Prof. ÇiÄŸdem BaÄŸcı
I am a Professor of social psychology at Sabancı University, Faculty of Arts and Social Sciences. After completing my BSc degree in psychology at Bogaziçi University, I continued my academic career at the University of Surrey (MSc in Research Methods) and at Goldsmiths, University of London (PhD) in United Kingdom.
I like to conduct both theoretical and applied research in the field of intragroup and intergroup relationships. I am interested in exploring relationships between various intergroup processes among both majority and minority group status children and adults. My main research areas include intergroup contact and cross-group friendships, prejudice and discrimination, social identity, and psychological well-being.
Recently, I have been working on various projects with international collaborators, including collective narcissism among minority group members, collective ownership threat, and social identity processes in vegetarianism.
