Step-by-step explanation:
Abraham Maslow is most well-known for proposing his Hierarchy of Needs, which is a theory in psychology that prioritizes human needs into different levels. The basic needs for survival, such as food, water, and shelter, must be met before an individual can focus on higher-level needs like social needs and self-actualization. This theory falls under the broader category of humanistic psychology, which emphasizes the positive aspects of human nature and potential for growth.The different levels of Maslow's hierarchy motivate behavior as individuals strive to meet these needs, starting from the most basic physiological needs up to the need for self-actualization. Maslow's work was significant in the shift towards a humanistic approach in psychology, and his concept of the Hierarchy of Needs remains one of the most recognizable psychological theories.
