Maslow's hierarchy of needs

Maslow's hierarchy of needs is a motivational theory in psychology that argues that while people aim to meet basic needs, they seek to meet successively higher needs in the form of a hierarchy. This theory was published by Abraham Maslow in 1943 and the theory still remains valid today.
Maslow's hierarchy of needs is often represented as a 5 tier pyramid, explaining human needs in the order in which they take precedence.
