High variability pronunciation training (HVPT) has been found to be successful for training various segmentals, such as the challenging /l/-/[voiced alveolar approximant]/ contrast, and suprasegmental features such as tone and pitch accent. These studies have found that HVPT is an effective method not only in helping learners improve their…

Language learning is a complex issue of interest to linguists, computer scientists, and psychologists alike. While the different fields approach these questions at different levels of granularity, findings in one field profoundly affect how the others proceed. My dissertation examines the perceptual and linguistic generalizations regarding the…

This qualitative study explores the roles that undergraduate Spanish as a second language (L2) learners ascribe to their identities, backgrounds, sociocultural contexts, and imaginations in the development of their ideal second language (L2) selves (Dornyei 2009), rooted L2 selves (MacIntyre et al., 2017) and investment (Darvin & Norton, 2015;…

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 paper was to study the effectiveness of language acquisition using speaker instruction and listener instruction and examining the emergence of bidirectional intraverbals using a non-sense language. Current research suggests that speaker type instruction is more effective in aiding untrained relations (Contreras et al., 2020;…

This dissertation examines the acquisitional process of middle se constructions by English- and Korean-speaking L2 learners of Spanish. Although clitic se is well known for its multifunctionality, there is a general tendency in the literature to analyze any use of "se" as a reflexive marker. This tendency is especially prominent in the…

Previous studies on second language (L2) phonetic acquisition in early bilingual learners have mainly examined immigrants to the L2 country; however, with recent growing dual-language immersion programs, the immersed bilingual group emerged and required more attention in the research. This study aims to investigate vowel patterns of young…

The meaning of positive polar questions (PPQs) is relatively straightforward, so the truth conditions of PPQs can be decided easily. In contrast, the meaning of negative polar questions (NPQs) may vary, and simple yes-no answers to NPQs have seemingly unpredictable interpretations. For example, a simple yes answer to a PPQ like 'Did you have lunch…

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").…

Previous research has shown that language learners tend to produce fewer and less-natural multi-word sequences (MWSs) compared to native speakers of the same language. In the present study, collocational processing was investigated in a sentence reading task. Specifically, the familiar collocations were predicted to modulate the P3 mean amplitudes…

A considerable amount of research has emerged in recent years concerning second language (L2) learner sensitivity to various information types. From this, Clahsen and Felser proposed the Shallow Structure Hypothesis (SSH) to account for increased learner sensitivity to certain kinds of non-structural (e.g., contextual, discoursal, semantic, and…

This study investigates the effects of native language experience and phonetic properties on the discrimination of labial-velar versus labial and velar contrasts, as well as voicing contrasts in labials, velars, and labial-velars. Research indicates that phonological perceptions are influenced by native language experience and the specific…

Researchers found dual language programs allow students to acquire a second language while building positive cross-cultural beliefs. However, there are inconsistencies between what research shows and teachers' perceptions of success. The problem was a gap in academic achievement between both English Language Learners (ELL) and non-ELL students…

To date, most classroom-based research into the learning of a third language (L3) in the US has examined patterns of acquisition among various groups of bilinguals. Situated mainly within the context of "Portuguese for Spanish Speakers" (PSS), studies typically group learners based on the sequence / age of onset of their main background…

This study investigates acoustically one of long-term debated phonetic characteristics, the so-called Arabic voiced pharyngeal fricative /[voiced pharyngeal fricative]/. Most recent studies have found the Arabic pharyngeal to be approximant, while others have categorized it as a stop in careful speech, and still others have suggested it is a…
