Perceptual representations in Interlanguage Phonology : subcategorial learning in late-learners with a smaller vowel inventory

Barrientos Contreras, Fernanda January 2018 (has links)
In this thesis I explore the phonological nature of newly acquired perceptual representations by highly proficient late-learners of English whose L1 is Spanish, specifically in the case where two different L2 sounds are being initially mapped onto the same L1 category. I claim that these perceptual representations are not phonemic; rather, what these learners acquire are phonetic representations that can be discriminable under certain conditions in a manner similar to that of native speakers, but that are nevertheless identified as tokens of the same L1 category. Since speech perception is a categorisation process where the acoustic input is mapped onto the existing phonemic categories, then late-learners will use their L1 representations when perceiving acoustic input; and will therefore have no need to create new perceptual categories. An alternative hypothesis holds that late-learners can bootstrap new perceptual categories by means of UG access, which allows them to bypass the default categorisation process and notice the difference between their L1 categories and the actual L2 input, so that new perceptual categories can be created. This thesis focuses on the acquisition of the perceptual contrast between the open-mid back unrounded vowel /2/ and the low back unrounded vowel /A/, both of which are mapped onto the same L1 perceptual category /a/. Two experiments were conducted. Subjects were divided in three groups: one of native speakers (NS), a group of highly proficient nonnative speakers of English with Spanish as L1 (NNS-A), and a group of L1 Spanish speakers who were nonproficient in English (NNS-B). The experiments included identification, discrimination and rating tasks along synthesised /A - 2/ vowel continua (7-step and 5-step). The results showed that unlike the NS group, both groups of nonnative speakers categorised the tokens along the /2 - A/ continuum randomly when using L2-like labels; and showing a strong preference towards /a/ when using L1-like labels. Discrimination, on the other hand, differed according to the task: discrimination of adjacent tokens yielded similar results across the three groups, but nonadjacent tokens showed that the NNS-A group is more sensitive than the NNS-B group and less sensitive than the NS group. Finally, prototypicality ratings showed that while NS considered the endpoints of the continuum as good exemplars of the categories /A/ and /2/, both groups of nonnative speakers rated all tokens along the continuum as equally good instances of /a/. From these results I conclude that while late-learners of L2 English do not create new phonemic categories for /A/ and /2/, they are able to perceive a difference that nevertheless does not seem to be enough to create a category split. These findings have implications for a theory of learnability in SLA, since it suggests that latelearners have partial access to UG insofar as input alone leads to learning within the phonetic domain but not to creation of new phonemic categories.

Spatial Mnemonics for L2 Vocabulary Recall. Customized Training for 21st Century Students

Larchen Costuchen, Alexia 31 July 2023 (has links)
Tesis por compendio / [ES] Esta tesis tiene como objetivo promover la colaboración entre profesores de L2, profesionales de las Tecnologías de la Información y estudiantes de L2 que abordan la tecnología del siglo XXI con una mentalidad digital. Específicamente, busca proporcionar soluciones prácticas para la memorización y el compromiso eficientes del vocabulario SL/LE/L2 mediante el uso mnemónico de memoria espacial y entornos inmersivos. Metodológicamente cuenta con la recopilación de datos numéricos analizados estadísticamente y con la exploración subjetiva compartida por los participantes. El texto es un compendio de artículos publicados que destacan diferentes aspectos del contenido de la tesis. El autor tuvo en mente una pregunta común para los estudios cuantitativos: si el enfoque experimental demostraría resultados estadísticamente significativos en comparación con las técnicas de control donde las preguntas abiertas eran la base para las investigaciones cualitativas. Además, se utilizaron encuestas para obtener opiniones en un formato estandarizado. Todos los estudios realizados demostraron la efectividad de la espacialización mnemotécnica en combinación con AR, VR y dentro de un videojuego exploratorio, y reunieron información valiosa de los participantes individuales. Investigaciones complementarias confirmaron la predilección de los estudiantes por cursos personalizados y la necesidad de innovaciones didácticas. / [CA] Aquesta tesi té com a objectiu promoure la col·laboració entre professors de L2, professionals de les Tecnologies de la Informació i estudiants de L2 que aborden la tecnologia del segle XXI en una mentalitat digital.

El text és un compendi d'articles publicats que destaquen diferents aspectes del contingut de la tesi. L'autor va tindre en ment una pregunta comuna per als estudis quantitatius: si l'enfocament experimental demostraria resultats estadísticament significatius en comparació a les tècniques de control on les preguntes obertes eren la base per a les investigacions qualitatives. A més, es van utilitzar enquestes per a obtenir opinions en un format estandarditzat. Tots els estudis realitzats van demostrar l'efectivitat de l'espacialització mnemotècnica en combinació amb AR, VR i dins d'un videojoc exploratori, i van reunir informació valuosa dels participants individuals. Investigacions complementàries van confirmar la predilecció dels estudiants per cursos personalitzats i la necessitat d'innovacions didàctiques. / [EN] This thesis is aimed at promoting collaboration among L2 teachers, IT professionals, L2 students tackling 21st century technology, and the modern digitally minded public. Specifically, it seeks to provide practical solutions for efficient SL/FL/L2 vocabulary memorisation and engagement via the use of visuospatial mnemonics in immersive environments. Methodologically it counts on a collection of numerical data analysed statistically and by exploring a subjective perspective shared by the participants. The manuscript is a compendium of published papers that highlight different aspects of the thesis content. The author kept in mind a common question for quantitative studies which was if the experimental approach would demonstrate statistically significant results in comparison to control techniques while open-ended questions were the base for qualitative inquiries. In addition, surveys were used to obtain opinions in a standardized format. All the studies conducted both demonstrated the effectiveness of mnemonic spatialization in combination with AR, VR and within an explorative videogame, and collected valuable insights from individual participants. Supplementary research confirmed students' predilection for tailor-made courses and the need for didactic innovations. / Larchen Costuchen, A. (2023). Spatial Mnemonics for L2 Vocabulary Recall.

Prácticas internacionales en el extranjero y percepciones de la mejoría lingüística y competencia cultural: Una evaluación del programa “Auxiliares de Conversación”

Erk, Miranda Richelle 09 January 2013 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / Este estudio analiza las percepciones de mejoría en el español y de conocimiento cultural de los participantes en un programa de ayudantes de inglés, Auxiliares de Conversación, mientras trabajaron en escuelas primarias y secundarias en varias regiones de España. Los participantes provenían de varios países anglófonos, entre ellos los Estados Unidos, el Reino Unido, Canadá, Nueva Zelanda, Australia. Varios participantes rellenaron encuestas a través de internet para evaluar su crecimiento lingüístico y cultural durante el programa, experiencia en los centros educativos y alojamiento. Además, plantearon varias sugerencias para el programa para futuros auxiliares y profesores. Seis auxiliares fueron entrevistados sobre los mismos temas en mayor profundidad.
