Representation Of Reward And Risk In The Brain’S Motor System: Studies In Adolescents And Adults, Xingjie Chen
Representation Of Reward And Risk In The Brain’S Motor System: Studies In Adolescents And Adults, Xingjie Chen
Doctoral Dissertations
In the neuroscience of economic decision making, the brain’s motor system has been ascribed a role in implementing choice actions. However, recent work has revealed canonical motor signals much in advance of choice action, possibly indicating their role in evaluation of decision options. In the current dissertation, we applied multimodal neuroimaging combining EEG and fMRI and used a novel paradigm that temporally separated the evaluation phase from the action phase of a decision-making process to investigate the mechanisms through which the motor control system contributes to decision making. Additionally, we further examined the developmental changes during the two phases of …
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 …
Experience With Difficult Target Discrimination Makes Search Less Efficient: An Analysis Using Eye Movements, Junha Chang
Experience With Difficult Target Discrimination Makes Search Less Efficient: An Analysis Using Eye Movements, Junha Chang
Doctoral Dissertations
Recent studies demonstrate that experience influences observers’ strategic attentional guidance in visual searches. The current study explored how experience with difficult target color discrimination influences search strategy. Two participant groups were compared through seven dual-target search experiments: A hard search experience group and an easy search experience group. The easy search experience group performed only the easy color discrimination trials in which the two targets were easily distinguishable from distractors in the color dimension. The hard search experience group performed the same easy discrimination trials in half of the trials. The other half were difficult color discrimination trials in which …
Investigating The Self-Efficacy Awareness Of Black Female Technology Leaders, Marie Roberts De La Parra
Investigating The Self-Efficacy Awareness Of Black Female Technology Leaders, Marie Roberts De La Parra
Doctoral Dissertations
Black female technology leaders lack leadership opportunities, which affects their self-efficacy and is a crucial concern. Self-efficacy is based on the concept that an individual’s belief in what they can achieve influences their actions and how much effort they invest in the selected action. Self-persuasion can provide high or low self-satisfaction as a determinant for creating incentives for success or failure and converting thoughts and emotions to actions. Limited research has investigated the mindset, the thought patterns, and the self-belief undertaken by Black females in the world of technology. Despite limited amounts of research, data suggest that Black female leaders …
