Albert Bandura developed social cognitive theory, which posits that people learn through observation of others. According to the theory, there are four steps to learning a new behavior: attention, retention, reproduction, and motivation. People pay attention to a modeled behavior, remember it, practice reproducing it, and are more likely to imitate behaviors that are reinforced. Bandura demonstrated this theory through studies showing people imitating behaviors they observed in videos, even violent scenes. Social cognitive theory also involves concepts like imagery, self-efficacy, and self-regulation, in which people observe and evaluate their own behaviors. The theory can be demonstrated both with and without technology, such as showing behavior models via video or observing the behaviors of classmates.
