Article
Full-text available
Cardiovascular reactions to acute psychological stress have been associated with cognitive function. However, previous work has assessed cardiovascular reactions and cognitive function in the laboratory at the same time. The present study examined the association between cardiovascular reactions to acute psychological stress in the laboratory and a...
Article
Adverse childhood experiences (ACEs) are robustly associated with later cardiovascular disease. Alterations in cardiovascular responses to stress may be an underlying mechanism. The present study examined whether ACEs predicted habituation of cardiovascular responses across two acute laboratory stress tasks, and whether this differed between men an...
Article
Preliminary prospective research suggests emotion dysregulation may confer vulnerability to poor stress responses. The present prospective study extends this research by examining both specific emotion regulation strategies and global emotion regulation difficulties in the context of acute stress following onset of the COVID-19 global pandemic in 1...
Article
Neuroticism has been associated with adverse cardiovascular health. Adverse cardiovascular health outcomes have also been linked to cardiovascular reactivity and cardiovascular reactivity habituation to acute psychosocial stress. As such, cardiovascular stress reactivity and habituation may be a factor in the association between neuroticism and dis...
Article
Background: Poor emotion regulation is associated with post-traumatic stress symptoms (PTSS). However, limited prospective research prevents any directional conclusions. No known studies have assessed emotion regulation with PTSS in American Indians, a high-risk population for poor mental health outcomes. The present prospective study explored whe...
Article
Positive affect is associated with more adaptive responses to psychological stress. However, few studies have examined the association between gratitude, a specific type of positive affect, with physiological responses to acute psychological stress. The current study aimed to replicate and extend on previous work examining the associations between...
Article
Psychological stress is a risk factor for cardiovascular disease. Individual differences in cardiovascular responses to stress may be an underlying mechanism. The literature examining the relationships between frequency and perceptions of life stress with cardiovascular reactivity to acute stress in the laboratory is inconclusive. Recent work highl...
Article
Hostility is associated with increased risk for cardiovascular disease. Heightened cardiovascular reactivity to psychological stress has been proposed as a potential mechanism. Recent work has emphasized a need to measure cardiovascular reactivity across multiple stress exposures to assess potential habituation over time. The aims of the current st...
Article
Objective: Increased autonomic arousal is a proposed risk factor for post-traumatic stress disorder (PTSD). Few studies have prospectively examined the association between physiological responses to acute psychological stress prior to a traumatic event with later PTSD symptoms. The present prospective study examined whether cardiovascular response...
Article
Full-text available
Friends share positive events with each other, and the perception of the responses as active and constructive (i.e., enthusiastic) is related to happiness. Two studies (N = 685) investigated friendship maintenance (FM) in same-sex best friendships as the mediator of the relationship between perceived responses to capitalization attempts (PRCA) and...
Presentation
Modern life on college campuses brings on relatively new relationships that challenge the traditional understanding of friendship. One of the new but increasingly popular type of relationship is friends with benefits relationships (FWBR). Although past research has identified predictors and types of FWBR, our knowledge about whether relationship ex...
