Final answer:
When counselors accept and value clients without reservation, they demonstrate unconditional positive regard.
Step-by-step explanation:
When counselors accept and value clients without reservation, they demonstrate unconditional positive regard. This concept was emphasized by Carl Rogers, an American psychologist who believed in the potential for good in all people. Unconditional positive regard refers to the therapist accepting the client for who they are, no matter what they might say. It is one of the three features Rogers believed a therapist needed to display to maximize the effectiveness of client-centered therapy, along with genuineness and empathy.
