Maslow's (1943, 1954) hierarchy of needs is a motivational theory in psychology comprising a five tier model of human needs, often depicted as hierarchical levels within a pyramid. Maslow stated that people are motivated to achieve certain needs and that some needs take precedence over others.
When the lowest level need is satisfied the person is motivated to move onto the next level of need until that level is satisfied. This widely recognized theory is called Maslowâs Needs Hierarchy Model. The five âbasicâ needs that complete the hierarchy model are: physiological needs, safety needs, belonging and love needs, ego needs, and self-actualization needs (Appelbaum, p.47). Physiological needs consist of the desire for food, water, air, and shelter.
