Judith V. Torney-Purta, recipient of the Award for Distinguished Contributions to the International Advancement of Psychology, is cited for leadership of rigorous research on the development of democratic attitudes and civic knowledge among adolescents from more than 30 countries that has served as a catalyst for education and youth policy reform. Torney-Purta led research projects that are prime examples of international collaboration. She drew on these experiences in contributing to an initiative on international collaboration among behavioral and social scientists sponsored by the U.S. National Committee for the International Union of Psychological Science. Along with the citation, a biography and selected bibliography of Torney-Purta's works are presented. Also included is her paper, entitled "International psychological research that matters for policy and practice," a version of which she presented at the American Psychological Association's annual convention.
