Who is credited with developing the concept of the "self-concept"?

The concept of the "self-concept" is primarily attributed to Carl Rogers, who was a prominent figure in humanistic psychology. Rogers believed that the self-concept encompasses an individual's perception and belief about themselves, which significantly influences their behavior and overall psychological health. His theories emphasized the importance of self-acceptance and congruence between the self-concept and actual experiences, asserting that a healthy self-concept can lead to personal growth and fulfillment.

Rogers introduced key ideas such as unconditional positive regard, which highlights the need for acceptance and love from others, and how these factors shape the self-concept. Through his work, he aimed to help individuals understand and develop their true selves, fostering a more authentic and meaningful life experience.

The other figures mentioned, while influential in psychology, did not focus on the self-concept in the same foundational way Rogers did. Sigmund Freud's work revolved around the unconscious mind and psychosexual development, Abraham Maslow is known for his hierarchy of needs and self-actualization, and Erik Erikson explored psychosocial development across the lifespan. Each of these theorists contributed to our understanding of human behavior, but Rogers is the key figure associated with the development of the self-concept.
