Mental Fatigue: Examining Cognitive Performance And Driving Behavior In Young Adults, Abigail F. Helm Apr 2021

Mental Fatigue: Examining Cognitive Performance And Driving Behavior In Young Adults, Abigail F. Helm

Doctoral Dissertations

Mental fatigue causes an increase in task-based EEG theta and alpha power and a decrease in performance (for a review, see Tran et al., 2020). However, little is known about the emergence of mental fatigue in resting state EEG recordings and whether the progression of mental fatigue over time is influenced by individual differences. The current dissertation examined the utility of resting state EEG as a measure of mental fatigue by testing whether EEG power changed in young adults over the course of a cognitively demanding battery of tasks. The current dissertation also tested how this measure of mental fatigue …


Neural Correlates Of Individuation And Subordinate-Level Categorization Of Other-Race Faces In Infancy, Kelly Roth Dec 2020

Neural Correlates Of Individuation And Subordinate-Level Categorization Of Other-Race Faces In Infancy, Kelly Roth

Doctoral Dissertations

Perceptual narrowing is a domain-general process in which infants move from a broad sensitivity to a wide range of stimuli to developing expertise within often experienced native stimuli (Maurer & Werker, 2014). One outcome of this is the own-race bias, characterized by an increasing difficulty in discriminating other-race faces with age and experience for those raised in a racially homogenous environment (Anzures, Quinn, Pascalis, Slater, Tanaka, & Lee, 2013). Recent theorists have proposed that this is due to a categorization-individuation process, wherein infants begin to categorize non-native stimuli, such as other-species’ faces, but individuate native stimuli, such as often-experienced human …


Hearing And Seeing A Speaker: How Perceptual And Cognitive Factors Modulate The Dynamics Of Audiovisual Speech Perception, Elina Kaplan Oct 2018

Hearing And Seeing A Speaker: How Perceptual And Cognitive Factors Modulate The Dynamics Of Audiovisual Speech Perception, Elina Kaplan

Doctoral Dissertations

In face-to-face conversations, listeners process and combine speech information obtained from hearing and seeing the speaker talk. Audiovisual speech typically leads to more robust recognition of speech, as it provides more information for recognition but also as it helps listeners adjust to speaker idiosyncrasies. The goal of the current thesis was to examine how certain perceptual and cognitive factors modulate how listeners use visual speech to facilitate momentary speech perception and to adjust to a speaker’s idiosyncrasies. Results showed that (older) listeners’ sensitivity to cross-modal synchrony is related to the size of the audiovisual interactions during early perceptual processing. Furthermore, …


Effect Of Mindfulness Training On Interpretation Exam Performance In Graduate Students In Interpreting, Julie E. Johnson Jan 2016

Effect Of Mindfulness Training On Interpretation Exam Performance In Graduate Students In Interpreting, Julie E. Johnson

Doctoral Dissertations

Many graduate interpreting students struggle because the real-time, interactive nature of interpreting dictates that they be able to regulate their attention across different parallel cognitive activities and manage the inherent stress and unpredictability of the task. Within the framework of Cognitive Load Theory, this mixed-methods study explored the effect of short-term mindfulness training on consecutive interpreting exam performance using a quasi-experimental repeated-measures design. It also examined the relationships among mindfulness, stress, aspects of attention, and interpreting exam performance. The sample included 67 students (age M = 26.9 years; 82% female) across seven language programs (Chinese, French, German, Japanese, Korean, Russian, …
