Murray's system of needs

Murray's system of needs is a theory of motivation. In 1938 Henry Murray published Explorations in Personality, his system describing personality in terms of needs. For Murray, human nature involved a set of universal basic needs, with individual differences on these needs leading to the uniqueness of personality through varying dispositional tendencies for each need. In other words, specific needs are more important to some than to others. Frustration of these psychogenic (or psychological) needs plays a central role in the origin of psychological pain.

Murray differentiated each need as unique, but recognised commonalities among the needs. Behaviors may meet more than one need: for instance, performing a difficult task for your fraternity may meet the needs of both achievement and affiliation.
