Constantine Sedikides

Professor Constantine Sedikides is a faculty member in the Psychology Department at the University of Southampton, holding the position of Professor of Social and Personality Psychology. His research centers on self-evaluation processes and identity dynamics within social contexts.

His primary research interests include:

• Self-evaluation motives (self-enhancement, self-protection, self-improvement)
• Cultural influences on self-perception
• Narcissism and its subtypes
• Implicit/explicit self-protective strategies
• The self in relational and organizational contexts
• Nostalgia and authenticity mechanisms

As a member of the Centre for Research on Self and Identity, his work bridges theoretical frameworks with empirical investigations into human motivation.

Analysis of his 2025 publications reveals dominant trends in narcissism subtypes (particularly communal narcissism), nostalgia's role in emotional regulation and organizational behavior, and the interplay between self-integrity and authenticity. His research increasingly integrates cross-cultural perspectives with neuroaffective mechanisms, showing strong interdisciplinary connections between social psychology, organizational behavior, and cognitive neuroscience.

Professor Sedikides actively collaborates on major research projects including ESRC-funded work on identity change barriers and John Templeton Foundation research on intellectual arrogance, demonstrating sustained engagement with significant theoretical questions in personality science.
