Abraham Maslow is well renowned for proposing the Hierarchy of Needs Theory in 1943. This theory is a classical depiction of human motivation. This theory is based on the assumption that there is a hierarchy of five needs within each individual. The urgency of these needs varies. These five needs are as follows-
Physiological needs– These are the basic needs of air, water, food, clothing and shelter. In other words, physiological needs are the needs for basic amenities of life. Safety needs– Safety needs include physical, environmental and emotional safety and protection. For instance- Job security, financial security, protection from animals, family security, health security, etc.
Social needs- Social needs include the need for love, affection, care, belongingness, and friendship. Esteem needs– Esteem needs are of two types: internal esteem needs (self- respect, confidence, competence, achievement and freedom) and external esteem needs (recognition, power, status, attention and admiration). Self-actualization need– This include the urge to become what you are capable of becoming / what you have the potential to become. It includes the need for growth and self-contentment. It also includes desire for gaining more knowledge, social- service, creativity and being aesthetic. The self- actualization needs are never fully satiable. As an individual grows psychologically, opportunities keep cropping up to continue growing.
According to Maslow, individuals are motivated by unsatisfied needs. As each of these needs is significantly satisfied, it drives and forces the next need to emerge. Maslow grouped the five needs into two categories – Higher-order needs and Lower-order needs. The physiological and the safety needs constituted the lower-order needs. These lower-order needs are mainly satisfied externally. The social, esteem, and self-actualization needs constituted the higher-order needs. These higher-order needs are generally satisfied internally, i.e., within an individual.
