Self-Referential Processing: An Investigation Of The Mediating Role Of Alpha Power, Tanaz Javan
Self-Referential Processing: An Investigation Of The Mediating Role Of Alpha Power, Tanaz Javan
Electronic Thesis and Dissertation Repository
The EEG correlates of valenced self- and other-referential processing (SRP-ORP) are relatively little understood. This study examined the immediate effects of mindfulness meditation (MM) and EEG alpha neurofeedback (NFB) on resting state EEG alpha amplitudes and alpha event related (de-)synchronization (ERD/S) during an experimental implicit and explicit SRP-ORP task. Undergraduate students (n = 93) were randomized to a single session of MM, NFB alpha synchronization training (“alpha-up”), NFB alpha desynchronization training (“alpha-down”), or sham (placebo control) NFB before completing the Visual-Verbal Self-Other Referential Processing Task (VV-SORP-T). A reduction in resting-state alpha power over posterior cortex was observed across groups relative …
Associations Between Hypothalamic-Pituitary-Adrenal Axis System Gene Variants And Cortisol Reactivity In Preschoolers: Main Effects And Gene-Environment Interactions, Haroon I. Sheikh
Electronic Thesis and Dissertation Repository
Exposure to stressful events during early development has consistently been shown to produce long lasting effects on the hypothalamic-pituitary-adrenal (HPA) axis, which may increase vulnerability to mood and anxiety disorders. Recently reported genetic association studies indicate that these disorders may be influenced, in part, by gene-environment interactions (GxE) involving polymorphisms within the corticotrophin-releasing hormone and monoaminergic system genes. However, little is known about how genetic variants and life stress work to shape children’s neuroendocrine reactivity and emerging symptoms. Therefore, the aim of this thesis is to examine main effects of candidate genes and GxE on the neuroendocrine stress response and …
The Interaction Between Spatial Working And Reference Memory In Rats On A Radial Maze, Nicole Ann Guitar
The Interaction Between Spatial Working And Reference Memory In Rats On A Radial Maze, Nicole Ann Guitar
Undergraduate Honors Theses
The present study investigated the interaction between working and reference spatial memory in an effort to develop an animal model of this interaction. Twelve male Long-Evans rats were tested on an eight-arm radial maze in a two-phase procedure. In the study phase, a rat was allowed to enter four randomly selected arms for a food reward placed at the end of each arm. The test phase allowed the rat access to all eight arms, but only the previously unentered arms contained food. Two of the correct test arms were defined as reference memory arms because they were always correct. The …
Independent Component Analysis Of Self-Referential Processing In Women With Posttraumatic Stress Disorder, Elizabeth Thornley
Independent Component Analysis Of Self-Referential Processing In Women With Posttraumatic Stress Disorder, Elizabeth Thornley
Undergraduate Honors Theses
Posttraumatic stress disorder (PTSD) is a condition than can develop after exposure, or repeated exposure, to a traumatic event. Recent changes to the diagnostic criteria for PTSD reflect a new emphasis on the dysregulation of emotions related to self-appraisal and self-referential processing (SRP). SRP concerns stimuli that are experienced as strongly related to one’s own person and can be measured using valenced stimuli that relate to the participant’s concept of self. These paradigms are referred to as self- referential processing tasks. The current study used data from functional magnetic resonance imaging (fMRI) to investigate the activation of brain areas related …
