All communication systems rely on sets of rules that must generally be followed for successful communication to be possible; in the case of human language, these rules are given by the grammar. However, despite these rules, there is considerable variation that has been noted across the grammar. In this dissertation, I explore one understudied…

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 field of Heritage Language has experienced a great deal of advancement in the past few decades. Much research effort has been dedicated to analyzing and understanding different aspects of heritage language speakers, but less work has been done in the topic of pedagogical approaches. The few recent studies on pedagogical approaches have focused…

Interaction has received attention in different fields of applied linguistics. In the field of Second Language Acquisition (SLA), scholars have perceived interaction as a platform where L2 learners can engage in language experimentation. It has been considered in light of Long's (1981) Interaction Hypothesis, which posits that negotiation of…

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…

This dissertation examines the extent to which lexical aspect and grounding influence the acquisition of tense and aspect by ninety-four instructed adult learners of Italian in two academic settings in North America. The semantic notions of tense and aspect have been extensively investigated in the domain of second language acquisition. After more…

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 is a grammar which provides a detailed linguistic description of the phonology, morphology, syntax, discourse, lexicon and cultural environment of the Mehek language and its speakers. Mehek is a language spoken in Papua New Guinea by approximately 6300 people. It belongs to the Sepik language family, Tama branch. The theoretical background…

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…

The growing presence of Synchronous Computer-Mediated Communication (SCMC), defined as 'real-time, synchronous conversation that takes place online' (Baralt & Leow, 2016, p. 200), via video-chat programs such as Skype in online language courses has been documented in the literature (Ziegler, 2016c). While research up to now has shown that…

In the present day Mandarin Chinese has become a commonly taught language in the U.S. Mandarin is widely taught in colleges and universities; K-12 Chinese programs, including immersion programs, have also grown rapidly. However, to date little research has been conducted on the latter programs. This study examines immersion programs in elementary…

The present study used individual growth modeling to examine the role of specific forms (i.e., receptive, expressive, and definitional vocabulary and grammatical skill) and levels of oral vocabulary skill (i.e., 25th, 50th, or 75th percentile) in phonological awareness growth during the preschool and kindergarten years. Sixty-one,…

Foreign language educators have been striving to improve practices that support language teaching for adults for many years. Common knowledge insists that children are better language learners than adults. Creation of the new field of neurolinguistics at the end of the 20th century brought about new opportunities for both teachers of foreign…

This study describes the grammar of the Ch'orti' Maya language as it appears in a collection of oral literature. I collected the stories that form the basis of this study in and around Jocotan, Guatemala, during 2004 and 2005. I worked with bilingual story-tellers to make audio recordings of the original Ch'orti'-language tales, produce textual…
