Which of the following is an example of nonverbal communication?

Nonverbal communication encompasses all the ways in which individuals convey messages without the use of words. This includes body language, facial expressions, gestures, posture, and even the physical appearance of the speaker. The speaker's dress and posture are significant elements of nonverbal communication, as they can influence the audience's perception of the speaker's credibility, confidence, and professionalism. How a speaker stands or moves can convey openness, confidence, or nervousness, while their attire can signal respect for the audience and the occasion.

Visual aids, while aids to communication, rely on verbal explanation to convey messages and therefore do not fall under nonverbal communication. Pausing for effect can enhance oral delivery but is primarily a verbal technique related to rhythm and pacing rather than a nonverbal cue. Reading from a script involves verbal communication, as it explicitly uses spoken language to convey messages rather than indirect expressions or body language. Thus, the emphasis on the speaker's dress and posture highlights essential aspects of how nonverbal cues function in public speaking.
