This dissertation presents behavioral studies that target the early syntactic representations of "wh"-movement during infancy and early childhood. Previous studies show that by 20 months-old, infants represent "wh"-movement and use this knowledge to respond to "wh"-questions during language comprehension tasks…

This dissertation articulates and defends a view about linguistic competence called 'variabilism'. According to variabilism, the epistemic demands of full linguistic competence vary in a particular way. More specifically, variabilism holds that different individual lexical application conditions (individually essential metaphysical ways of being…

This dissertation investigates the wide-ranging implications of a simple fact: language unfolds over time. Whether as cognitive symbols in our minds, or as their physical realization in the world, if linguistic computations are not made over transient and shifting information as it occurs, they cannot be made at all. This dissertation explores the…

This dissertation presents a series of case studies concerned with whether the signal in a given set of measurements that we take in the course of linguistic inquiry reflects grammatical competence or performance factors. We know that performance and competence do not always covary, yet it is not uncommon to assume that measurements that we take…

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…

The second language (L2) acquisition of tense, aspect, and mood/modality (TAM) has been widely explored as it holds the promise of a better understanding of the L2 learners' linguistic competences, particularly semantically and morpho-syntactically. This study focuses on the acquisition of the subjunctive mood by L1 English learners of L2 French…

First time college undergraduate students from China face linguistic and cultural barriers when seeking academic help from their faculty members, but there is little research addressing these students' experiences of encountering these barriers, nor how the barriers are overcome. This qualitative transcendental phenomenological study sought…

Chinese has intimidated heritage language learners as it is believed to be notoriously difficult (Liu, 2008). Traditional Chinese education, which focuses on linguistic skills and is mainly acquired by recitation and memorization, tends to drive students from maintaining and regaining their inherited language and culture (Curdt-Christiansen,…

As face-threatening speech acts, requests are of particular interest to second language acquisition scholars. They affect the interlocutors' public self-images, and thus require a careful consideration of the social distance between the interlocutors, their status, and the level of the imposition, factors that are weighed differently in…

Background: Cultural and linguistic competence is widely viewed as a strategy for addressing disparities in health and mental health care. Organizational activities towards the integration and implementation of cultural and linguistic competence span the gamut to include training, workforce development, policy development and standards that inform…

This study examined the linguistic competence in Korean of Korean heritage language learners (HLLs), compared to English-speaking non-heritage language learners (NHLLs) of Korean. It is unclear and controversial as to whether heritage languages learners are exposed to early but are interrupted manifest as L1 competence or share more…

This dissertation studies the acquisition of verb argument structure in the basilectal subvariety of Jakarta Indonesian (henceforth, bJI). There are two characteristics of bJI that potentially affect the acquisition of verb argument structure. First, bJI sentences can surface not only in the full frame but also in truncated frames. Second, the…

A basic challenge for research into the neurobiology of language is understanding how the brain combines words to make complex representations. Linguistic theory divides this task into several computations including syntactic structure building and semantic composition. The close relationship between these computations, however, poses a strong…

The present study investigates the degree to which social, experiential and usage-related factors correlate with Spanish linguistic competence among adult Hispanic Heritage Language (HL) speakers in the United States. Two online survey instruments were developed in furtherance of this research aim: a Likert-scale survey measuring five areas of…
