For the sake of this thesis, two scholarly collections edited by Dr. Robin S. Rosenberg – Our Superheroes, Ourselves (2013) and The Psychology of Superheroes: An Unauthorized Exploration (2008) – were reviewed. From these two collections and the multitude of psychological theories they cite, those most relevant to adolescent character development are considered. Three broad theories are examined first: positive psychology, equity theory, and attachment style. Then, six additional specific theories that define temperament (behavioral activation system and behavioral inhibition system), personality theory, duel identity, media identification, parasocial interaction, and comparison theory are reviewed. After reviewing each theory, Heroes in Crisis (2019) , a recent bestselling DC offering that addresses superhero trauma, is analyzed through the lens of these psychological theories in order to provide insight into the psychology or both superheroes and their adolescent fans.
