For “Badges in Social Media: A Social Psychological Perspective” social psychologist/research scientist Judd Antin and Principal Research Scientist, Elizabeth Churchill collaborated to summarize what badges are in specific terms, and how they work in what they call the “5 Primary Functions for Achievements”. These include Goal Setting, Instruction, Reputation, Status/Affirmation and Group identification. They make mention that while badges strongly influence some users, some others are indifferent and in some cases even demotivated by the implementation of badges. The paper ends by concluding that more research needs to be done in different contexts to explore the circumstances in which badges are the most effective.
