Albert Bandura was a pioneering psychologist who developed social learning theory and the concept of observational learning. He proposed that people can learn new behaviors and information by watching others, either through direct experience or through various forms of media. Bandura identified four processes of observational learning: attention, retention, reproduction, and motivation. His famous Bobo doll experiments in the 1960s demonstrated that children's exposure to and imitation of aggressive behaviors could be influenced by observing and modeling adult behaviors. Bandura's social learning theory and concept of observational learning had significant impacts on the fields of education, parenting, advertising, and beyond.
