Oral communication skills are vital for adult English language learners, especially in daily activities and when securing employment (Parrish, 2015). Pronunciation instruction has been shown to improve learners' intelligibility and communication abilities (Darcy & Rocca, 2022; Thomson & Derwing, 2015), underscoring the significance of…

Co-speech gesture in monolinguals has been linked to several cognitive processes: prompting memory stores, conveying spatial concepts, searching for lexical equivalents, and supporting rhythm and cohesion. The production of co-speech gesture also occurs in spoken language bilinguals. Studies have demonstrated that bilinguals fluent in American…

Dynamic visuospatial support (DVS) is an effective tool for helping people learn linguistic tones (Hannah et al., 2017, Morett et al., 2022, Zhen et al., 2019), and learn words with these tonal categories (Baills et al., 2019, Morett et al., 2015). Progress in the field of embodied cognition and learning has led to recent emphasis on the pitch…

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,…

Nonverbal behavior is essential in human interaction (Gullberg, de Bot, & Volterra, 2008; McNeill, 1992, 2005). For second language speakers, nonverbal features can be helpful for successful and efficient communication (e.g., Dahl & Ludvigsen, 2014). However, due to the complexity of nonverbal features, language testing institutions have…

The purpose of this research was to explore the perceptions of non-Arab preschool teachers' experiences in assessing Arabic-English dual language learners (DLLs) in classrooms using a well-established, teacher scored authentic assessment of early childhood holistic development. Moreover, this study explored parents' experiences by discussing these…

Adolescent newcomer students bring a wealth of linguistic and cultural resources to their learning environments--resources that become even more dynamic when combined with those of their peers. While a significant body of research has explored students' deployment of multilingual resources through translanguaging, most of this work does not…

This study examined the effect of a 1-day, 6-hour key word signing (KWS) workshop on in-service special education teachers' and speech-language pathologists' (SLPs) (a) skill identifying American Sign Language (ASL) signs; (b) skill producing ASL signs; (c) use of KWS in the classroom or therapy room; and (d) perceived changes from taking part in…

American Sign Language (ASL), like many different signed languages, has a systematic way of using pointing signs for multiple types of nominal reference. Possibly the most basic function of pointing is to indicate, direct and modulate reference to physical objects located in proximal and distal areas called exophoric demonstratives. This study…

This present study closely examines a particular type of institutionalized interactions for second language (L2) learning, namely one-on-one instructional sessions between instructors and learners of Japanese at an intensive summer study abroad program in Japan. During these sessions, both instructors and learners employ various form-focused…

This dissertation discusses the gestures produced by students as they learn about the inorganic chemistry topic of symmetry and group theory. Also included is an overview of the development and implementation of a symmetry and group theory laboratory activity, as well as an investigation seeking to promote gestural mimicry and uncover design…

Some types of semantic content have a potential or a requirement to project, i.e., to get interpreted outside the semantic scope of various operators such as negation, conditional and question operators, modals, etc., despite appearing to be in their syntactic scope. But what is the exact classification of projecting content, and how do we know…

The goal of this dissertation is to better understand the targets of vowels in speech production. Three experiments investigate vowel production in non-native speech, probing how new vowel categories, and thus targets, are formed. Three research questions are addressed: (1) Do vowels have articulatory targets (as predicted by Browman &…

Categorization of objects' parts varies across human populations. This dissertation provides evidence that the linguistic and non-linguistic aspects of this categorization are closely linked. English speakers apply mostly terms with abstract geometrical meaning, like "top," to the parts of any arbitrary object. However, in the languages…

The process of spoken word recognition is influenced by both bottom-up sensory information and top-down cognitive information. These cues are used to process the phonological and semantic representations of speech. Several studies have used EEG/ERPs to study the neural mechanisms of children's spoken word recognition, but less is known about the…
