SUMMARY:Sandeep Mishra - Minding the Gap: Inequality\, Socioemotional Comparisons\, and Risk-Sensitivity
DESCRIPTION:Sandeep Mishra: University of ReginaSubstantial epidemiological evidence shows that higher levels of income inequality are associated with a wide array of negative societal-level outcomes\, ranging from greater risk-taking and crime to poorer mental and physical health. However\, surprisingly little research has examined individual-level consequences of inequality. Risk-sensitivity theory\, developed in the field of behavioral ecology\, may help to shed light on why inequality has such wide-ranging harmful effects. Risk-sensitivity theory specifically posits that that risk-taking is a product of conditions of need (i.e.\, disparity between one’s present and desired/goal states). In this presentation\, I explore how risk-sensitivity can be applied to understanding risk-taking under conditions of inequality. I also address research suggesting that proximate-level emotional reactions to social comparisons and disparity can shed light on risk-sensitive decision-making specifically\, and mental health more generally.

SUMMARY:Joshua Ackerman - The Sick Sense: Sensory Detection of Infectious Disease
DESCRIPTION:Joshua Ackerman: University of MichiganFunctional psychological responses to the dangers of infectious disease first require perceiving that pathogenic threats exist. How do people detect such threats? One way is through use of conceptual knowledge from lay beliefs or direct communication\, but another\, perhaps more primitive\, means involves use of specific sensory information. In this talk\, I will review human and non-human evidence regarding detection of pathogen indicators\, focusing on various domains of sensory cues. I will also consider the relevance of this evidence for our understanding of downstream consequences that occur following detection. These sensory processes and downstream outcomes are marked by biases that drive behavior in particular\, often functional ways.

SUMMARY:Matthew Zefferman - The Evolutionary Origins of PTSD and Moral Injury: Evidence from a Small Scale Society.
DESCRIPTION:Matthew Zefferman: Arizona State UniversityCombat veterans in western industrialized societies can develop a collection of symptoms classified as post-traumatic stress disorder (PTSD). The origins of PTSD are a mystery. Some posit that it has deep evolutionary roots as a mechanism for avoiding and responding to harm. Others posit that it is socially constructed and perhaps unique to industrialized societies. I propose\, with a gene-culture co-evolutionary theory of combat stress\, that both perspectives are partially right and incomplete. This theory explains additional puzzling aspects of combat stress\, such as the origins of “moral injury.” I support this new theory with evidence from ethnographic research and interviews with Turkana warriors from northern Kenya.
