Which model outlines five levels of needs, from physiological to self-actualization?

The model that outlines five levels of needs, arranged from the most basic physiological needs to the highest level of self-actualization, is indeed the Hierarchy of Needs. Proposed by psychologist Abraham Maslow, this theory suggests that human beings are motivated by a series of hierarchical needs, starting with fundamental requirements like food, water, and shelter, which ensure survival. As individuals fulfill these basic needs, they can then address higher-level needs, such as safety, love and belonging, esteem, and ultimately, self-actualization—the realization of one's potential and personal growth.

This model emphasizes the idea that higher-level needs become prominent only after lower-level needs are satisfied, providing insight into human motivation and behavior. For example, a person struggling to meet their physiological needs is less likely to be concerned with esteem or self-actualization. Understanding this hierarchy helps in various areas, such as psychology, education, and even management, as it speaks to what drives individuals at different stages of their life and development.
