Observational learning, also known as social learning theory, occurs when an observer's behavior changes after viewing a model's behavior. According to Bandura, most human behavior is learned through observation and modeling. Bandura's research, including the famous Bobo doll experiments, demonstrated that children will imitate both aggressive and non-aggressive behaviors depending on whether the model is rewarded or punished. Television and other media can also influence behavior through modeling, as children may mimic violent acts they observe on screen.
