Albert Bandura was a renowned Canadian-American psychologist known for his contributions to social learning theory. He is considered the "Father of Social Learning Theory". Some of his major contributions include demonstrating through his famous "Bobo doll" studies that observational learning and modeling are important ways people learn new behaviors and information. He emphasized that intrinsic reinforcement and mental states also influence learning separate from external rewards.
