Which of the following increases when a speaker makes frequent eye contact with an audience?

When a speaker makes frequent eye contact with an audience, it plays a crucial role in enhancing speaker credibility. Eye contact helps to establish a connection between the speaker and the audience, fostering trust and engagement. When an audience feels recognized and acknowledged through direct eye contact, they are more likely to perceive the speaker as confident and knowledgeable. This perception can significantly boost the audience's overall impression of the speaker's authority on the subject matter.

Additionally, eye contact can signal sincerity and openness, which are key components of credibility. A speaker who shifts their gaze frequently may come across as less trustworthy or as if they are hiding something. Therefore, maintaining eye contact suggests that the speaker is engaged and genuinely interested in communicating effectively with their audience, further solidifying their credibility.
