When a speaker emphasizes their point visually, which aspect of communication are they utilizing?

The correct choice highlights the significance of non-verbal communication in delivering a message effectively. Non-verbal communication encompasses all forms of conveying information that do not involve spoken or written words. This includes body language, facial expressions, gestures, and visual aids, all of which can significantly enhance a speaker's point.

When a speaker emphasizes a point visually, they may use gestures, maintain eye contact, or incorporate visual aids such as slides or charts. These techniques serve to reinforce the message and make it more engaging for the audience. By tapping into non-verbal cues, the speaker can create a stronger emotional connection and ensure that their main ideas resonate more effectively with their listeners, thereby enhancing comprehension and retention.

Verbal communication focuses solely on the spoken or written word, while interpersonal communication relates more to the interactions between individuals in a conversational context. Written communication, on the other hand, involves written text, which does not play a role in the visual emphasis described.
