Social cognitive theory proposes that observational learning, or learning from watching others, is an important mechanism by which people acquire and maintain behaviors. Psychologist Albert Bandura expanded on this idea and conducted seminal research, such as the Bobo doll experiment, demonstrating that observing models and the consequences of their behaviors can influence subsequent behaviors. According to Bandura, self-efficacy, or one's belief in their ability to perform a behavior, plays a central role in whether observational learning leads to behavioral change.
