Maslow's theory proposes a hierarchy of basic human needs, with physiological needs like food and shelter at the bottom, followed by safety, belongingness, esteem, and self-actualization at the top. The theory suggests that lower level needs must be satisfied before higher level needs can be addressed. For learning to occur, basic needs like food, water, shelter and safety must first be met. Once these needs are addressed, people can focus on belonging, esteem, and ultimately self-actualization and personal growth.
