Which of the following methods of selecting a speech topic involves the process of self-discovery and the consideration of personal interests?

The method that involves self-discovery and consideration of personal interests is monitoring behavior. This process encourages speakers to reflect on their own experiences, preferences, and values, helping them to connect with topics that truly resonate with them. By analyzing their behavior and interests, individuals are more likely to identify subjects they are passionate about, leading to a more engaging and authentic speech.

In contrast, other methods like group brainstorming involve collaboration with others to generate ideas, clustering focuses on visually organizing ideas around a central theme, and surveying entails gathering input from a wider audience about what topics might be interesting. While these methods can be effective for topic selection, they do not emphasize personal reflection in the same way that monitoring behavior does.
