Drive-reduction theory

Explanation:

Drive-reduction theory: This is one of the theory of motivation which is developed by Clark L. Hull. The theory focuses on the process of motivation that originates from biological drives or needs. He suggested that an individual's behavior displays his or her inner desire to content his or her physical deficiencies.
