Needs Theory is a psychological framework that categorizes human motivations into different levels of needs. Developed by Abraham Maslow, it is often depicted as a pyramid, with basic physiological needs at the bottom, followed by safety, love and belonging, esteem, and self-actualization at the top. According to this theory, individuals must satisfy lower-level needs before they can focus on higher-level ones. The theory suggests that unmet needs can lead to dissatisfaction and hinder personal growth. For example, if someone lacks safety or security, they may struggle to form relationships or pursue self-improvement. Understanding these needs can help in various fields, including psychology, education, and business.
