An international contingent of scholars gathered at the Annenberg Public Policy Center (APPC) this week for a two-day conference on the role of attitudes in policy, science communication, education, and other fields. Their work will be presented in a second edition of “The Handbook of Attitudes,” updating and expanding upon the original 2005 publication. The new edition of the handbook will include two volumes, one focusing on the theoretical side of attitudes and one on the real-world applications of attitudes research, including new work on the role of attitudes in such diverse fields as cancer, HIV, dieting behavior, advertising, accounting, violence, environmental issues, science communication, and migration. The Attitudes Conference was organized by Dolores Albarracín, of the University of Illinois (and formerly of the Annenberg School for Communication at Penn) and Blair T. Johnson, of the University of Connecticut, along with APPC director Kathleen Hall Jamieson. On the first day of the conference, authors briefed the group on their individual research, while the second day was devoted to discussion of overarching themes and an agenda for future research.
