Motivation refers to the inner strivings of individuals that direct their behavior. It involves the psychological forces that drive individuals to act in a particular way to achieve certain goals or gratifications.
A norm represents a rule or standard that is considered acceptable behavior within a group or society and, in psychology, refers to the average standard of achievement on a test for a selected group.
A self-fulfilling prophecy is a prediction that causes itself to become true due to the behavior it inspires in people. For instance, believing that a political candidate will win an election may encourage enough people to vote, thus enabling the candidate's victory.
