Which term refers to using hands to create a visual representation of a word?

The term that refers to using hands to create a visual representation of a word is "illustrators." Illustrators are gestures that accompany speech, enhancing the verbal message through non-verbal means. They help to clarify or emphasize what is being said and can provide additional context or emotional nuance to the verbal communication.

In this scenario, illustrators can be seen when someone uses their hands to depict the shape, size, or movement related to what they are describing — for instance, using hand motions to illustrate the dimensions of an object or the action of throwing a ball. This form of gesture is integral to effective communication as it can aid the listener’s understanding and engagement.

The other choices relate to different concepts in non-verbal communication. Regulators are gestures that control or regulate the flow of conversation, such as nodding to encourage someone to continue speaking. Emblems are specific gestures that have a direct verbal translation, like a thumbs-up meaning "good" or "okay." Paralanguage refers to the vocal elements that accompany speech, such as tone, pitch, and volume, rather than hand gestures. Each of these concepts serves a different role in communication but is not specifically about using hands to visually represent words.
