Maslow’s Hierarchy of Needs

Abraham H. Maslow felt as though conditioning theories did not adequately acapture the complexity of human behavior. In a 1943 paper called A Theory of Human Motivation, Maslow presented the idea that human actions are directed toward goal attainment. Any given behavior could satisfy several functions at the same time; for instance, going to a bar could satisfy one’s needs for self-esteem and for social interaction.

Maslow’s Hierarchy of Needs has often been represented in a hierarchial pyramid with five levels. The four levels (lower-order needs) are considered physiological needs, while the top level of the pyramid is considered growth needs. The lower level needs must be satisfied before higher-order needs can influence behavior. The levels are as follows (see pyramid in Figure 1 below).
