Despite some rises and falls in the numbers due to various reasons, including the political climate in the Trump era and the COVID-19 pandemic (Laws & Ammigan, 2020), each year universities in the United States host a large number of multilingual international students from different parts of the world. Based on their TOEFL scores, many are…

Language is connected to a people, culture, history, and communicative purpose. One way world language teachers help students explore the intersections of culture and language is through the use of authentic texts, such as films, newspapers, podcasts, videos, music or short stories (see: Pinzon, 2020). While the research points to the success of…

This dissertation explores the effects of frequency on the learning and use of linguistic constructions. The work examines the influence of frequency on form choice in production and meaning inference in comprehension and discusses the effect of each modality on diachronic patterns of change in language. In production, high frequency of a form…

The purpose of the current dissertation is to map the relationships between first language (L1), writing quality, and syntactic complexity, accuracy, lexical complexity, and fluency (CALF) in second language (L2) writing. CALF are characteristics of language production that have been of significant interest in L2 writing research for the past few…

This study investigated Reading Recovery teacher understandings about language and early literacy acquisition by applying a constructivist grounded theory design. Participants were Reading Recovery teachers working across three varied districts in Massachusetts (N=33). The purpose of the study was to engage Reading Recovery teachers in surveys,…

In second language acquisition, it is well known that an early age of onset and an extensive amount of naturalistic input are key elements promoting successful learning outcomes. What is less well known is what outcomes we can expect when the main source of these elements is full-immersion schooling, defined for the purposes of this study as a…

Language is inherently variable, and learner language is particularly variable. The variationist paradigm considers learner language a heterogeneously variable yet inherently rule-governed system. Specifically, learners' alternation between native-like and nonnative-like variants of a variable or invariable target native speaker (NS) form…

English ditransitive verbs show a complex alternation between the double object construction (DOC, (1)) and prepositional object datives (POD, (2)). This dissertation examines the acquisition, representation, and learnability of the dative alternation among L2 English learners, presenting experimental data from participants with L1 backgrounds of…

Many studies evidence the flexibility of speech perception in the first language (L1), which allows rapid adaptation to unfamiliar foreign accents. Two influential studies by Bradlow and Bent (2008) and a follow-up study by Baese-Berk et al. (2013) found that increased variability as a function of the number of talkers and accents facilitated the…

The importance of input on language learning cannot be overstated. One method of providing input to learners at a level that is appropriate for them is called extensive reading, in which learners read an abundance of texts. In practice, for learners of English as a second or foreign language, these texts are often books that have been written and…

Spoken words vary phonetically along a number of dimensions, such as duration, pitch, and vowel quality. Much of this variation is associated with social factors like the dialect, age, or gender of the speaker -- a type of variation termed 'socio-indexical'. Traditional theories of speech perception have seen this socio-indexical variation as a…

Enabling learners to successfully use their second language (L2) in meaningful ways is a critical goal of instruction. Ultimately, most learners want to meet the L2 demands of the contexts in which they will use the language. To accomplish this, learners must develop linguistic knowledge and apply it in a manner that is contextually appropriate…

Despite their permeation in standard French, language variations, such as "argot" and "verlan" are seldom included in the curriculum of French university language programs in the U.S. Variations are often perceived negatively, leading to stigmatization towards the social groups who use them (Bourdieu 1982; Devereaux and Palmer,…

This dissertation examines the linguistic behavior of code-switching in three groups of highly proficient Cantonese-English bilinguals. Code-switching refers to alternating between two or more languages within the same sentence or between two sentences. While traditional research on bilingualism often compares bilingual speakers against…

Nawat, the highly endangered indigenous language of El Salvador, is undergoing a revitalization process. This dissertation, conceived within this context, focuses on the second-language (L2) acquisition of features of Nawat pronunciation by learners who have Salvadoran Spanish as their first language (L1). Specifically, I assess the acquisition of…
