Carl Rogers was an influential American psychologist known for developing the humanistic approach to psychology. He believed that every person has the potential for personal growth and self-actualization. His ideas emphasized the importance of a supportive environment, where individuals feel accepted and understood. This approach laid the groundwork for modern therapy practices, focusing on the therapeutic relationship between the client and the therapist. Rogers introduced concepts like unconditional positive regard, which means accepting and valuing a person without judgment. His work has had a lasting impact on fields such as counseling, education, and conflict resolution, promoting empathy and understanding in human interactions.
