The Carol and Ed Diener Award in Social Psychology, awarded by the Society of Personality and Social Psychology, is designed to recognize a mid-career scholar whose work has added substantially to the body of knowledge to the social psychology field and/or brings together personality psychology and social psychology. Carol and Ed Diener spent much of their careers here in the Department of Psychology at the University of Illinois Urbana-Champaign, and so it is especially gratifying that one of current faculty should receive this award.
