A theory that suggests that behavior is learned in part by imitation, observation, beliefs, and expectations is .

Social cognitive theory.

Explanation:

The social cognitive or learning theory arises, by Albert Bandura, as a response to the explanation of the transition between behaviorism and cognitivism. Albert Bandura believes that human behavior should be described in terms of the reciprocal interaction between cognitive or personal, behavioral and environmental determinants. For cognitive social theory, an important part of behavior results from vicarious or imitation learning. However, thought is an active element in the construction of reality by the individual. Each one builds their individual reality from the interaction between the environment and cognition. In this sense, the information handled by the individual is extremely important when establishing their behavior patterns.
