Henry Murray’s Theory of Motivation Murray like Maslow also propounded the theory of motivation. He divided his theory into two, viscerogenic and psychogenic needs. 1. Viscerogenic Needs These are referred to as biological or physiological needs. They are the primary needs and these include the desire for water, sex, sleep, food, air and excretion of waste products. They are the higher order needs. 2. Psychogenic Needs These needs correspond with other needs in Maslow’s theory. They are secondary needs. Examples of these are the longing for safety and security, love and comradeship, self- esteem, beautiful things or serene environment, rare or dominant positions etc.
