Filter by:This study seeks to measure the time course of circulating proinflammatory markers (interleukin-1 beta [IL-1β], interleukin-6 [IL-6], tumor necrosis factor alpha [TNF-α], and C-reactive protein [CRP]) and salivary alpha amylase (sAA) following laboratory fear arousal. Further, this study seeks to implement neurocognitive, physiological, and self-report measures to explore the role of threat sensitivity as a predictor of this response. The broad research question seeks to better understand the relationship between neurocognitive fear and subsequent stress responding elicited by both the immune system (i.e., proinflammatory markers) and autonomic nervous system (i.e., sAA). In light of these aims, the primary outcomes of the current study are the proinflammatory markers (IL-1β, IL-6, TNF-α, CRP), while secondary outcomes consist of sAA, neurocognitive measures (i.e., dot-probe task), physiological correlates (i.e., heart rate, galvanic skin response), and self-report measures.
