Maslow's hierarchy of needs
However, this is not always the case. It is possible for people who suffer from poverty and hunger to still feel love and belonging. Therefore, higher level needs can be met in some cases even if lower levels needs are neglected. Some theorists argue that the levels of the hierarchy are out of order in terms of necessity. Some needs that are higher in the hierarchy may actually appear and become important early in an infant or child’s life. Maslow’s hierarchy is hard to prove scientifically. It cannot be proved false easily. There may not be enough hard, scientific evidence to fully support Maslow’s hierarchy.
