Final answer:
Person-Centered Therapy, developed by Carl Rogers, is the correct answer as it stresses the importance of expressing emotions and sharing personal concerns through an environment of genuineness, empathy, and unconditional positive regard.
Step-by-step explanation:
The therapy that emphasizes the expression of emotions and vulnerability in sharing personal concerns is known as Person-Centered Therapy. This approach was developed by Carl Rogers who believed that genuineness, empathy, and unconditional positive regard are crucial in helping clients address their problems.
Unlike psychodynamic therapy which often delves into the unconscious aspects of the client's mind, person-centered therapy focuses on the individual's self-perceived thoughts and feelings. Rogers emphasized that the therapeutic environment should be one that offers unconditional positive regard,
where the client feels fully accepted by the therapist, as well as an empathetic understanding of the client's internal state, and a genuine and authentic presence from the therapist.
