Final answer:
Reassuring oneself with positive comments, such as 'Cheer up, Jenna. You know what you're talking about and your topic is really interesting!', in order to reduce fear of speaking to a large audience, is an example of cognitive therapy.
Step-by-step explanation:
The approach of reassuring oneself with positive comments, such as 'Cheer up, Jenna. You know what you're talking about and your topic is really interesting!', in order to reduce fear of speaking to a large audience, is an example of cognitive therapy. Cognitive therapy focuses on changing negative thoughts and beliefs to reduce anxiety and improve psychological well-being.
In this case, Jenna's therapist is helping her challenge her negative thoughts and replace them with positive and reassuring statements. By doing so, Jenna can change her perspective and reduce her fear of speaking to a large audience.
Cognitive therapy is effective for individuals who are open to the power of suggestion and willing to challenge their negative thoughts. It involves identifying and replacing negative thoughts with more realistic and positive ones, leading to a reduction in anxiety and fear.
