The study of violence in mass media analyzes the degree of correlation between themes of violence in media sources with real-world aggression and violence over time. Many social scientists support the correlation, however, some scholars argue that media research has methodological problems and that findings are exaggerated. Other scholars have suggested that the correlation exists, but can be unconventional to the current public belief.

The Bobo doll experiment is the collective name for a series of experiments performed by psychologist Albert Bandura to test his social learning theory. Between 1961 and 1963, he studied children's behaviour after watching an adult model act aggressively towards a Bobo doll. The most notable variation of the experiment measured the children's behavior after seeing the adult model rewarded, punished, or experience no consequence for physically abusing the Bobo doll.
