorat en Sciences Psychologiques et de l'éducation / info:eu-repo/semantics/nonPublished

[pt] Nos últimos anos, países democráticos presenciaram a participação de fake news em seus processos deliberativos. A forma como ela ocorreu variou de acordo com as especificidades da estrutura comunicacional de cada nação. A expressiva presença de fake news em eleições recentes suscitou a preocupação sobre a possibilidade de esses materiais estarem interferindo em processos deliberativos, causando contextos de desinformação, enganando e manipulando eleitores e, consequentemente, afetando seus resultados. Esta dissertação analisa a participação das fake news na eleição presidencial de 2016 nos Estados Unidos, bem como nas eleições presidenciais de 2018 e municipais de 2020 no Brasil. Busca compreender de que forma esses conteúdos foram utilizados em cada um dos contextos acima, quais os mecanismos de disseminação usados, as abordagens adotadas, os principais temas levantados, a abrangência da sua difusão, as possíveis influências que podem ter exercido e a sua relevância em cada um desses contextos. / [en] In recent years, democratic countries have witnessed the participation of fake news in their deliberative processes.

The significant presence of fake news in recent elections has raised concerns about the possibility that these materials are interfering with deliberative processes, causing contexts of disinformation, deception and manipulation of voters, consequently affecting their results. This dissertation analyzes the participation of fake news in the 2016 presidential election in the United States, as well as in the 2018 presidential and 2020 municipal elections in Brazil. It seeks to understand how these contents were used in each of the above contexts, which dissemination mechanisms were used, the approaches adopted, the main issues raised, the extension of their diffusion, the possible influences they may have had and their relevance in each one of those contexts.

A description of the developmental characteristics of adolescents and the effect of deafness, on the cognitive emotional and social development of the Deaf adolescent boy is given. At a stage, when the parents influence is crucial in any child's upbringing, the Deaf child, mainly because of his/her need for special educational services is placed in a school hostel at an early age. The aim of the investigation was two-fold: • Firstly, from thl! literature study, to analyze and describe the educational distress of the Deaf adolescent boy residing in the school hostel. Secondly, to conduct an empirical survey consisting of structured questionnaires in order to ascertain the kind of support rendered to the Deaf adolescent boy in the hostel. From the literature study and the empirical survey a training/educational programme was designed to promote the educational skills of hostel parents at schools for Deaf adolescent boys. / Inclusive Education / M.Ed.(Orthopedagogics)

De nombreuses études longitudinales ont montré un lien causal entre habiletés phonologiques précoces et plus tard le développement de la lecture et de l’écriture chez l’enfant entendant (Bryant, MacLean, Bradley & Crossland, 1990). Pour apporter une contribution aux connaissances concernant ce lien chez les enfants sourds, nous avons réalisé une étude longitudinale qui s’échelonne de la troisième maternelle à la seconde primaire. Les performances d’enfants sourds sévères et profonds prélinguaux exposés (précocement vs tardivement) ou non au Langage Parlé Complété (« LPC », code manuel destiné à lever l’ambiguïté de la lecture labiale seule) sont comparées à celles d’enfants entendants de même âge chronologique. Diverses épreuves phonologiques, de lecture et d’écriture ont été proposées. Les résultats ont montré que les habiletés phonologiques précoces prédisaient le niveau de reconnaissance de mots écrits en première primaire chez les enfants sourds comme chez les enfants entendants. Cependant, un effet plus important de l’apprentissage de la lecture est observé sur le niveau d’habiletés phonologiques, de lecture et d’écriture lors des deux premières primaires chez les enfants sourds. De plus, les performances des enfants sourds exposés précocement au LPC ne diffèrent pas de celles des enfants entendants et sont plus élevées que celles des autres enfants sourds, en particulier en première et seconde primaire. L’exposition précoce au LPC permettrait donc le développement de représentations phonologiques précises et par conséquent l’utilisation d’un décodage phonologique efficace en lecture et en écriture au début de l’apprentissage de la lecture. / Longitudinal studies have shown a causal connection between early phonological skills and later literacy development in hearing children (Bryant, MacLean, Bradley & Crossland, 1990). The aim of our study is to investigate whether early phonological skills predict later literacy performance in deaf children either exposed (early versus late) or not exposed to Cued Speech (“CS”, a manual system delivering phonetically augmented speechreading through the visual modality). Different phonological and literacy tasks were administered from kindergarten to seconde grade. The results show that the early phonological skills in kindergarten predict written word recognition in first grade in the deaf as well as in the hearing groups. However, an effect of learning to read seems to be more important on the level of phonological and literacy skills during the first and seconde grade in deaf children. In addition, the performances of early CS users do not differ from those of hearing children and are higher than those of the other deaf children, especially in first and second grade. Early exposure to Cued Speech may permit the development of accurate phonological representations and, consequently, the use of accurate phonological decoding to recognize written words and to spell at an early stage in learning to read. / Doctorat en sciences psychologiques / info:eu-repo/semantics/nonPublished
