Past Visiting Scholars

David Butz

Morehead State University, United States

Dr. Butz examines the psychological factors that lead people to approach or avoid intergroup contact with a particular emphasis on understanding the causes of negative approach-related responses, such as intergroup anger, hostility, and blame. In collaboration with Dr. Tropp and researchers at Queens University, Belfast, he studies sources of avoidance and hostility in interactions between religious and political communities in Northern Ireland and approaches to promote trust between the communities.

Dr. Butz also examines environmental factors that enter into decisions to approach or avoid intergroup contact, focusing on the implications of identity cues and symbols for reducing intergroup conflict and improving the quality of intergroup relations. In future work he will be expanding upon his research by examining a variety of approaches to promote interest in intergroup contact and trust between groups. He is also planning on extending his work on identity symbols by considering the situations and motivations that lead people to display overt symbols of their identity. Dr. Butz has taken the position of Assistant Professor of Psychology at Morehead State University, Morehead, KY.

Pumla Gobodo-Madikizela

University of Capetown, South Africa

Pumla Gobodo-Madikizela is a Professor of Psychology at the University of Cape Town and award-winning author of the book, A Human Being Died That Night: A Story of Forgiveness.

She served on the Human Rights Violations Committee of the Truth and Reconciliation Commission (TRC), where her interest in the relationship between perpetrators' expressions of remorseful apologies and victims' response of forgiveness began. Since serving on the TRC, she has been engaged in the study of forgiveness in the aftermath of mass atrocity, with a focus on post-apartheid dialogue encounters between victim/survivors and perpetrators in the South African context.

This work has led to her current research, which examines the web of feelings, traumatic memories, guilt, and the transformative shifts that open up the possibility of empathy in the dialogue between victims and perpetrators after mass violence. Her other books include a co-authored publication, Narrating our Healing: Perspectives on Healing Trauma (2007) and Memory, Narrative and Forgiveness: Perspectives on Unfinished Journeys of the Past (co-editor, 2009).

Özden Melis Ulug

With a BSc major in Psychology and a BA minor in Studies in Politics from Middle East Technical University in Turkey, Melis received her MSc degree in Political Psychology with distinction from Queen’s University Belfast in Northern Ireland in 2011 and her PhD degree in Psychology from Jacobs University Bremen in Germany in 2016. She focused on the socially shared conflict understandings among different segments of society (e.g., politicians, scholars and journalists, and lay people) in the context of the Kurdish conflict in Turkey. She has also conducted follow-up studies in order to understand the role of intergroup contact in different status groups on conflict understandings and peace-related outcomes, such as attitudes toward reconciliation and peace.

In addition to intergroup conflict, reconciliation and peace, her research interests also include collective action and solidarity between disadvantaged groups. Melis has recently conducted both qualitative and quantitative studies on protestors’ motivations and their solidarity experiences in the context of Gezi Park protests in 2013 in Turkey. She expects to conduct more research on how disadvantaged groups such as women and Blacks experience contact with the advantaged groups in the context of protests and activism in the US.

Hanne Watkins

Hanne M. Watkins holds a BA (Hons.) in Psychology and Linguistics, and a Master’s degree in Clinical Psychology from the University of Melbourne, in Australia. She also completed her Ph.D. in Social Psychology at the University of Melbourne, in 2016. Her main research interests are moral psychology, intergroup conflict, and philosophical “just war theory,” which is why her thesis was on how people make moral judgments about killing in war.

However, moral psychology is a broad church, and for the past two years (2016 – 2018) she was a Postdoctoral Research Fellow at UPenn working with Geoff Goodwin on a project involving people who are exceptionally commitment to various environmental causes. Many of these “environmental exemplars” express a moral obligation to care for the natural environment and for future generations of humans. Through in depth interviews we attempted to unpack this sense of obligation, as well as explore how it relates to the environmentalists’ sense of connection to nature and to other people, and to their optimism (or pessimism) about the future of the planet.

As part of the Psychology of Peace and Violence Program at UMass, Hanne will continue to research both environmental and moral psychology, focusing first on how people conceptualize war and peace – Are the two concepts antonyms? Do they include moral content, good or bad? Are wars inevitably associated with environmental destruction as well as with the destruction of human life? – and the consequences these conceptualizations have for outcomes such as willingness to support specific peace building initiatives, engagement with veteran community groups, and the likelihood of joining the military.
