The International Convention of Psychological Science (ICPS) was the culmination of efforts by the Association for Psychological Science (APS) and an international network of organizations and individual scientists to stimulate scientific advances that are integrative; that is, in which investigators attack scientific problems by drawing broadly on research conducted at multiple levels of analysis and in multiple branches of psychological science, the cognitive sciences, the neurosciences, and related disciplines, including biology, economics, anthropology, and many others. ICPS was designed to surmount artificial disciplinary boundaries that can impede scientific progress and to highlight areas of investigation in which those boundaries have already been overcome.
