Mental Fatigue: Examining Cognitive Performance And Driving Behavior In Young Adults, Abigail F. Helm
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
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
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, …
Efficacy Of Short-Term Emotional Regulation Training On Interference During Cognitive Tasks, Kerry Margaret Cannity
Efficacy Of Short-Term Emotional Regulation Training On Interference During Cognitive Tasks, Kerry Margaret Cannity
Doctoral Dissertations
The experience of emotion and attempts to regulate it are universal human phenomena. Emotion regulation is used to alter the affective intensity or tone, behaviors, and consequences associated with an emotional experience. This study examined how two common emotional regulation strategies (mindfulness and distraction) affect attentional performance following a negative mood induction via film. While previous literature has compared emotional regulation strategies’ effects on a variety of outcomes, the efficacy of these strategies to reduce cognitive interference caused by negative mood has not been examined. Both mindfulness and distraction are hypothesized to occur through the Attention Deployment mechanism of the …
The Cognitive Effects Of Light Color Temperature, Lauren Hartstein
The Cognitive Effects Of Light Color Temperature, Lauren Hartstein
Doctoral Dissertations
The goal of the current studies is to explore the conditions by which light color temperature impacts cognitive abilities and the development of this relationship. Experiments 1 and 1A explored whether exposure to light fluctuating around a central color temperature leads to increases in attention in adult participants. Results showed that, under the dynamic lighting condition, participants’ showed a significant decrease in reaction time on a measure of sustained attention, beyond those of a static light source at a cooler color temperature. Experiment 2 tested whether preschool-aged and 7-year-old participants would show increases in attention and cognitive flexibility after exposure …
Effect Of Mindfulness Training On Interpretation Exam Performance In Graduate Students In Interpreting, Julie E. Johnson
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, …
Objectively Measuring The Effects Of Sleep On Reading Comprehension And Sustained Selective Attention, Jennifer L. Thibodeaux
Objectively Measuring The Effects Of Sleep On Reading Comprehension And Sustained Selective Attention, Jennifer L. Thibodeaux
Doctoral Dissertations
The overall performance of a university is measured by retention rates of students. Because individuals who achieve lower grade point averages are at a higher risk of failing or dropping out of college, the academic performance of undergraduates should be the target of concern to maintain good retention rates. Academic performance, which is associated with attention and reading comprehension abilities, is affected by the sleep behavior of students. In regards to college students and sleep, research has indicated that college students demonstrate habitually poor sleep habits. Poor sleep habits have been linked to impaired attention and concentration abilities, but the …
