Explain any three assumptions of Maslow's need hierarchy theory.

Abraham Maslow gave a theory, based on human needs. He felt that within every human being, there exists a hierarchy of five needs. His theory is based on certain assumptions which are as follows:

(i) He believed that human behaviour is based on their needs. Satisfaction of such needs influences their behaviour. When one need is satisfied, they will move to strive for other needs.

(ii) A satisfied need can no longer motivate a person to work, only next higher level need can motivate him.

(iii) A person moves to the next higher level of the hierarchy only when the lower need is satisfied.
