A published database of presentations from the seven most recent International Congresses of Applied Psychology (ICAPs) was compared to a similar but unpublished database (Adair, Anguas-Plata, Unik, Radons, 2009) on the International Congresses of Psychology (ICPs) for the years 1996-2004. Analyses revealed phenomena characteristic of attendance at both international congresses: Participation rates spike dramatically for host countries; less dramatic regional surges in participation occur when the congress is held in a neighbouring country. Psychologists from 117 different countries participated in the seven recent congresses (ICAP and ICP) from 1994 to 2006. Overall ICP was double the size of ICAP, and represented a larger set of countries at each of its congresses. Regardless of location, most participants at both congresses came from the same 11 economically advantaged and seven majority-world countries. Congress presentations are dispersed across a much larger number of countries than are journal publications. The USA, for example, had modest 14.4% (ICAP) and 11.6% (ICP) presentation rates, much smaller than its majority share of publications (Adair, 2009). By contrast, the USA had the greater share of invited addresses at both ICAP (33.7%) and ICP (28.9%) congresses. Nonetheless, the majority-world countries contributing to both ICAP and ICP are clearly indicative of where the discipline is gaining strength and importance to international psychology. The emergence of Iran as a new leading national contributor to the two most recent international congresses, and the rise in the proportion of presentations by majority-world psychologists at ICAPs from only about one in five to more than one of every three presentations in recent congresses are findings consistent with Zakaria's (2008) analysis of changes taking place in the world. Within international congresses, certainly, the orise of the resto is changing the face of international psychology.
