Dr. Quigley’s work focuses on how bodily regulation and sensory signals from the body help a brain to create emotions, including the role of individual- and situation-level variation in emotional experience, and how emotional experience relates to behaviors, cognition, and health. She uses laboratory and ambulatory (daily life) measures to understand what factors explain the enormous variation (in physiological changes, brain activity or expressive behaviors) that scientists observe across emotion instances (both within and across people). She also assesses how ‘interoceptive sensitivity’ – a person’s ability to accurately detect information from the body’s interior – can be used to better understand affect, a low-dimensional description of feelings (e.g., how activated or calm; how positive or negative). Other studies focus on how interoceptive sense data may help to integrate functions across bodily systems, e.g., how do oscillatory cardiac and respiratory signals influence vision? Other work examines physical symptoms, including how they vary with changes in internal bodily states, and how they change before and after a major life stressor, such as a terrorism event or a military deployment. Finally, Dr. Quigley uses technology-based interventions that incorporate person-specific data to enhance motivation to improve sleep, reduce pain, and decrease unhealthy behaviors such as smoking, especially in those with poor mental or physical health.
