This dissertation proposes a novel definition of anonymity, drawing on past definitions as well as psychological theory, to propose that pseudonymous identities can have a complex and nuanced influence in emphasizing certain personality traits when used in online discussion. This dissertation connects this definition to the Proteus Effect — the observation that individuals adopt behavior stereotypical of the avatars they use in virtual worlds (Yee & Bailenson, 2007) — to test how the presence and character of avatars in an online instant messenger influences aggression during political discussions. A 2x2 factorial experiment is used to evaluate participant aggression following small group deliberations between groups of participants assigned aggressive and unaggressive usernames and avatars, as well as accounts displaying an avatar and username vs only a username. A follow-up online experiment is used to show that similar effects of identity on behavior can be achieved simply by assigning participants to participate in similar tasks as moderators or as themselves.
