This study examines accent biases in hiring practices among educators in U.S. schools. Using quantitative methods, the research investigates whether bias levels and accent types influence hiring decisions. The study, involving 216 hiring managers from various school sectors, found no significant correlation between bias levels (audio versus video)…

F0 contours convey multiple types of information, including lexical and post-lexical meanings, as well as affective and socio-indexical indicators. This dissertation investigates the interaction between lexical tone and sentence-level intonation in Thai, focusing on how sentence position influences the acoustic realization and perceptual…

Tact is the most important verbal operant (Skinner, 1957) due to the uniqueness of stimulus control and its role in facilitating acquisition of another verbal (e.g., mands, intraverbals) and nonverbal (i.e., listener) operants (Sundberg, 2015). Teaching tacts to children with ASD and the research on this area, however, are largely focused on…

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…

Pitch discrimination, or the ability to differentiate stimuli using auditory frequency, may be an important correlate of language acquisition. Research consistently finds that children with autism spectrum disorder (ASD) have differences in auditory discrimination abilities. However, studies linking these abilities to delays or impairments in…

A listener's explicit knowledge of the links between phonetic variants and social categories can be referred to as their sociophonetic knowledge. The goal of this dissertation was to directly examine the degree to which sociophonetic knowledge influences listeners' ability to process and encode lexical tokens produced in different accents, with…

This dissertation examines how listeners' knowledge of interspeaker variability guides their generalization of perceptual learning in multi-talker listening. A series of perceptual learning experiments are conducted to evaluate whether listeners generalize what they have learned about a previous talker's production of sibilants and stop VOT to…

This dissertation examines whether and how psycholinguistic priming, and social knowledge are integrated in the identification of sociolinguistic variants. Using the English variable (ING), the alternation between -ing and -in' (e.g. thinking vs. thinkin') as a testing ground, this dissertation probes whether and how individuals utilize…

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)…

Dyslexia is a common, lifelong, language and brain-based learning disability that can affect language processing and may lead to difficulties with reading, spelling, and writing. Symptoms of dyslexia include problems with decoding or single word reading, poor reading fluency, and poor spelling (IDA, 2018a). The use of Elkonin Sound Boxes (ESBs) is…

Previous research has shown a relationship between robust neural encoding of speech by the auditory brainstem and children's phonological abilities. Two areas of brainstem encoding this work has included are the ABR dimensions of consistency, or how similar responses are to a repeated stimulus, and differentiation, or the degree to which responses…

This study compared the effects of listener training and tact training on the emergence of intraverbal responses in the form of foreign language equivalents of the native language. The study was based on Skinner's verbal operants with a focus on intraverbal responses. All participants received listener training and tact training after which a…

Stuttering is a developmental speech disorder characterized by interruptions of fluency. A large body of research suggests that stuttering occurs due to a reduced ability to generate timing signals in order to sequence speech sounds. One piece of supporting evidence for this is that when speaking along with an external timing source like a…

The present study sought to evaluate trial designs and training designs that are commonly used in popular commercially available computer-assisted language-learning (CALL) programs. The first two experiments (Experiment 1a and 1b) compared the effects of passive viewing and active student response methods in vocabulary learning. Contingencies on…

This study investigated the involvement of the Social Agency Theory within a multimedia learning environment to improve English language proficiency. The primary aim of this study is to find the effects of designing language learning instructional videos following the embodiment principle on language learners' motivation, cognitive load and…
