Maslow’s Hierarchy

Home/Maslow’s Hierarchy

Maslow’s hierarchy of needs – also called the hierarchy of needs – is a model of human psychological motivation and needs, as developed by Abraham Maslow. Within this framework, human psychological needs and corresponding motives are divided into primary needs and secondary needs. Primary needs are physiological in nature. They include such things as food, water, shelter and sleep. Secondary needs are internal states like the desire for power, achievement, belonging, opportunities for self-development, input into collective decision making, etc. People’s and societies’ needs can change over time as people move on to new ones that become more intensified and important to them.
