This study investigates the acquisition and maintenance of periphrastic and se-passives in second language (L2), heritage (HS), and (Spanish-dominant) native Spanish speakers (NS) by addressing: (i) How accessible are Spanish periphrastic passives (which also exist in English) and se-passives (unique to Spanish) for L2ers and HSs in production?…

This dissertation investigates the interplay between the implicit knowledge that learners have of a nonnative language and their processing of that language, examining two types of relative clauses (RCs) in English: gapped RCs (e.g., "the man that they hired") and resumptive RCs (e.g., *"the man that they hired him").…

Second language learners constitute a significant and expanding portion of the global population and there is a growing demand for tools that facilitate language learning and instruction across various levels and in different countries. The development of large language models (LLMs) has brought about a significant impact on the domains of natural…

Understanding how native speakers acquire the phonological patterns in their language is a key task for the field of phonology. Numerous studies have suggested that phonological learning is a biased process: certain phonological patterns are easily accessed and learned by the speakers, while others show acquisition difficulties. These differences…

The main purpose of this dissertation is to examine the (in)effectiveness of the Usage-based grammar approach through explicit instruction of adverbials in the US educational context. One area that can complicate the question of native speakers' grammar knowledge is their awareness of grammatical terms and their functions. Along with exploring…

The present dissertation brings together research on heritage language acquisition and bilingual education and makes inroads into the limited research on heritage language development in school-aged bilingual children. This study explores how bilingual education, patterns of exposure, and lexical frequency shape adolescent Spanish heritage…

This dissertation investigates the morphological and morphosyntactic processing of case-marking by native and nonnative speakers of Turkish, through behavioral and electrophysiological responses. The study explores the locus of case processing costs during first (L1) and second language (L2) word recognition both in isolation and in sentences. It…

Subject-verb agreement constitutes a robust characteristic of French. However, especially at beginner and intermediate levels, second language (L2) learners might substitute or fail to recognize an infinitive for a conjugated verb, or a 3rd person singular form for a plural form, as "Les enfants mangera" (The children will eat--3rd…

This thesis examines whether native, heritage, and L2 speakers of Spanish engage a morphological layer of representation in the processing of inflected words, and whether they do so with both regularly- and irregularly-inflected words. Also examined is whether this tendency towards compositional (i.e. morphological rule-based) processing is…

One of the central questions in recent second language processing research is whether the types of parsing heuristics and linguistic resources adult L2 learners compute during online processing are qualitatively similar or different from those used by native speakers of the target language. While the current L2 processing literature provides…

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 dissertation explores why grammatical structures are better learned implicitly or explicitly by investigating differential object marking (DOM) in Spanish. To address the effectiveness of implicit versus explicit instruction in the classroom, the researcher focused on two of the main features that constrain DOM in Spanish: animacy and…

English speakers talk and think about Time in terms of physical space. The past is behind us, and the future is in front of us. In this way, we "map" space onto Time. This dissertation addresses the specificity of this physical space, or its topography. Inspired by languages like Yupno (Nunez, et al., 2012) and Bamileke-Dschang (Hyman,…

Recent research has demonstrated that L2 learners and heritage speakers might have two different profiles in terms of their syntactic, morpho-syntactic, and lexical-semantic knowledge of a target language (Montrul, 2004, 2006, 2010; Montrul, Foote, & Perpinan, 2008). However, the most influential of the major studies have been limited to…

Many people want to learn a foreign language, but issues of time, convenience and cost mean that classes are often insufficient for learners, and increasingly learners are supplementing or replacing their classroom learning with online learning. The majority of existing online language learning systems use the traditional grammar-translation…
