Peggy Mycek Zoccola
My research integrates psychological and biological levels of analysis by applying social and emotional theories to the context of stress and health. Specifically, I focus on how cognitive processes such as rumination may influence physiological stress responses and sleep—two major health-relevant processes associated with morbidity and well-being. My work also aims to identify individual- and situation-level characteristics that may promote or prevent perseverative cognition (e.g., worry or rumination) and prolong physiological responses. For example, are some individuals predisposed to ruminate in response to stressors? Or, are certain types of stressors more likely to elicit rumination?
