Exploring Cross-Linguistic Speech Perception In Hindi, English, And Romance-Language Through Temporal Dynamics Of Neural Activity, Yuga Kothari
Dissertations, Theses, and Capstone Projects
This study examines the effect of linguistic experience on the neural processing of Voice Onset Time (VOT) in Hindi and Romance language (Spanish and Portuguese) individuals who are bilingual in English and monolingual English speakers using the event-related potential (ERP) Mismatch Negativity (MMN) response. VOT is a linguistic property that measures the time elapsed between the release of a stop consonant and the beginning of voicing, that is, vocal fold vibration of a following vowel. In a double-oddball paradigm, participants’ (n = 41) ERP were recorded while listening to speech sounds differing in VOT. The bilabial short lag stop [p] …
Characterizing The Brain Dynamics And Eye Movement Behavior Of Memory-Guided Saccades: A Preliminary Investigation Of Distractor Influence On Memory-Guided Saccades, Angelo V. Colmenero
Characterizing The Brain Dynamics And Eye Movement Behavior Of Memory-Guided Saccades: A Preliminary Investigation Of Distractor Influence On Memory-Guided Saccades, Angelo V. Colmenero
Dissertations, Theses, and Capstone Projects
Research has helped to shed light on the functional organization and neural mechanisms of distractors on memory-guided saccades. In our current study we have utilized eye tracking and EEG technology to simultaneously record the changes in saccadic eye movement (SEM) behavior and event-related potentials (ERPs) associated with performance on a memory-guided saccade task with distractor conditions. Thirteen healthy control participants (n = 13; 6 female) were tasked to complete 864 memory-guided saccade trials with both visible (white) and invisible (black) distractors presented on a black background before saccade initiation. Compared with the control (black) distractor condition, distractor presentation produced a …
An Erp Study Of Sensory-Linguistic Processing In The Context Of Asd Research, Larissa R. Miller
An Erp Study Of Sensory-Linguistic Processing In The Context Of Asd Research, Larissa R. Miller
Dissertations, Theses, and Capstone Projects
This thesis considers the questions of what is hindering the language development of children with Autism Spectrum Disorder (ASD). Tomasello’s (2003) theory of language development by use necessitates adequate pattern recognition, intention reading and use for language development. Within these areas there are many variables where language acquisition could become derailed, from basic attention, perception and memory to higher cognitive functions, as well as processing speed and synchronization. Although there is a wide range of language abilities for children on the autism spectrum, the one consistently under developed area is pragmatics. One of the key aspects of pragmatic processing is …
Native Language Adaptation To Novel Verb Argument Structures By Spanish-English Bilinguals: An Electrophysiological Investigation, Eve Higby
Dissertations, Theses, and Capstone Projects
Bilinguals have to learn two different grammatical systems. Some aspects of these grammars may be similar across the two languages (for example, the active-passive alternation) while others may exist in only one of the two grammars (for example, the distinction between recent and distant past). This dissertation investigates the degree to which grammar information specific to only one language is available when processing the other language. In particular, the current study focuses on the application of grammatical structures from the bilinguals’ second-learned language to their first-learned language, a direction of language transfer not often investigated. Based on a Shared Syntax …
Executive Dysfunction And Reward Dysregulation: Interactions In Drug Addiction, Kristen Paula Morie
Executive Dysfunction And Reward Dysregulation: Interactions In Drug Addiction, Kristen Paula Morie
Dissertations, Theses, and Capstone Projects
Cocaine addiction is a serious public health hazard, and contributes to disastrous outcomes for individuals who suffer from it. Addiction is accompanied by an inability to control one's own behavior, and a preoccupation with cocaine at the expense of other rewarding pursuits. Previous research has suggested that difficulties with executive function and reward processing may underlie these problems, but the extent to which each contributes to addiction severity, or how these two factors may interact, remains to be elucidated. By using event related potential (ERP) measures in combination with information about self-reported anhedonia over three experiments, we set out to …
