In two visual world eye-tracking experiments, this dissertation examines the role of literacy on predictive processing during spoken language comprehension. Previous studies have shown that comprehenders can use morphosyntactic cues available in the input to generate predictions about upcoming information. Recent key findings also suggest that…

This study examined the significance of the mode of delivery--aural versus written--in second language (L2) vocabulary knowledge and L2 comprehension skills. One of the unique aspects of listening comprehension that sets it apart from reading comprehension is the mode of delivery--language input is delivered not visually but aurally. Somewhat…

This dissertation explores clear speech which is defined as a specific speaking style people adopt when fluent communication could be compromised for various reasons. Although acoustic properties and their perceptual benefits of clear speech produced by monolingual speakers of English are well documented, there has only been a small body of past…

The current study explored individual differences in sensitivity to sub-phonemic variation of acoustic cues in the perception of a native language (L1) category in order to test the hypothesis that second language (L2) learners' different sensitivity to the L2-relevant acoustic dimension in L1 perception could explain individual variability in…

Individuals with aphasia (IWA) often exhibit challenges in single word reading as well as in reading comprehension. Recently, eye-tracking technology has become instrumental in delving deeper into reading behaviors. Specifically, it has illuminated the differences in word reading and comprehension abilities among aphasic English speakers. However,…

The present dissertation intends to investigate the syntactic nature and L2-acquisition of passive sentence structure in two Romance varieties, Italian and Spanish. First, I will present an analytic proposal couched within the Generative Approach (Chomsky, 1957, and subsequent work); from there, and following Perlmutter and Postal's (1977)…

Gestures and other bodily movements are frequently used as instructional strategies in second language classrooms. Research has demonstrated that gestures are an effective strategy to improve L2 vocabulary recall. However, previous studies have only used vocabulary items that are known to participants in their native languages. Additionally,…

This qualitative case study of a high school world language (WL) classroom with flexible language boundaries (Cummins, 2012; Creese & Blackledge, 2010; Garcia & Li Wei, 2014; Turnbull & Daily-O'Cain, 2009) examines how proficient L1 readers constructed meaning from authentic L2 text as emerging bilinguals. Grounded in sociocognitive…

In the "Sound Pattern of English," Chomsky and Halle (1968) posited that English orthography, despite the complexity in how it relates to phonology, is in fact more "optimal" in at least one aspect: how it relates to morphology. A root or stem tends to maintain a constant visual form across words built upon it even as its…

Prior research has extensively explored audiovisual speech perception and literacy skills in various linguistic contexts. Studies have shown that children's ability to integrate auditory and visual speech cues plays a crucial role in language acquisition and development (Erdener & Burnham, 2013; Lalonde & Werner, 2021). Furthermore,…

At schools in the Unites States, English-centric hegemonic policies often hinder emergent bilingual students from fully applying their linguistic skills to read non-fiction texts. This phenomenon necessitates investigation into how culturally sustaining pedagogy (CSP) can be utilized to support fifth-grade bilingual students' understanding of…

Items in the mental lexicon have three storage and processing strata, the concept, lemma, and lexeme, which equate to semantic, syntactic and phonological information. Lexical items relate to each other at each stratum. Bilingual lexicons, which contain items from all languages, may contain cognates, items sharing concepts and with overlapping…

This dissertation examines investment in language learning, especially how that investment looks over the entirety of a learner's target language-related journey. It investigates investment, in terms of positive and negative relationships and experiences, both at one point in time and over time, as well as how investment may be linked to a measure…

This exploratory research study analyzed the relationships between attitude, preference, and achievement of English Language Learner (ELL) students in high school from Brazil. The study presented what relationships exist between attitude, preference and achievement in reading for both L1 Portuguese, and L2 English. The Middle and Secondary Reading…

U.S. higher education attracts many international graduate students--particularly those from China today where many of them become international teaching assistants (ITAs) in science, technology, engineering, and math (STEM) fields, which not only benefits the students, but also our country as a whole. However, unfortunately, the issue of the…
