Carl Rogers was a humanist psychologist who believed that for a person to grow, they need an environment with genuineness, acceptance, and empathy. Rogers also believed that people are motivated to reach self-actualization by achieving their goals and desires throughout life. A person's self-concept, or view of themselves, is influenced by childhood experiences and others' evaluations and can impact whether they feel positively or negatively about themselves. Rogers introduced the concept of unconditional positive regard, where one accepts and loves a person for who they are without judgment. He also described characteristics of fully functioning people, including trust, acceptance, and enjoying the present moment.
