Motivation Predicts Self-Control Of Racial Bias After Viewing Alcohol Advertisements, Zachary Wolfgang Petzel
Motivation Predicts Self-Control Of Racial Bias After Viewing Alcohol Advertisements, Zachary Wolfgang Petzel
Dissertations
Exerting self-control shifts motivation toward rewarding cues (i.e., approach motivation) and impairs control of racial bias. However, whether approach motivation predicts deficits in control of racial bias is unknown. Exertion of self-control is also related to alcohol use, but whether exerting self-control shifts motivation toward alcohol-related cues is not established. Similar to exerting self-control, viewing alcohol-related cues shifts motivation and promotes racial bias. The current study examined the interaction between exerting self-control and viewing alcohol-related cues on approach motivation and its influence on racial bias. Participants (N = 71) exerted (or did not exert) self-control and then viewed neutral …
Electrophysiological Biomarkers Of Chemotherapy-Related Cognitive Impairment In Hematological Malignancy Patients, David E. Anderson
Electrophysiological Biomarkers Of Chemotherapy-Related Cognitive Impairment In Hematological Malignancy Patients, David E. Anderson
Theses & Dissertations
Multiple cancer populations frequently report cognitive impairment following treatment with chemotherapy agents (“chemo-brain”). Impaired neuropsychological performance is commonly reported in cognitive domains of attention and executive function. Understanding neural mechanisms underlying cognitive impairments is essential to developing prevention and rehabilitation strategies. Brain imaging studies frequently show chemotherapy-related impairments within the attentional control network, which is comprised of a constellation of cortical regions that govern reportedly impaired cognitive functions. In the current dissertation research, I developed a novel electrophysiology battery aimed at recording near-instantaneous neural activity within the attentional control network during cognitive task performance. Cancer patients diagnosed with hematological malignancy …

Towards Improving Learning With Consumer-Grade, Closed-Loop, Electroencephalographic Neurofeedback, Zall Soren Hirschstein
Senior Projects Spring 2018
Learning is an enigmatic process composed of a multitude of cognitive systems that are functionally and neuroanatomically distinct. Nevertheless, two undeniable pillars which underpin learning are attention and memory; to learn, one must attend, and maintain a representation of, an event. Psychological and neuroscientific technologies that permit researchers to “mind-read” have revealed much about the dynamics of these distinct processes that contribute to learning. This investigation first outlines the cognitive pillars which support learning and the technologies that permit such an understanding. It then employs a novel task—the amSMART paradigm—with the goal of building a real-time, closed-loop, electroencephalographic (EEG) neurofeedback …

Neuroimaging-based investigations of change blindness, a phenomenon in which seemingly obvious changes in visual scenes fail to be detected, have significantly advanced our understanding of visual awareness. The vast majority of prior investigations, however, utilize paradigms involving visual disruptions (e.g., intervening blank screens, saccadic movements, “mudsplashes”), making it difficult to isolate neural responses toward visual changes cleanly. To address this issue in this present study, high-density EEG data (256 channel) were collected from 25 participants using a paradigm in which visual changes were progressively introduced into detailed real-world scenes without the use of visual disruption. Oscillatory activity associated with undetected …
