Needs such as food, shelter, sleep, and homeostasis (the body's ability to maintain its natural state)
These are the needs that are critical for survival
If these needs are not satisfied the human body cannot function optimally
Maslow considered physiological needs the most important as all the other needs become secondary until these needs are met
Safety Needs
Expand beyond the physical to include emotional safety, order and predictability, routines, and stability
Love and Belonging Needs
The need to belong and be loved by others becomes important once physical and safety needs are met
Esteem Needs
The need or desire for a stable, firmly based, (usually) high evaluation of themselves, for self-respect, or self-esteem, and for the esteem of others
Self-Actualization
The personal desire to do something substantial that helps us to reach our fullest potential
The specific form this need takes varies greatly from person to person
The five-stage model can be divided into deficiency needs (D-needs) and growth needs (B-needs)
Deficiency needs
Arise due to deprivation and motivate people when they are unmet. The motivation to fulfill such needs will become stronger the longer the duration they are denied.
Growth needs
Do not stem from a lack of something, but rather from a desire to grow as a person. Once these growth needs have been reasonably satisfied, one may be able to reach the highest level called self-actualization.
Additional Needs in Maslow's Hierarchy
Cognitive Needs (knowledge and understanding, curiosity, exploration, need for meaning and predictability)
Aesthetic Needs (appreciation and search for beauty, balance, form, etc.)
Transcendence Needs (motivated by values which transcend beyond the personal self)
