I study the psychology of threat, with particular emphasis on the pathways by which threat-perception influences prejudice and aggression. Current studies focus on i) the neural mechanisms by which threat intensifies ethnocentrism, and ii) the cognitive representation of threat via conceptual metaphors of bodily size and muscularity. In related work, I examine factors that lead people to morally justify inflicting harm and the role of positive emotions (e.g., parental love) in defensive aggression.
