The term "hierarchy of human needs" refers to Maslow's theory that human beings have basic needs that must first be met before they can focus on higher-level needs. However, there are several synonyms for this concept. One of the most common synonyms is "Maslow's hierarchy of needs," which refers specifically to Abraham Maslow's version of the theory. Other synonyms include "needs hierarchy," "human needs pyramid," "hierarchical needs model," and "need hierarchy theory." These terms are often used interchangeably and refer to the same general concept of human needs being arranged in a hierarchical order. Regardless of the terminology used, the importance of understanding and meeting human needs cannot be overstated for fostering healthy individuals and societies.
