Final answer:
Carl Rogers emphasized unconditional positive regard, genuineness, and empathy as foundational to the healing process in client-centered therapy.
Step-by-step explanation:
Carl Rogers emphasized three features as foundational to the healing process in client-centered therapy: unconditional positive regard, genuineness, and empathy. Unconditional positive regard refers to the therapist accepting the client for who they are, regardless of what they say. Genuineness means the therapist is sincere, authentic, and transparent. Empathy involves the therapist understanding and sharing the client's feelings and experiences. Rogers believed that by providing these three features, individuals were capable of dealing with and working through their own issues.
