Explanation:

The Three Need Theory or Learned Theory was developed by David McClelland in the 1960s. The theory of needs suggests that an individual's needs are met and fulfilled over some time and gets molded through experiences. He has defined three needs in this theory namely Need for Achievement, Needs for power, and Need for Affiliation.

The Need for Achievement suggests that motivations are driven with the purpose to achieve something. For example, a student who wants to score the first rank in the class is driven with the need for achievement.

The Need for Power is the second need in the needs theory. This suggests that a person's motivation is driven sometimes with a need to control people or have authority. These needs desire to control the decisions of others according to their desire.

The Need for Affiliation is the third and the last in the needs theory. This implies an urge to build interpersonal and social relationships; and the need to feel accepted in society.
