The main purpose of this study was to investigate the effects of form-focused instruction (FFI) on prosody with or without self-assessment on the prosodic and global aspects of L2 speech by Japanese EFL learners using a pre-post design. In addition, native English speaking (NS) and non-native English speaking (NNS) raters with high levels of English proficiency were compared to examine the influence of raters’ L1 backgrounds on their comprehensibility ratings. Sixty-one Japanese university students from four intact English presentation classes participated in the study. The comparison group (n = 16) practiced making one-minute speeches in class (45 minutes x 8 times) without explicit instruction on prosody, while the two experimental groups (n = 17 for the FFI-only group; n = 28 for the FFI + SA group) received FFI on word stress, rhythm, and intonation, practiced the target prosodic features in communicative contexts, and received metalinguistic feedback from the instructor. In total, the experimental groups received six-hours of instruction in class, which was comparable to the comparison group. Additionally, the experimental groups completed homework three times; only the FFI + SA group recorded their reading performance and self-assessed it in terms of word stress, rhythm, and intonation. Three oral tasks were employed to elicit the participants’ speech before and after the treatment: reading aloud, one-minute speech, and picture description. The speech samples were rated for comprehensibility by NS and NNS raters and were also analyzed with four prosodic measurements: word stress, rhythm, pitch contour, and pitch range. Instructional effects on prosody were observed clearly. The FFI-only group improved their controlled production of rhythm and pitch contour, while the FFI + SA group significantly improved all of the prosodic features except pitch range. Moreover, the instructional gains for the FFI + SA group were not limited to the controlled task but transferred to the less-controlled tasks. The results showed differential instructional effects on the four prosodic aspects. The FFI in this study did not help the participants widen their pitch range. The FFI on prosody, which was focused on the cross-linguistic differences between Japanese and English, tended to be more effective in terms of improving rhythm and pitch contour, which were categorized as rule-based, than an item-based feature, word stress. The study offered mixed results regarding instructional effects on comprehensibility. The FFI-only group did not significantly improve comprehensibility despite their significant prosodic improvements on the reading aloud task. Their significant comprehensibility growth on the picture description task was not because of the development of prosody, but of other linguistic variables that influence comprehensibility such as speech rate. The FFI + SA group made significant gains for comprehensibility on the three tasks, but the effect sizes were small. This finding indicated that the effects of FFI with self-assessment on comprehensibility were limited due to the multi-faceted nature of comprehensibility. The data elicited from the post-activity questionnaires and students’ interviews revealed that not all the participants in the FFI + SA group reacted positively to the self-assessment practice. Individual differences such as previous learning experience and self-efficacy appeared to influence the learners’ perceptions of the self-assessment practice and possibly their instructional gains. The two groups of raters, L1 English raters (n = 6) and L2 English raters with advanced or native-like English proficiency (n = 6) did not differ in terms of consistency and severity. These findings indicated that NNS raters with high English proficiency could function as reliably as NS raters; however, the qualitative data revealed that the NS raters tended to be more sensitive to pronunciation, especially at the segmental level, across the three tasks compared to the NNS raters. This study provides evidence that FFI, especially when it is reinforced by self-assessment, has pedagogical value; it can improve learners’ production of English prosody in controlled and less-controlled speech, and these gains can in turn contribute to enhanced L2 comprehensibility. / Teaching & Learning

The purpose of this study was to examine the following prosodic elements: speech rate, turn-taking latency, number of interruptions, and utterance duration across two groups' neurotypical and autistic young adults. Furthermore, the end goal of this study is to help provide a baseline and clinical application of prosodic differences between autistic and neurotypical adults. Speech samples were collected from 11 neurotypical and 11 autistic young adults from the ages of 18-26. Speech samples were recorded responses from a 10-minute interview between two research assistants and the autistic or neurotypical individual. Using Praat software, speech samples were analyzed and used to calculate speech rate, utterance duration, turn-taking latency, and the number of interruptions for each subject. Across the four prosodic elements, there were significant differences between the autistic and neurotypical groups. The neurotypical group exhibited significantly higher speech and interruption rates when compared to the autistic group. Whereas, the autistic group displayed longer turn-taking latency periods and longer utterance durations. Across all conditions, there were no significant difference between biological sex or effect of familiarity within the autistic and neurotypical groups. Results of this study provide clinicians and researchers a baseline of prosodic differences found between autistic and neurotypical individuals. Future research is needed to better understand how these findings might improve the assessment and treatment of autistic individuals.

Organized as a set of three manuscripts, this research draws attention to the academic learning experiences for adolescents with particular attention to adolescents with limited reading proficiency and the use of single case design research as a viable option for discovering solutions to a persisting research-to-practice gap in education. Data analyses included a systematic literature review with findings synthesized into themes using qualitative methods, a multiple probe single case design, a non-parametric statistical analysis, and effect size calculations. The first article is a systematic literature review on the relationship between oral reading fluency and reading comprehension for adolescent with limited reading proficiency (ALRP) in grades 6-12. The results of 22 studies were synthesized into five themes and results suggest that knowledge of an adolescent's ORF provides helpful information about his or her reading profile, but is not sufficient to evaluate instructional needs nor measure progress. The article concludes with a discussion on the envelopment of ORF within the Simple View of Reading specifically for adolescent readers as well as implications for practitioners, researchers, policymakers, and assessment developers. The second article presents the findings from a study on the influence of a word level intervention on multiple reading component skills. Six students in two different intervention classes in Virginia participated. The primary analysis was based on a single case design, specifically a multiple probe across participants and settings design. Visual analyses of baseline and intervention phase data indicated a functional relationship between the word level intervention and multiple reading component skills. Statistical analysis (Tau-U) supported this finding with aggregated small effect sizes (0.14 to 0.54) for word identification, accuracy, and automaticity, and one moderate effect size (.70) for prosody. Secondary analysis showed a significant effect for improved strategy knowledge and skill with a 0.90 effect size, but no statistically significant group effects for silent reading fluency and sentence comprehension. The third manuscript is a broad overview of adolescent literacy instructional recommendations and presents a vision for how all teachers contribute to the development of strategic learners when they support content learning through literacy-rich classroom environments. / Doctor of Philosophy / This research draws attention to the academic learning experiences for adolescents, with particular attention to adolescents with limited reading proficiency.

Se distinguant des expressions émotionnelles qui sont innées et déclenchées par un contrôle involontaire du locuteur au sein d'une communication face-à-face, les affects sociaux émergent plutôt de manière volontaire et intentionnelle, et sont largement véhiculés par la prosodie audio-visuelle. Ils mettent en circulation, entre les interactants, des informations sur la dynamique du dialogue, la situation d'énonciation et leur relation sociale. Ces spécificités culturelles et linguistiques de la prosodie socio-affective dans la communication orale constituent une difficulté, même un risque de malentendu, pour les apprenants en langue étrangère (LE) et en langue seconde (L2). La présente thèse se consacre à des études intra- et interculturelles sur la perception de la prosodie de 19 affects sociaux en chinois mandarin et en français, ainsi que sur leurs représentations cognitives. Son but applicatif vise l'apprentissage de la prosodie des affects sociaux en chinois mandarin et en français LE ou L2. Le premier travail de la thèse consiste en la construction d'un large corpus audio-visuel des affects sociaux chinois. 152 énoncés variés dans leur longueur, leur morpho-syntaxe et leur représentation tonale sont respectivement produits dans les 19 affects sociaux. Sur la base de ce corpus, sont examinées l'identification et les confusions perceptives de ces affects sociaux chinois par des natifs, des français et des vietnamiens (comme groupe de référence), ainsi que l'effet du ton lexical sur l'identification auditive des sujets non natifs. Les résultats montrent que la majorité des affects sociaux chinois est perçue de manière similaire par les sujets natifs et les sujets non natifs, cependant certains décalages perceptifs sont également observés. Les tons chinois engendrent des problèmes perceptifs des affects sociaux autant pour les vietnamiens (d'une langue tonale) que pour les français (d'une langue non tonale). En parallèle, une analyse acoustique permet de mettre en évidence les caractéristiques principales de la prosodie socio-affective en chinois et d'étayer les résultats perceptifs. Ensuite, une étude sur les distances conceptuelles d'une part, et psycho-acoustiques d'autre part, entre les affects sociaux est menée auprès de sujets chinois et de sujets français. Les résultats montrent que la plupart des connaissances sur les affects sociaux sont partagées par les sujets, quels que soient leur langue maternelle, leur genre ou la manière de présenter les affects sociaux (concepts ou entrées acoustiques). Enfin, le dernier chapitre de la thèse est consacré à une étude contrastive sur la perception multimodale des affects sociaux en chinois et en français LE ou L2. Il est constaté que la reconnaissance des affects sociaux est étroitement liée aux expressions elles-mêmes et à la modalité de présentation de ces expressions. Le degré d'acquisition de la langue cible du sujet (débutant ou intermédiaire) n'a pas d'impact significatif à la reconnaissance, dans le cadre restreint des niveaux étudiés. / In human face-to-face interaction, social affects should be distinguished from emotional expressions, triggered by innate and involuntary controls of the speaker, by their nature of voluntary controls expressed within the audiovisual prosody and by their important role in the realization of speech acts. They also put into circulation between the interlocutors the social context and social relationship information. The prosody is a main vector of social affects and its cross-language variability is a challenge for language description as well as for foreign language teaching. Thus, cultural and linguistic specificities of the socio-affective prosody in oral communication could be a difficulty, even a risk of misunderstanding, for foreign language and second language learners. This thesis is dedicated to intra- and intercultural studies on perception of the prosody of 19 social affects in Mandarin Chinese and in French, on their cognitive representations, as well as on Chinese and French socio-affective prosody learning for foreign and second language learners. The first task of this thesis concerns the construction of a large audio-visual corpus of Chinese social affects. 152 sentences with the variation of length, tone location and syntactic structures of utterances, have been incorporated with 19 social affects. This corpus is served to examine the identification and perceptual confusion of these Chinese social affects by native and non-native listeners, as well as the tonal effect on non-native subjects' identification. Experimental results reveal that the majority of social affects are similarly perceived by native and non-native subjects, otherwise, some differences are also observed. Lexical tones lead to certain perceptual problems also for Vietnamese listeners (of a tonal language) and for French listeners (of a non-tonal language). In parallel, an acoustic analysis investigates the production side of prosodic socio-affects in Mandarin Chinese, and allows highlighting the more prominent patterns of acoustical variations as well as supporting the perceptual resultants obtained on the same expressions. Then, a study on conceptual and psycho-acoustic distances between social affects is carried out with Chinese and French subjects. The main results indicate that all subjects share to a very large extent the knowledge about these 19 social affects, regardless of their mother language, gender or how to present social affects (concept or acoustic realization). Finally, the last chapter of thesis is dedicated to the differences in the perception of 11 Chinese social affects expressed in different modalities (audio only, video only and audio-visual) for French learners and native subjects, as well as in the perception of the same French socio-affects for Chinese learners and native subjects. According to the results, the identification of affective expressions depends more on their affective values and on their presentation modality. Subject's learning level (beginner or intermediate) does not have a significant effect on their identification.

Cette thèse de doctorat s’inscrit principalement, mais non entièrement, dans le domaine de la phonologie générale et romane. Elle a pour objet d’étude plusieurs phénomènes de sandhi attestés dans quelques variétés de gallo-roman : français, occitan, wallon, franco-provençal. Comme une grande partie des phénomènes phonologiques postlexicaux étudiés sont panromans, la thèse ne les analyse pas comme des processus isolés, mais à travers leur variation diatopique et diachronique, c’est-à-dire comme des manifestations concrètes de tendances communes aux langues romanes, tout en essayant d’expliquer leur motivation par des principes phonologiques universels, ainsi que par les méthodes de l’analyse contrastive.Dans cette thèse on pourrait délimiter trois grandes parties thématiques. La première a une portée théorique et englobe les chapitres I et II où sont présentées et analysées des données d’une soixantaine de langues parlées dans le monde entier. Dans cette partie je passe en revue les diverses acceptions controversées du terme de sandhi en vue d’en proposer ma propre définition grâce au formalisme de la phonologie prosodique. La deuxième partie a une portée phonologique et englobe les chapitres III, IV et V où sont étudiés trois phénomènes de sandhi de l’espace gallo-roman, à savoir la liaison, le redoublement phonosyntaxique et les alternances vocaliques avec zéro en syllabe initiale. La dernière partie thématique est représentée par le chapitre VI qui a une portée sociolinguistique. Les trois phénomènes de sandhi en question y sont comparés et analysés à la lumière des facteurs pour leur variation, parmi lesquels la tradition graphique occupe une place privilégiée. / This doctoral dissertation thesis pertains primarily, but not solely, to the field of general phonology and Romance phonology. The object of investigation are a number of sandhi phenomena attested in several Gallo-Romance varieties: French, Occitan, Walloon, and Franco-Provençal. The larger part of the postlexical phonological phenomena under investigation is pan-Romance and therefore they are not analyzed as isolated processes. They are interpreted with respect to their diatopic and diachronic variation, in other words, as specific manifestations of tendencies common to all Romance languages. The explanation for such common tendencies is sought in universal phonological principles and by the established methods of comparative analysis.Three large thematic parts can be distinguished in the thesis. The first part comprises the first two chapters and is theoretical in nature. Data from over 60 languages spoken in various parts of the world are presented and analyzed in this part. It also contains a critical review of the highly controversial existing usages of the term “sandhi” and attempts to offer a new original definition in the framework of prosodic phonology. The second part is devoted to concrete phonological analyses and comprises chapters III, IV and V. The sandhi processes in the Gallo-Romance language space are studied in details: liaison, phonosyntactic doubling and elision of vowels in initial syllables. The last thematic part, presented in chapter VI, is devoted to sociolinguistic observations. The three phenomena mentioned above are compared and analyzed with regard to the factors governing their variation, among them the orthographic tradition.
