Acquisition of the perfective marker "-le" in Mandarin Chinese is a daunting task for second language learners. To date, there has been no consensus on what it is about "-le" that makes it such a challenge to learners. This study investigates the acquisition of "-le" from both a lexical perspective and a discourse…

This dissertation explores first language (L1) transfer and second language (L2) transfer processes and models, such as the full transfer/full access model (FT/FA), the representational deficit/interpretability hypothesis, and the feature reassembly hypothesis (FRH). The typological proximity model (TPM), the cumulative enhancement model (CEM),…

Construction Grammar has been a prominent framework in linguistic research for nearly three decades, attracting scholars from various disciplines, including language acquisition, corpus linguistics, and psycholinguistics. While considerable progress has been made in understanding the first language (L1) construction learning of various languages,…

This study aims to identify whether the acquisition of the English copula by Arabic-speaking learners of English provides evidence for a performance or representational-based account of errors. The representational theory tested in this study is the Interpretability Hypothesis (Tsimpli & Mastropavlou, 2007) which proposes that language…

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…

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…

In the field of Instructed Second Language Acquisition (ISLA), written corrective feedback (WCF) has been shown to play a facilitative role in improving written accuracy (e.g., Ashwell, 2000; Ferris & Roberts, 2001; Ferris, 2006; Sheen, 2007; Bitchener, 2008; Liu & Brown, 2015). However, studies that examine the effects of different types…

One of the most researched challenges in learning Spanish is the acquisition and use of the past aspect, namely, the preterit and imperfect. L2 learners encounter this challenge due to differences in how native English and Spanish speakers view past events. Numerous studies on the Spanish past aspect have analyzed L2 learners' past aspectual…

The current project investigates developmental aspects of acquiring locative verb constructions in English as a second language. Locative verbs, such as "to pour," "to spill," "to spray," and "to sprinkle," constitute a prototypical case of an overgeneralization problem in language learning: Whereas some of…

This study compares monolinguals and different kinds of bilinguals with respect to their knowledge of the type of lexical phenomenon known as collocation. Collocations are word combinations that speakers use recurrently, forming the basis of conventionalized lexical patterns that are shared by a linguistic community. Examples of collocations…

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 general goal of this dissertation is to explore two decades-long second language (L2) acquisition issues: whether and to what extent the L2 learner's first language (L1) and Universal Grammar (UG) respectively play a role in L2 development. Targeting English verb phrase ellipsis (VPE) and "wh"-extraction out of VPE, four…

This dissertation provides a language processing perspective on the study of second language acquisition (SLA) of tense and aspect. Of special interest are the universal vis-a-vis language-specific dimensions of temporal and aspectual semantics involved. According to the Aspect Hypothesis (AH, e.g. Andersen & Shirai, 1994), the initial…

This dissertation investigates the neural and behavioral correlates of grammatical agreement computation during language comprehension in native English speakers and highly advanced L1 Spanish-L2 English bilinguals. In a series of electrophysiological (event-related brain potential (ERP)) and behavioral (acceptability judgment and self-paced…

This dissertation compares the knowledge of Russian Verbal Aspect in two types of learners enrolled in college level Russian courses: foreign language learners of Russian whose native language is English and heritage language speakers of Russian whose dominant language at the time of study is English. Russian Aspect is known to be problematic both…
