In recent years, as science becomes increasingly international and collaborative, the importance of projects that involve research teams and research subjects from different countries has grown markedly. Such teams often cross disciplinary, cultural, geographic and linguistic borders as well as national ones. Successfully planning and carrying out such efforts can result in substantial advantages for both science and scientists. The participating researchers, however, also face significant intellectual, bureaucratic, organizational and interpersonal challenges. Building Infrastructure for International Collaborative Research in the Social and Behavioral Sciences is the summary of a workshop convened by the National Research Council's Committee on International Collaborations in Social and Behavioral Sciences in September 2013 to identify ways to reduce impediments and to increase access to cross-national research collaborations among a broad range of American scholars in the behavioral and social sciences (and education), especially early career scholars. Over the course of two and a half days, individuals from universities and federal agencies, professional organizations, and other parties with interests in international collaboration in the behavior and social sciences and education made presentations and participated in discussions. They came from diverse fields including cognitive psychology, developmental psychology, comparative education, educational anthropology, sociology, organizational psychology, the health sciences, international development studies, higher education administration, and international exchange.
