The Lifetrack tripod Model is More Succinct than Murray’s

Because the three-sphere model seeks to determine the essence of, rather than great detail about, human personality, it is more succinct than Murray’s 1938 lengthy list of more than 20 motives or needs.  Lifetrack groups all psychological needs in three primary spheres: self, intimacy and achievement. These needs can be just as important as biological needs and are not placed in a hierarchy.  They are not in a natural state of disequilibrium; they can co-exist in all healthy and distressed individuals.

To compare with Murray, the achievement sphere incorporates the need for power or control over the environment. Affiliation and nuturance fall into the intimacy sphere. Notably absent in Murray’s list is the self sphere.

Ik word een beetje iebel van 20 needs. Reiss doet het voor 16 needs:
