The Relationship Between Vagal Tone, A Marker Of Parasympathetic Activity, And Pro-Social Behavior, Emily A. Goodlin
The Relationship Between Vagal Tone, A Marker Of Parasympathetic Activity, And Pro-Social Behavior, Emily A. Goodlin
Scripps Senior Theses
Vagal tone, a measure of parasympathetic activity via the vagus nerve, is known to be associated with positive emotion because it promotes social engagement and self-soothing behavior. Heart rate variability (HRV), especially high frequency oscillation, is a direct measure of vagal tone, and has been used in previous studies to test the correlation between vagal tone and positive emotion. This study aims to determine if the two major oscillations of heart rate variability, high frequency (HF-HRV) and low frequency (LF-HRV) can predict pro-social behavior, which is classified as giving donations to charities. Baseline LF- and HF-HRV levels were recorded, and …
Effect Of The Acute Stress Response On Foraging Behavior In Mountain White-Crowned Sparrows, Zonotrichia Leucophrys, Sarah C. Osborne
Effect Of The Acute Stress Response On Foraging Behavior In Mountain White-Crowned Sparrows, Zonotrichia Leucophrys, Sarah C. Osborne
Scripps Senior Theses
Free-living vertebrates likely encounter many stressors throughout their lifetime, from fighting off a predator to coping with unpredictable weather. As a result, vertebrates will mount an acute response to the stressors. Here, we outline previous research conducted in behavioral endocrinology and stress physiology as it relates to our research. We then discuss our study with white-crowned sparrows (Zonotrichia leucophrys) in Tioga Pass Meadow, in which we examined how the acute stress response affects foraging behavior 24 hours after a stressor. In birds that underwent a stress series, we found there to be a significant 57% decrease in foraging …
