Geoffrey Leonardelli
I am interested how self-perception enhances human effectiveness, particularly in the domains of group processes and personal performance. My work on group processes examines questions about group identification, social stigma, decision-making, negotiations, and conflict in intergroup and intragroup settings. My work on personal performance examines how individuals' motivation, self-theories, and self-evaluations affect performance and negotiator success.
This research is programmatic and empirical, and I have tested predictions derived from optimal distinctiveness theory, inclusive fitness theory, social identity theory, self-categorization theory, the group engagement model, the self-protective properties of social stigma, regulatory focus theory, and research on implicit theories of intelligence, self-evaluation, behavioral economics, and intergroup contact.
