What is the role of nonverbal signals in a conversation?

Nonverbal signals play a significant role in enhancing communication by complementing spoken words and conveying emotions that words alone might not fully express. These signals include facial expressions, gestures, posture, eye contact, and tonal variations, all of which can reinforce what is being said or convey additional layers of meaning. For instance, a smile can convey warmth and friendliness, while crossed arms might indicate defensiveness or resistance, even if the person is speaking positively. This interplay between verbal and nonverbal communication enriches interactions, helping to create a more nuanced understanding and establishing rapport between the communicators.

In contrast, nonverbal signals do not serve to distract from the conversation or to entirely replace verbal communication. While they can summarize certain aspects through body language, they are not meant to encapsulate the main points discussed in the same way that verbal summaries would. Therefore, their primary function is to enhance and clarify the communication process, supporting the spoken message rather than overshadowing or substituting it.
