Human Needs Theory posits that individuals have fundamental needs that must be met for them to thrive. These needs can be categorized into basic physiological requirements, such as food and shelter, as well as psychological needs like belonging, esteem, and self-actualization. The theory emphasizes that unmet needs can lead to conflict and dissatisfaction. The framework is often associated with the work of Abraham Maslow, who created a hierarchy of needs, illustrating how higher-level needs become important only after lower-level needs are satisfied. Understanding these needs can help in various fields, including psychology, sociology, and conflict resolution.
