This document summarizes Abraham Maslow's hierarchy of needs and Carl Rogers' person-centered theory. Maslow proposed that people are motivated to fulfill basic needs like physiological and safety needs before seeking higher-level growth needs such as self-actualization. The Personal Orientation Inventory and other measures were developed to assess self-actualization. Rogers described the actualization tendency in people and the therapeutic conditions of empathy, genuineness, and unconditional positive regard that facilitate personal growth.
