After obtaining his PhD in 1969 from the University of Louvain, Jacques-Philippe Leyens worked for 2 years with Leonard Berkowitz and Ross Parke at the University of Madison-Wisconsin. He returned to Louvain in 1971, where he has remained since then. Starting with the influence of violence in the mass media, his research interests extended to war traumas in Palestinian children, interpersonal perception, stereotyping, intergroup relations, and racism. His current main interests are the infrahumanization of outgroups and the differential impact of various norms of nondiscrimination. The last two streams of research question the conditions leading groups members to unconsciously think as themselves as more uniquely humans than outgroup members, and to use color-blind or color-conscious strategies to restore harmony between groups. Infrahumanization leads to construe a subjective reality, whose nature determines the success of one or the other norm of nondiscrimination.
He has served as chief editor of the European Journal of Social Psychology and as President of the European Association of Experimental Social Psychology. Among his awards, he is most proud of the First International Prize of Psychology from the Association of Portuguese Psychologists and the Tajfel Lecture Award.
