subdivided into three categories: the Need for Achievement, the Need for Affiliation, and the Need for Power. The Need for Achievement refers to the notion of getting ahead and succeeding. The Need for Affiliation is the desire to be around people and be well received socially. It also includes the desire for being a member in a group and conformity. The Need for Power is the desire for control over others and over yourself. It confers the need to be able to exercise direction in the world surrounding you, and cause things to happen. Individuals who have high needs for achievement will tend to engage in competitive activities in order to fulfill this desire. Individuals who need to feel affiliated will tend to join clubs, groups and teams to satiate that want. Individuals who have the need for power will seek activities which likewise satisfy this need, such as, running for high positions in organizations and seeking opportunities to exercise that dominance. This is not to say that one person cannot have needs spanning all three categories. A person may have the need for affiliation at the same time they have the need for power. While this may initially seem contradictory, there are instances where both needs can be fulfilled. Also, timing may connote different strengths of needs at different moments. So, while a person may strongly feel the need to affiliate during times of loneliness, they may at another time feel the strong need for power when instructed to organize an event. Needs may arise and change along with a change of context. Maslow's hierarchy of needs Content theory of human motivation includes both Abraham Maslow's hierarchy of needs and Herzberg's two-factor theory. Maslow's theory is one of the most widely discussed theories of motivation. Abraham Maslow believed that man is inherently good and argued that individuals possess a constantly growing inner drive that has great potential. The needs hierarchy system is a commonly used scheme for classifying human motives. The American motivation psychologist Abraham H. Maslow (1954) developed the hierarchy of needs consisting of five hierarchic classes. According to Maslow, people are motivated by unsatisfied needs. The needs, listed from basic (lowest-earliest) to most complex (highest-latest) are as follows: Physiology (hunger, thirst, sleep, etc.) Safety/Security/Shelter/Health Social/Love/Friendship Self-esteem/Recognition/Achievement Self actualization/achievement of full potential The basic requirements build upon the first step in the pyramid: physiology.
