Bandura on the Sources of Aggression
According to Bandura (1986), the three main sources through which aggression is learned are:
Family influences: Children often learn aggressive behaviors by observing and imitating their parents, siblings, and others in their family.
Media influences: Exposure to violent media, such as television shows, movies, and video games, can contribute to aggressive thoughts and behaviors.
Observational learning: Through observing the behavior of others, individuals learn how to act aggressively or non-aggressively based on reinforcement and modeling.
These factors highlight the role of both social and cognitive processes in the acquisition of aggressive behaviors.
