Explanation:
In psychology there's a type of learning proposed by Psychologist Albert Bandura called "observational learning" that is a type of learning in which a person learns by observing the behavior of others.
This type of social learning can take diverse forms, but there is always three aspects that are present:
1- Observer.
2-Specific action.
3-A model doing the action.
