Objectives. We sought to test the hypothesis that providing help to others predicts a reduced association between stress and mortality. Methods. We examined data from participants (n = 846) in a study in the Detroit, Michigan, area. Participants completed baseline interviews that assessed past-year stressful events and whether the participant had provided tangible assistance to friends …

Hancock*, P. A., &Weaver, J. L. (2005). On time distortion under stress. Theoretical issues in ergonomics science, 6(2), 193-211.
Under conditions of extreme and life-threatening stress, people often report distortions of time. These distortional experiences are critical since, axiomatically, they occur in circumstances where small variations in behavior can mean the difference between survival and extinction. The present work examines the spectrum of evidence concerning such phenomena including observations from real-world events such as …
Cahill, L., Gorski, L., &Le, K. (2003). Enhanced human memory consolidation with post-learning stress: interaction with the degree of arousal at encoding.
Abundant evidence indicates that endogenous stress hormones such as epinephrine and corticosterone modulate memory consolidation in animals. We recently provided the first demonstration that an endogenous stress hormone (epinephrine) can enhance human memory consolidation. However, these findings also suggested that post-learning stress hormone activation does not uniformly enhance memory for all recently acquired information; rather, …
Chrousos, G. P. (2009). Stress and disorders of the stress system. Nature reviews endocrinology, 5(7), 374.
All organisms must maintain a complex dynamic equilibrium, or homeostasis, which is constantly challenged by internal or external adverse forces termed stressors. Stress occurs when homeostasis is threatened or perceived to be so; homeostasis is re-established by various physiological and behavioral adaptive responses. Neuroendocrine hormones have major roles in the regulation of both basal homeostasis …
Crum, A. J., Salovey, P., & Achor, S. (2013). Rethinking stress: The role of mindsets in determining the stress response. Journal of Personality and Social Psychology, 104(4), 716-733.
This article describes 3 studies that explore the role of mindsets in the context of stress. In Study 1, we present data supporting the reliability and validity of an 8-item instrument, the Stress Mindset Measure (SMM), designed to assess the extent to which an individual believes that the effects of stress are either enhancing or …
Stutzer, A., &Frey, B. S. (2008). Stress that doesn& #39;t pay: The commuting paradox. Scandinavian Journal of Economics, 110(2), 339-366.
People spend a lot of time commuting and often find it a burden. According to standard economics, the burden of commuting is chosen when compensated either on the labor or on the housing market so that individuals’ utility is equalized. However, in a direct test of this strong notion of equilibrium with panel data, we …
Dhabhar, F. S., &Mcewen, B. S. (1997). Acute stress enhances while chronic stress suppresses cell-mediated immunityin vivo: A potential role for leukocyte trafficking.
Delayed type hypersensitivity (DTH) reactions are antigen-specific, cell-mediated immune responses which, depending on the antigen involved, mediate beneficial (resistance to viruses, bacteria, fungi, and certain tumors) or harmful (allergic dermatitis, autoimmunity) aspects of immune function. We have shown that acute stress administered immediately before antigenic challenge results in a significant enhancement of a skin DTH …
