Infants are born highly sensitive to the natural patterns found in languages. They use their perceptual sensitivity to acquire detailed information about the structure of languages in their environment. To date, most studies of infant perception and early language acquisition have investigated spoken/auditory languages and hearing infants (e.g.…

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…

The present study aimed to catalogue and compare usage patterns of verb-particle constructions (VPCs) in Modern Standard Arabic and English by native and learner writers. Building upon an analysis of a multi-genre monolingual Arabic corpus, use of both Arabic and English VPCs was explored in a bilingual L1 (first language) Arabic L2 (second…

This dissertation investigates language-specific acoustic and aerodynamic phenomena in language contact situations. Whereas most work on second language and bilingual phonology has focused on individual consonants and vowels, this project examines patterns of coarticulation in the two languages of Spanish-English and French-English bilingual…

This dissertation provides a comprehensive analysis of the L2 acquisition of Spanish psych-verbs (e.g. "gustar" "to like") across four different proficiency levels. In particular, psych-verbs constitute a testing ground for the predictions of the Interface Hypothesis (Sorace and Filiaci, 2006; Tsimpli, Sorace, Heycok &…

The present study is concerned with language contact between Creole English and Spanish spoken by bilingual West Indians who live in Panama City, Panama. The goal of this study is to examine the speech patterns of monolinguals of Creole English and Spanish and Spanish-Creole English bilinguals in the local communities of this region, by employing…

This study explores dispute sequences in talk between bilingual couples communicating in Japanese. Specifically I examine naturally occurring face-to-face talk between Japanese wives and their American husbands who communicate primarily in Japanese at home. Conversation analysis (CA) is employed to document occasions where the talk between these…

English and a small set of other languages have a wealth of available linguistic knowledge resources and annotated language data, but the great majority of the world's languages have little or none. This dissertation describes work which leverages the detailed and accurate morphosyntactic analyses available for English to improve analytical…
