Alan Page Fiske
Alan Page Fiske is a psychological anthropologist studying how natural selection, neurobiology, ontogeny, psychology, and culture jointly shape human sociality. His research aims to understand what enables humans to coordinate in often cooperative, complex, culturally and historically varying systems of social relations. Fiske studies social and moral cognition, motives and emotion; relationship-constitutive actions, experiences, and communications; motivations for violence; interpretations of misfortune and death; and links between psychopathology and social relationships.
