Final answer:
The question refers to Maslow's hierarchy of needs, which indicates that basic physiological and security needs must be satisfied before higher-level growth like self-actualization can occur. This concept is studied within social studies and psychology.
Step-by-step explanation:
The Epstein Model, commonly referred to as Maslow's hierarchy of needs, is a concept that falls within the realm of social studies and psychology. It posits that certain basic needs must be fulfilled before individuals can focus on higher-level growth and self-actualization. At the base of the pyramid are physiological needs necessary for survival, such as food, water, and shelter. Following these are needs for security and safety, relationships and belonging, esteem, and confidence. The pinnacle of Maslow's pyramid is self-actualization, which represents reaching one's full potential. This model suggests that meeting lower-level needs is a prerequisite for achieving self-actualization. Additionally, as society grows, there is an increased complexity in securing these needs, and the requirement for free energy and matter is vital for the growth, reproduction, and maintenance of living systems.
