Child Language Brokering is a very common phenomenon for Latinx/a/o children of immigrants, who usually begin language serving as translators and interpreters at a young age and carry these roles into adulthood.

This dissertation investigates the child language acquisition of Kosraean (ISO 639-3 kos) and English (ISO 639-3 eng) on the island of Kosrae of the Federated States of Micronesia, with the aim of assessing the current vitality status of Kosraean and its strength compared to English. The concerns raised by the community regarding child proficiency…

Prior research has extensively explored audiovisual speech perception and literacy skills in various linguistic contexts. Studies have shown that children's ability to integrate auditory and visual speech cues plays a crucial role in language acquisition and development (Erdener & Burnham, 2013; Lalonde & Werner, 2021). Furthermore,…

This dissertation draws on both qualitative and quantitative approaches to investigate the linguistic practices of teachers and children who are learning Mandarin Chinese as a Heritage Language (CHL) in two dual immersion preschools in California. CHL children have been interpreted as novice members in local speech communities who actively explore…

Much research on requests has been carried out among L1 Chinese adults, L1 Chinese children, L1 children, L2 adults, and L2 children, but no studies to date have simultaneously examined Chinese children's requests in Chinese (L1) and English (L2). The aim of this study is to investigate how Taiwanese elementary school children vary requests…

This study introduces a typological model of the "conceptual language-specific approach" to the L2 research on the acquisition of tense-aspect. The model is based on the typological notion of prominence, classifying languages into tense-prominent and aspect-prominent (Bhat 1999) and the L1 research proposal that language-specific…
