The Barrett Adaptation of Maslow's Hierarchy of Needs is a modification of Abraham Maslow's well-known theory of human motivation, which proposes that individuals have five levels of needs that must be met in order to achieve self-actualization. In the Barrett Adaptation, Maslow's five levels are expanded to include two additional levels, for a total of seven. Here are the seven levels, from the most basic to the most advanced: Viability: This level includes basic physiological needs such as food, water, and shelter, which are necessary for survival. Relationships: This level includes the need for social connection and interpersonal relationships, such as friendships, family, and romantic partnerships. Performance: This level includes the need for self-respect and the respect of others, as well as a sense of accomplishment and achievement. Evolution: This level includes the need for personal growth, creativity, and fulfillment of one's potential. Alignment: This level includes the need for a sense of purpose, meaning, and alignment with one's values and beliefs. Collaboration: This level includes the need to contribute to something beyond oneself, such as a community, society, or the world at large. Contribution: This level represents the highest level of human development, in which an individual experiences a sense of oneness with all things and recognizes the interconnectedness of all life. At this level, individuals are focused on making a meaningful and lasting contribution to the world. The Barrett Adaptation of Maslow's Hierarchy of Needs emphasizes the importance of personal growth, creativity, and service to others in achieving self-actualization and spiritual development. It suggests that as individuals progress through the levels of needs, they become more focused on higher-order goals and are better able to contribute to the greater good.
