How can syntactic and learnability analyses inform each other, and thus deepen our understanding of syntax and its acquisition? This dissertation illuminates this question through three case studies in Korean syntax. I examine cases in which two structures that display distinct syntactic properties share extremely similar surface forms, thus…

Noise is a common impedance to easy and accurate speech understanding. In the presence of noise, speech processing mechanisms proceed with partial or ambiguous inputs, and listeners will engage additional cognitive resources to make sense of what they hear. The extent to which this is situation is affected by diminished exposure to a language is…

Syntactic movement is central to mainstream generative theories of syntax (Chomsky, 1957; 1981; 1995; 2001). Under this view, sentences contain words that have moved and words that have not. Children only ever hear words in their moved positions so it is unclear how they could determine the ways these constituents must be merged and moved from…

Mandarin is a tone language that is spoken by billions of people in the world. Despite huge demand, there is a lack of assessment and treatment tools targeting Mandarin speakers with communication disorders. To better understand the speech profile of Mandarin speakers with communication disorders, this dissertation first examined contrastive…

This dissertation examines the associations between pragmatic meaning categories in English and specific realizations of prosodic prominence. It has been well-established that in Mainstream American English (MAE), prominence is often used to convey contrast. A more limited set of studies suggests that prosodic prominence may also be capable of…

During language acquisition, children are tasked with the challenge of determining which words can appear in which syntactic constructions. This has been long recognized as a learnability paradox. On one hand, there are generalizations that children must learn. On the other hand, language is known for its arbitrariness, so children also need to…

Across three experiments, the current study explored how accented speech and coarticulation impact how bilingual listeners comprehend code-switches in speech. Eye-tracking methodology was used to compare responses to single-language and code-switched sentences. Experiment 1 observed how accented speech influenced the costs involved in…

Language production and the execution of motor acts have long been thought to have similarities in the rules of their execution. Recent studies have begun to directly compare these two processes by measuring certain phenomena found in both. Until now, comparisons have only been made in parallel, with different groups of participants and/or tasks.…

The purpose of this qualitative descriptive study was to explore how reading teachers in southern urban schools described their use of prior knowledge and text clues in instructing high functioning ASD students in their use of inferencing to improve their reading comprehension. There were three research questions used in this study: RQ1: How do…

Collaborative learning provides learners with significant opportunities to collaborate on solving problems and creating better products. There has been a growing utilization of adaptive and intelligent systems to support productive learning while promoting collaborative practices. One of the core capabilities of these adaptive and intelligent…

Guided notes in the form of teacher-prepared materials that guide students through the lesson with cues and space have been recommended as a possible aid to support student learning. The present study investigated the results of guided notes on the students' learning achievement, the quality of the students' notes, and the students' perceptions of…

This qualitative practice-based study explores the efficacy of reformed-based science teaching approaches in fostering meaningful student engagement within elementary science classrooms, framed within the science-as-practice paradigm. Utilizing three theoretical frameworks, the Next Generation Science Standards (NGSS) and Ambitious Science…

Code-switching (switching between languages) is a common linguistic behavior in bilingual speech directed to infants and children. In adult-directed speech (ADS), acoustic-phonetic properties of one language may transfer to the other language close to a code-switch point; for example, English stop consonants may be more Spanish-like near a switch.…

The purpose of this quantitative post measure only experimental study was to determine if, or to what extent, the use of emojis by a chatbot pedagogical agent in a threaded conversation is effective in eliciting social presence, human-like, and engaging perceptions by adult learners living in North America. Social presence theory provided the…

Speech is a complex, redundant and variable signal happening in a noisy and ever changing world. How do listeners navigate these complex auditory scenes and continuously and effortlessly understand most of the speakers around them? Studies show that listeners can quickly adapt to new situations, accents and even to distorted speech. Although prior…
