Both Risk and Reward are Processed Differently in Decisions Made Under Stress

Years of research show that stress influences cognition. Most of this research has focused on how stress affects memory and the hippocampus. However, stress impacts other regions involved in cognitive and emotional processing, including the prefrontal cortex, striatum, and insula. New research examining how stress affects decision processes reveals two consistent findings. First, acute stress enhances selection of previously rewarding outcomes but impairs selection of previously negative outcomes, possibly due to stress-induced changes in dopamine in reward-processing brain regions. Second, stress amplifies gender differences in strategies during risky decisions, with males taking more risk and females less risk under stress. These gender differences in behavior are associated with differences in activity in the insula and dorsal striatum, brain regions involved in computing risk and preparing to take action.     

Mercy as a Public Virtue

James F. Keenan defines mercy as “the willingness to enter the chaos of another.” Mercy thus defined, he argues, is the distinctive characteristic of Christian morality. This essay asserts that mercy is, in fact, a public virtue, one that can be affirmed across a broad range of religious and moral traditions. As a public virtue, mercy ought to shape both affective and effective responses to the Syrian refugee crisis in the United States.
