Bandura, Ross & Ross (1961)
The study by Albert Bandura, Dorothea Ross, and Sheila Ross in 1961 is commonly known as the Bobo doll experiment. In this influential study, they investigated observational learning and aggression in children. Children who observed adults displaying aggressive behaviour toward a Bobo doll (an inflatable doll) were more likely to imitate the aggressive actions when given the opportunity. This experiment played a crucial role in the development of social learning theory, emphasizing the importance of observational learning, modeling, and the influence of the social environment on behaviour.
