Which theory describes human development as a series of needs structured in a pyramid?

Maslow's Hierarchy of Needs is the theory that describes human development as a series of needs structured in a pyramid. This model posits that individuals are motivated by a series of hierarchical needs, starting from basic physiological requirements at the base of the pyramid, such as food, water, and shelter, and moving through layers of safety, love and belonging, esteem, and ultimately reaching self-actualization at the top.

This framework emphasizes that lower-level needs must be met before individuals can focus on higher-level psychological and self-fulfillment needs. By understanding this concept, caregivers and practitioners in juvenile settings can better recognize the importance of addressing fundamental needs before expecting youth to engage in higher-level emotional or social development. This makes Maslow's theory particularly relevant in fields such as education, psychology, and social work.
