Role-playing method is not only an evaluation method that requires the subjects to play a specific management role to observe the various performances of the subjects and understand their psychological quality and potential ability, but also the most effective training method, which requires the subjects to play a specified behavioral role and evaluate and feedback their behavioral performance through scenario simulation, thus helping the subjects to develop and improve their behavioral skills. Role-playing theory is developed on the basis of Meade's role theory and Bandura's social learning theory.

Through the role-playing method, we can evaluate the behavior of the subjects in the scenario simulation, and evaluate their psychological quality and various potential abilities. It can measure the psychological quality of the subjects, such as personality, temperament, hobbies and so on. It can also measure the potential abilities of the subjects such as social judgment, decision-making ability and leadership ability.

American psychologist Bandura's social learning theory is also the theoretical basis for role-playing to shape people's behavior. According to the theory of social learning, people's social behavior is obtained through "observation learning".

Example, especially the behavior of respected figures, has an alternative reinforcing effect. Vicarious reinforcement is also a cognitive process, including observing and imitating the role model, that is, observing the behavior and results of the role model and understanding how to use this behavior. Under the influence of this alternative reinforcement, although no direct action is taken, it will produce a lot of behavioral results. This has been confirmed by a large number of experiments.

Therefore, giving people correct, beautiful and standardized behavioral stimuli from the front is conducive to people developing good habits and changing the role of bad behaviors.
