Early in this century, most empirically oriented psychologists believed that all motivation was based in the physiology of a set of non-nervous system tissue needs. The theories of that era reflected this belief and used it in an attempt to explain an increasing number of phenomena.

Their physiological basis is less understood; and as concepts, these needs lend themselves more easily to psycho logical than to physiological...

Chapters cover implications for...
