This dissertation study explores a young Japanese heritage language speaker's learning process of formal writing in Japanese. With a rapid increase in immigrants into the U.S. and growing importance of diversity, many researchers have shown interest in immigrant children, i.e., heritage speakers, from educational and research perspectives and have…

It is acknowledged that English language learners (ELL) perform lower than their non-ELL peers and that their lack of language acquisition impacts their graduation rates. However, the approaches taken to reduce the achievement gap between ELL and non-ELL students varies widely. To maximize ELL graduation rates, content area and ELL teachers need…

This dissertation examines native speakers' word recognition of, differentiation between, and social attitudes toward varieties of Arabic. It is a particularly interesting test case because of the Arabic unique regional variation situation and the available literature lacks data on how Arabic speakers perceive different accents, with a particular…

Research shows that sojourning L2 learners are often eager to speak with their native-speaker peers, but they may not realize how these interactions differ from their experiences in the L2 classroom. Using the Communication Accommodation Theory (Giles & Ogay, 2007) as a guiding principle, this mixed-method study aims to, at two different time…

The goal of this study is to contribute to the field of Japanese pedagogy by examining how Japanese native speakers and learners of Japanese as a foreign language with American cultural backgrounds take stances in discussions in Japanese. As stancetaking is a fundamental human behavior (Du Bois & Karkkainen, 2012; Iwasaki, 2015; Kiesling,…

This study examines the effectiveness of study abroad and pragmatic instruction on L2 learners' acquisition of the speech acts of requesting, thanking, and refusing. In the study, speech acts produced by L2 learners of Spanish who studied abroad for six weeks in Buenos Aires, Argentina and L2 learners who received eight weeks of pragmatic…

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…

The purpose of this dissertation is to answer the following question that falls in the intersection of philosophy of language and epistemology: is there any distinctive kind of knowledge that one might possess, merely in virtue of being a native, competent speaker of a certain natural language? When this is expressed as a question specifically…

Mandarin lexical tone learning has repeatedly been identified as a difficult linguistic feature for non-native speakers of tonal languages like English, even for native English learners of Mandarin at high proficiencies (e.g., Pelzl et al., 2019b). Sound perception training has been shown to help native English speakers perceive lexical tone…

The purpose of this phenomenological study was to uncover and understand international graduate students' experiences with "microaggressions" that stem from "native speaker fallacy;" microaggressions are the subtle discriminatory behaviors executed toward marginalized groups and native speaker fallacy is the false belief that…

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").…

As there is a growing population of non-native speakers worldwide, facilitating communication involving native and non-native speakers has become increasingly important. While one way to help communication involving native and non-native speakers is to help non-native speakers improve proficiency in their target language, another way is to help…

Usage-based Phonology proposes that language users' knowledge is stored in the form of exemplars reflecting experience of language usage. Exemplars encompass all visual and auditory information perceived during a language interaction, but few studies have examined the role that visual information plays. This dissertation addresses this question…

The Perceptual Assimilation Model (PAM) (Best, 1995) claims listeners directly perceive articulatory gestures of the vocal tract rather than acoustic/auditory signals. Accordingly, the articulatory similarities and discrepancies between native and non-native sounds determine the perceptual assimilation patterns of non-native sounds. This study…
