What does Maslow's Hierarchy of Needs illustrate?

Maslow's Hierarchy of Needs is a psychological theory that organizes human needs into a five-tier model, illustrating how these needs develop from the most basic to more complex levels. At the base of the hierarchy are physiological needs, such as food, water, and shelter, which must be satisfied before individuals can focus on higher-level needs. Once these basic needs are met, individuals seek safety, followed by social needs such as belonging and love. The next level is esteem needs, which include self-esteem and respect from others. At the top of the hierarchy is self-actualization, the realization of an individual's potential, self-fulfillment, and personal growth.

This structured progression emphasizes that individuals must fulfill lower-level needs before they can pursue higher-level aspirations. This theory is significant in understanding human motivation and behavior in various contexts, from personal development to mental health and education.
