Influence Of Drd4 Receptor Gene Polymorphism On Aspirational Quality And Approach Motivation, Harry Henry-Ojo
Influence Of Drd4 Receptor Gene Polymorphism On Aspirational Quality And Approach Motivation, Harry Henry-Ojo
ATU Theses and Dissertations 2021 - Present
The present study investigates the presence of a molecular genetic basis of the quality of aspiration and motivation for behavior described by Ryan and Deci’s self-determination theory and Gray’s biopsychological theory of personality respectively. In this study, investigation was carried out to determine the impact of DRD4 receptor gene polymorphism on intrinsic and extrinsic aspiration as well as approach motivation using the Aspiration Index scales and Behavioral Inhibition and Activation (BIS/BAS) scales as our psychometric instrument of evaluation. In a pilot study consisting of 9 healthy subjects, the 7R allele of DRD4 receptor gene was associated with higher mean score …
Dissecting The Neural Circuits Mediating Pain-Induced Negative Affect And Drug-Seeking Behaviors, Tamara Markovic
Dissecting The Neural Circuits Mediating Pain-Induced Negative Affect And Drug-Seeking Behaviors, Tamara Markovic
Arts & Sciences Electronic Theses and Dissertations
Understating the function of neural circuits and the state-depended adaptations within them is one of the fundamental aims in the field of neuroscience. With recent technical developments in monitoring circuit dynamic, such as calcium (Ca2+) imaging, visualizing synaptic connections using viral approaches and manipulating neuronal activity in cell-specific manner such as optogenetic and chemogenetics, we are now able to mechanistically link the activity and function of neural circuits with behavioral outcomes.Using the above-mentioned techniques, I demonstrate that pain induces somatic adaptations in the Ventral Tegmental Area (VTA) dopamine (DA) neurons to drive anhedonia-like behaviors. Pain is a complex phenomenon composed …
Motivation To Persevere Among Nontraditional Black Online College Students, Alice Ginwright Sapp
Motivation To Persevere Among Nontraditional Black Online College Students, Alice Ginwright Sapp
Walden Dissertations and Doctoral Studies
There is limited research on grit among nontraditional online adult learners, especially focusing on male and female Black college students who are adult online learners, including those who are older than 40. The purpose of this quantitative quasi-experimental study was to examine possible between-group differences in motivation to persevere, as defined by grit, among nontraditional-age Black online college students. The theoretical framework for this study was life-span development theory and the grit motivational factor model. A sample of 138 Black male and female online, nontraditional-age college students completed an online survey. Demographic information was collected, and scores from the Short …
