Final answer:
Public speakers informed about the illusion-of-transparency phenomenon felt better about their speech and appearance, as they understood that their nervousness was not as visible to the audience as they initially believed.
Step-by-step explanation:
In the study conducted by Savitsky and Gilovich (2003), public speakers who were informed about the illusion-of-transparency phenomenon felt better about their speech and appearance. This psychological phenomenon refers to the tendency for individuals to overestimate the extent to which their inner thoughts, feelings, and physiological states are apparent to others. By understanding that their audience is not as aware of their nervousness as they are, speakers tend to feel less anxious and more confident about their performance.Considering the fear of public speaking, also known as glossophobia, is a common concern, understanding the illusion of transparency can significantly improve one's perception of their public speaking abilities. Toastmasters International and studies on communication skills emphasize the importance of confidence and the misinterpretation of one's own anxiety levels by the audience, which directly relates to the outcomes of the Savitsky and Gilovich study.
