My research examines issues of identity including collective emotions, global citizenship, fanship, and responses to perceived copycatting. Collective emotions are emotions felt due to membership in a group. This research examines how collective emotions are associated with intergroup relations (e.g., threat to the group). My global citizenship research examines the antecedents and consequences of identifying the self as a global citizen, and how to foster a global citizen identity in the classroom. Additionally, I am examining the association between fans and fan groups, and have found that fans are alike regardless of what interest they pursue. My copycatting research focuses on the emotional, cognitive, and behavioral reactions to the intentional copying of public identity characteristics, and victims’ need to feel in control of their public identities.
