Early Life and Educational Background
Constantine Sedikides was born on September 24, 1958 in Katerini, Greece. He completed his Bachelor’s degree in 1982 at Aristotle University of Thessaloniki, Greece, majoring in psychology and philosophy. He received a Master’s degree in developmental psychology in 1984 from Fordham University, USA. He went on to gain a Master’s (1986) and a PhD (1988) degree in social psychology from The Ohio State University, USA, under the supervision of Thomas M. Ostrom. His master’s thesis examined status differences in intergroup perception, whereas his PhD thesis addressed construct accessibility effects in communication settings.
Constantine Sedikides served as an Assistant Professor at University of Wisconsin – Madison, USA, between 1988 and 1993. He moved on to University of North Carolina at Chapel Hill, USA, in 1993 as an Associate Professor and was promoted to Full Professor in 1997. In 1999, he relocated in England, to become the Director of the Center for Research on Self and Identity at University of Southampton, where he remains until present. He has approximately 400 publications, including 15 edited volumes. His publications have appeared in such outlets as European Journal of Personality, Journal of Personality, Journal of Personality and Social Psychology, Journal of Research in Personality, and Social Psychological and Personality Science. He has been a co-editor of Psychological Inquiry and has served on the panel of several funding bodies. His research has been supported by grants from the British Academy, Economic and Social Research Council, National Institute of Health, The Leverhulme Trust, and Templeton Foundation (among others). He has received many awards, such as Award for Distinguished Contribution to Social Psychology (The British Psychological Society, 2018), Distinguished Lifetime Career Award (International Society for Self and Identity, 2017), The Presidents’ Award for Distinguished Contributions to Psychological Knowledge (The British Psychological Society, 2012), and Kurt Lewin Medal for Outstanding Scientific Contribution (European Association of Social Psychology, 2011).
Constantine Sedikides’ research is on self and identity (including narcissism) and their interplay with emotion and motivation, close relationships, and group or organizational processes. For example, one research program has addressed the determinants, consequences, and personality correlates (e.g., narcissism) of self-enhancement, the proclivity to hold an unduly positive image of one’s self. Another research program has examined the triggers, functions, and personality correlates of the emotion of nostalgia, a sentimental longing about one’s past. Finally, a third research program has looked into the situational instigators, health outcomes, and personality correlates, of state authenticity, the perception of one’s self as true or real.
