In two visual world eye-tracking experiments, this dissertation examines the role of literacy on predictive processing during spoken language comprehension. Previous studies have shown that comprehenders can use morphosyntactic cues available in the input to generate predictions about upcoming information. Recent key findings also suggest that…

The ability to speak in a second language (L2) requires a certain level of linguistic proficiency, but the ability to "live" in a second language requires a certain level of "sociolinguistic" proficiency. L2 sociolinguistic variables present acquisitional challenges for language learners, since informal discourse features are…

This dissertation examines heritage language learners of Spanish enrolled in university Spanish courses, focusing on their strategic use of suprasegmental speech features in two speaking tasks. The research investigates attitudes' influence on heritage language learners' speech production in different task types. Participants engaged in two…

The present study contributes to our understanding of the effects of age and type of linguistic input in the acquisition of Spanish as a second language in adulthood. I examine the Spanish syntax (word order) of three groups of speakers, monolingual Spanish speakers from Mexico and two bilingual English-Spanish speakers born and raised in the…

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…

Adult first language (L1) English speakers who are advanced second language (L2) learners of Spanish demonstrate near-ceiling levels of accuracy for some features of Spanish, such as [Person] and [Number] for verbs (McCarthy, 2012; Rodgers, 2011). While for other features, such as [Aspect] for copulas (i.e. ser and estar), and [Person] and…

Millions engage in learning a Second Language (L2) using their mobile devices with a wide range of success. Concomitantly, there exists a growing interest in research on the effects of mobile-assisted language learning and predictors of learner outcomes (e.g., Loewen et al., 2020; Sudina & Plonsky, 2023). However, few of these apps and studies…

This dissertation explores Spanish copular verbs, "ser" and "estar" (both 'to be' in English), in pre-adjectival contexts within two Spanish varieties: first-language (L1) Chilean speakers from Santiago (N = 29) and second-language (L2) English-speaking learners studying in Chile (N = 31). Bridging sociolinguistics and second…

This research documents the experience of 12 local leaders implementing an oral curriculum over 13 months in Karnataka, India. These leaders were Change Agents interested in influencing a community with new information. They created audio materials referred to as "content" in their group's mother tongue: In a Kannada-Telegu mix for the…

Dual language (DL) schools provide literacy in students' native languages; however, it is unknown if there is a focus on oral language (OL) development, an essential component for emergent bilinguals'(EB) literacy development. The purpose of this mixed-methods case study is to understand what DL teachers in Virginia know about OL instruction when…

Practice is necessary for developing oral English proficiency, but many Chinese learners of English lack the self-confidence to practice oral English; furthermore, students' self-confidence deficiency is perpetuated by insufficient oral English proficiency. The purpose of this qualitative case study was to discover pedagogical practices that break…

It has long been recognized that collocations, or chunks of formulaic language, are essential and frequent in language (Henriksen, 2012; Sinclair, 2004). Therefore they are a crucial part of Second Language Acquisition (SLA). Linguistic scholars Pawley y Syder (1983: 192) remark that "in order to know a language, the [second language] (L2)…

While L2 production is widely understood to show traces of L1 interference and general cue availability, the role of visual cue strength on L2 production is previously unstudied. As such, this experiment compares the production of 10 L2 Italian speakers' intervocalic /p/ - /pp/ and /k/ - /kk/ contrasts, to see if the more visible labial pair is…

This manuscript-based dissertation is comprised of three interrelated longitudinal studies on Spanish language growth and deceleration and its impact on English language growth and English reading skills in bilingual children. Chapter 1 introduces the manuscript-based dissertation and provides the background on existing, longitudinal work of dual…

Negation has been researched in second language acquisition in several languages (Bernini 2000; Donaldson 2017; Eskildsen 2012). However, there are very few studies that have discussed the acquisition of negation in L2 Spanish. In Alexandrino's (2010) dissertation, Grammaticality Judgment Tasks are employed to indicate that the acquisition of…
