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?…

There is a lack of research about the effective methods English language learners' (ELLs) teachers can use to motivate students to learn English as a second language by transmitting the importance and how they ensure successful student outcomes in all four language domains. Data that leads to effective motivational methods for English language…

Do assimilationist restrictions on a minority language lead to greater national unity or a more rebellious minority population? Under what conditions might short-term backlash to language assimilation evolve into greater national unity in the long term? While much of the literature on ethnic politics implicitly treats language simply as an…

Pidgins, narrowly defined, are auxiliary languages reserved for communication with linguistic outgroups. Although implicitly recognized as a class of languages by many linguists, there has been little systematic typological investigation of pidgins. This dissertation presents the first large-scale typological study of morphology and functional…

Increasingly, speakers of minoritized languages around the world are becoming uprooted due to economic pressures, political forces, and environmental destabilization. As communities leave their traditional homelands, they often experience accelerated language shift. Although youth are in a critical position to further transmit their languages to…

Research in first-language (L1) sentence processing has found evidence that language comprehenders use binding condition A as a filter to rule out noun phrases that are binding-inaccessible before proceeding with the task of finding the correct antecedent. Sturt (2013) notes that this strategy does not appear to apply to advanced speakers of…

This dissertation is a quantitative analysis of language proficiencies through the lens of the dynamic model of multilingualism, using survival analysis to evaluate time until thresholds of foreign language proficiency are reached and nonparametric tests (Wilcoxon signed rank and Kruskal-Wallis) to compare proficiencies at distinct time intervals…

The study explores the attitudes of undergraduate Flagship students in the United States towards Arabic-accented speech in English. It examines the Familiarity Principle among these students and analyzes their attitudes based on socio-intellectual status, aesthetic quality, and dynamism of Arabic-accented speech. The study also discusses the…

Individuals with lower proficiency in a second language tend to produce more disfluent speech patterns in the second language. Speech disfluencies refer to interruptions in the forward flow of speech and are distinct from the colloquial use of "fluency," to characterize knowledge of a language. Prior research indicates that some speech…

The dissertation presents a pioneering investigation into child speech among Bikolano children. It aims to address the underdescription and underdocumentation of Child Bikol as spoken in the Philippines. Bikol, an Austronesian macrolanguage, often coexists with more dominant languages, making Bikolano children both emergent multilinguals and…

Reduplication, the copying operation employed in natural language morphophonology (e.g., Ilokano pluralization, [kaldin] 'goat'; [kal-kaldin] 'goats'; Hayes and Abad, 1989, p. 357), creates repetition structures within surface word forms. Though reduplication and surface repetitions have been extensively studied, two questions remain unresolved.…

This dissertation investigates how parametric variation of linguistic properties leads to similarities and differences in language processing across the levels of words, grammatical features, and sentences. For a truly generalizable theory of psycholinguistics, the languages surveyed should not be constrained to English (Garnham, 1994; Norcliffe…

Counterfactuals are a type of conditional sentences used to convey situations that do not correspond to reality. Tense morphology is a core ingredient to encode counterfactuals in English and most Indo-European languages. Mandarin Chinese (hereafter Chinese) lacks tense morphology and does not require counterfactuals to be formally distinguished…

Learner corpus research has expanded from focusing primarily on English as a second language (L2) to include languages such as L2 Spanish, reflecting the growing importance of corpus linguistics in second language acquisition (SLA) research. In this context, and because prompts are the means by which learner corpora gather their texts, it has…

The number of English language learners (ELLs) has increased. The problem is ELLs in a middle Tennessee Charter School network meet challenges in achieving English proficiency, thus limiting academic and social prospects. The purpose of this quantitative correlational study was to determine if there was a relationship between leader-led…
