Henry A Murray

Henry A Murray focused on basic needs in personality which he called psychogenic needs. He believed these needs were largely at the unconscious level. After researching this area, he narrowed these needs down to 27, although the list and names vary depending on the time frame and the author.

Three of these, especially, have been the focus of study: the need for Power, Affiliation, and Achievement.
The need for Power refers to the desire or need to impact other people, to control or be in a position of influence. Careers that involve these aspects are better suited for high nPow people, such as teachers, psychologists, journalists, and supervisors. They don't necessarily make the best leaders though. Research has found that those with high nPow are more likely to rate an employee higher if that employee has a tendency to schmooz or flatter the subject where those with low or moderate nPow rate employees the same. In this sense, those with high nPow would do well if they also had traits of self-control and objectivity.

The need for affiliation has a long history of research, and studies show that those with a high nAff often have a larger social circle. They spend more time interacting with other such as talking on the phone and writing letters, and they are more likely to be members of social groups or clubs. Those with high nAff are also more likely to get lonely than those low in nAff, so their need for affiliation may be related to their sense of self and their desire for external stimulation.

Those with a high need for achievement (nAch) demonstrate a consistent concern about meeting obligations and accomplishing tasks. They are, however, more focused on internal motivation rather than external rewards. For example, those high in nAch are more likely to value intelligence and personal achievement over recognition and praise.
