Ruthie Pliskin - Research

My central areas of interest are intergroup relations, emotions and their regulation, and political psychology, with a focus on ideology and polarization. I am also interested in the psychology of intergroup hostility and conflict, in social change and collective action, and in psychological approaches to overcoming barriers to intergroup conflict resolution. I test these relationships both in the field and in the lab, employing a wide range of methods such as behavioral experiments, experience sampling, and surveys.

Since 2017, I have been an Assistant Professor (UD1) of Social, Economic and Organisational Psychology at Leiden University, where I also serve as co-chair of the Psychology Research Ethics Committee. Previously, I was a Postdoctoral Associate at New York University’s Department of Psychology, working with John Jost to examine ideological differences in processes of emotion regulation in various domains. My doctoral research examined “The Interrelations of Emotion and Ideology in Intergroup Conflict” at Tel Aviv University and the Interdisciplinary Center Herzliya, under the guidance of Eran Halperin, Daniel Bar-Tal, and Gal Sheppes. My research has been published in leading journals such as PNAS, Nature Communication, Emotion, Personality and Social Psychology Bulletin, the Journal of Experimental Social Psychology, and more. I have presented my research at numerous professional conferences, including the general meetings of the Society for Personality and Social Psychology, the European Association for Social Psychology, the International Society of Political Psychology, and the International Society for Research on Emotion, and have been invited to give talks in universities across the world.
