Comparing Stress Responses In Generalized Anxiety Disorder Vs. Non-Clinical Populations: A Cortisol And Alpha-Amylase Study, Dominic Joseph Di Loreto
Comparing Stress Responses In Generalized Anxiety Disorder Vs. Non-Clinical Populations: A Cortisol And Alpha-Amylase Study, Dominic Joseph Di Loreto
Masters Theses
Debilitating anxiety affects 6.8 million Americans. Cortisol is an established measure of the stress response which reflects the hypothalamic-pituitary-adrenal (HPA) axis activity. However, salivary alpha-amylase (sAA) is a relatively new measure of the stress response, and it reflects the sympathetic-adrenal-medullary pathway (SAM pathway) activity. Our aim was to compare these two aspects of the stress response in a Generalized Anxiety Disorder (GAD) and a non-clinical population under a stressful stimulus (Knee replacement surgery video). To our knowledge this is the first time anyone has looked at both sAA and cortisol together with respect to GAD. We hypothesized that both cortisol …
Effects Of 5-Ht1a Receptors On The Development Of Stress-Induced Changes In Behavior, Lauren Renee Bader
Effects Of 5-Ht1a Receptors On The Development Of Stress-Induced Changes In Behavior, Lauren Renee Bader
Masters Theses
Social defeat leads to both increased anxiety-like behavior and the formation of a fear memory for a specific opponent. We have shown that serotonin (5-HT) signaling, particularly in the basolateral amygdala (BLA), alters the acquisition of the conditioned defeat response in Syrian hamsters. While activation of 5-HT1A receptors impairs the acquisition of conditioned defeat, it is unclear whether these receptors alter the development of anxiety-like behavior or formation of fear memories. One method for investigating the formation of defeat-induced fear memories is to measure avoidance of former opponents, and many researchers have reliably used the open field as a measure …
Do Dogs Increase Learning? The Effect Of Therapy Dogs On Academic Stress And Spanish Second Language Learning, Elaine Maralee Henry
Do Dogs Increase Learning? The Effect Of Therapy Dogs On Academic Stress And Spanish Second Language Learning, Elaine Maralee Henry
Masters Theses
Numerous physiological changes occur during periods of high stress and learning Spanish as a second language in a classroom setting may induce significant levels of academic stress. A possible solution is the use of therapy dogs in second language classes since therapy dogs are known to lower stress and improve physiological measures such as heart rate and blood pressure. Data were collected from 18 University of Tennessee-Knoxville juniors and seniors. A within subjects design required participants to listen to a short Spanish lesson during three conditions: baseline, therapy dog, and no therapy dog. In all conditions, saliva samples were collected …
