Consumer motivation is associated with Maslow’s Hierarchy of Needs Theory. According to his theory, motivational forces have different levels of importance. The most common needs are physiological needs (including food and shelter) and safety needs, both of which are tightly connected to basic survival. Higher-level needs include social needs (including relationships and love), esteem needs (including recognition and status) and self-actualization needs (also known as the needs to fulfill oneself). In Maslow’s view, individuals must meet their lower-level needs before being motivated to fulfill their higher-level needs.
