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 significantly enhances speaker credibility. Eye contact is a nonverbal communication cue that fosters a sense of connection between the speaker and the audience. It signals confidence and engages listeners, making them more likely to trust the speaker.

Establishing eye contact can also create a perception of authenticity and sincerity, contributing to how credible the audience perceives the speaker to be. When a speaker looks directly at the audience, it can further demonstrate that the speaker is knowledgeable and invested in the topic, which reinforces their authority.

While other aspects such as active listening, message clarity, and audience feedback can be influenced by various factors, the direct correlation between eye contact and speaker credibility stands out prominently. Eye contact enhances the listener's comfort and perception of the speaker, thus increasing overall credibility.
