Which of the following terms describes the term used when love, hate, or prejudice are employed to encourage an audience response?

The term that best describes the use of love, hate, or prejudice to encourage an audience response is emotional appeal. Emotional appeal refers to persuasive techniques that evoke feelings to sway the audience's attitudes or actions. It involves tapping into the audience's emotions such as compassion, fear, or pride to create a stronger connection with the message being conveyed.

In public speaking, effective speakers often utilize emotional appeal to provoke a desired reaction, whether that is to motivate, inspire, or sometimes even manipulate the audience's feelings regarding a particular topic. Speakers who recognize the power of emotions can enhance their messages substantially, making them not only more impactful but also more memorable.

Other terms in the options, such as egocentrism, regionalism, or evaluative listening, do not specifically focus on the emotional aspect of persuasion in the same way that emotional appeal does. Egocentrism relates to a person's inability to see a situation from another's perspective, regionalism focuses on characteristics of a region or local dialect, and evaluative listening pertains to analyzing and judging the content of a message. None of these directly pertains to the strategic use of emotions in order to elicit a response from the audience. Thus, emotional appeal is the most accurate choice for this question.
