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…

Purpose: The purpose of this study was to explore potential differences in suprathreshold auditory function among native and nonnative speakers of English as a function of age. Method: Retrospective analyses were performed on three large data sets containing suprathreshold auditory tests completed by 5,572 participants who were self-identified…

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…

The purpose of this study was to explore the effect of the listener's education and occupation on intelligibility, comprehensibility (ease of understanding), and accentedness in speakers of Russian-accented American English (RA), Southern-accented American English (SA), and General American English (GAE). Native English listeners (N=126) rated…

This paper reviews and discusses research on notetaking during academic listening conducted in both first (L1) and second language (L2) contexts and is organized into two main categories: research that is beginning to impact English for academic purposes (EAP) classrooms and that which has yet to make an impact on EAP, but should. Overall, I…

Research on intelligibility in international encounters has long focused on issues of pronunciation to the detriment of factors such as linguistic co-text and extralinguistic context, which are comparatively well-studied variables in intelligibility research concerning L1 listeners. This paper seeks to expand the scope of international…

English-medium instruction (EMI) has burgeoned alongside two decades of L2 self-regulated learning research. In both areas, listening remains under-researched, longitudinal designs are under-employed, and in-depth studies are necessary to unpack learner development. In a context believed to initiate self-regulated learning, the current study…

This study investigated the relationship between the level of cognitive-linguistic difficulty of task input and the size of the cross-linguistic relationship for academic listening comprehension in emergent bilinguals. It was theoretically motivated by task-dependent cross-linguistic interaction frameworks. We hypothesized that task item sets that…

The current replication study aims to examine the effects of learners' attention to lexical and grammatical forms on meaning comprehension while listening to a passage in Spanish. The registered protocol and materials in the aural mode from Morgan-Short et al.'s (2018) multisite replication study were used, with first language (L1) Chinese-second…

Research in metacognitive listening strategies in first language (L[superscript 1]) listening is in its infancy. The research presented here, which is the first study in a larger research program, compares the strategies L[superscript 1] students in the US say they do in the classroom with the strategies L[superscript 2] students say they use, as…

This study investigated L2 Korean speakers' self-assessment of speech comprehensibility and accentedness, including a conceptual replication of Trofimovich, Isaacs, Kennedy, Saito, and Crowther (2016, Experiment 1) and exploratory analyses of individual differences in self-assessment. L2 Korean speakers (N = 198) self-assessed their…

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)…

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…

In second language (L2) research, the lexical unit is often defined as a base word plus inflectional and derivational forms through Level 6 of Bauer and Nation's framework (WF6). WF6 use has been justified by the assumption that once a form is known, recognition of other WF6 members requires little extra effort. A more lenient view holds that an…
