Maslow’s hierarchy of needs is a motivational theory in psychology that explains the five levels of human needs, created by Abraham Maslow on how humans are inspired to satisfy needs in a hierarchical order. From the bottom upwards, the five needs are physiological, safety, love and belonging, esteem, and self-actualization. The hierarchy goes from the most basic to the most advanced needs, with the ultimate goal being to reach the highest level. His theory differs from more physiological representations of motivations as it’s seen as not just concerned with tension reduction and survival, but also human growth and development.
