English ditransitive verbs show a complex alternation between the double object construction (DOC, (1)) and prepositional object datives (POD, (2)). This dissertation examines the acquisition, representation, and learnability of the dative alternation among L2 English learners, presenting experimental data from participants with L1 backgrounds of…

This dissertation examines the linguistic behavior of code-switching in three groups of highly proficient Cantonese-English bilinguals. Code-switching refers to alternating between two or more languages within the same sentence or between two sentences. While traditional research on bilingualism often compares bilingual speakers against…

Nawat, the highly endangered indigenous language of El Salvador, is undergoing a revitalization process. This dissertation, conceived within this context, focuses on the second-language (L2) acquisition of features of Nawat pronunciation by learners who have Salvadoran Spanish as their first language (L1). Specifically, I assess the acquisition of…

In English as a lingua franca (ELF) communication, in which English is used as a common language among interlocutors of different first languages, successful communication often features communication strategies that enhance mutual understanding and relationship management. Although prior research suggests that including such strategies in English…

This dissertation investigates Voice Onset Time (VOT), which serves as an essential property for differentiating plosive consonants in L1 and L2 Mandarin Chinese. It surveys VOT variations and demonstrates that they are affected by several phonetic and phonological properties, e.g., lexical tone, place of articulation (POA), speech rate,…

Mixed languages like Media Lengua incorporate grammar from one source language (here, Quichua) but lexicon from another (here, Spanish). Due to their linguistic profile, they provide a unique window into bilingual language usage and language representation. Drawing on sociolinguistic, structural and psycholinguistic perspectives, the current…

This research project sought to explore the influence of English L2 on Spanish L1 in an environment where the L1 (Spanish) is the dominant language. Participants were recruited through voluntary response sampling at the University of Puerto Rico Secondary School (UHS). They completed a language survey on Google Forms that collected general…

A great deal of the research on cross-linguistic phonetic influence demonstrates that a speaker's knowledge of their first language (L1) significantly affects their ability to perceive and produce sounds in any other language. While current studies show that cross-linguistic transfer occurs at the L3 level, some research suggests that properties…

North Kyungsang Korean (NKK) is a pitch accent language in which each word has one of a restricted set of possible tonal patterns, and where the tonal pattern of a given lexical word is not fully predictable. This dissertation reports on a corpus study of accent patterns in existing words and the results of a study in which NKK speakers were asked…

This dissertation presents an instrumental study of variation in fricative voicing in Buenos Aires Spanish (BAS), particularly with respect to the devoicing change of the postalveolar fricative: /y/greater than/[function of]/. It proposes a novel way of determining the completion of this change by comparing the percentage voicing of the…

This dissertation uses the generative framework to study the syntax and pragmatics of word order variation in the Andean Spanish of Bolivia and Ecuador. While Standard Spanish has basic order SVO, in Andean Spanish the object frequently appears in preverbal position, resulting in alternative orders (e.g. OVS). Previous studies have attributed this…

This dissertation compares the phonetic and phonological features of adult non-speakers' productions of words in an endangered Native American language, Oregon Northern Paiute (also known, and hereafter referred to, as Numu), to productions by fluent speakers. The purpose of this comparison is two-fold. The first purpose is to examine the…

This study investigated how the speech act of refusal is realized in Egyptian Arabic by intermediate and advanced American learners of Arabic as a foreign language. It also compared the performance of the learners to that of native speakers of Egyptian Arabic and native speakers of American English. The study aimed to investigate the relationship…
