Nonverbal signals primarily convey information about what?

Nonverbal signals play a crucial role in communication, often conveying emotions, attitudes, and reactions that may not be expressed verbally. Option C highlights listener engagement and emotional reactions, which are key aspects of nonverbal communication. These signals can include facial expressions, body language, posture, eye contact, and physical distance. They effectively communicate how interested someone is in the conversation and what emotions they are feeling in response, thus enhancing or contradicting the verbal message being shared.

When considering the other options, the clarity of spoken language relates more to verbal communication and may not necessarily be impacted by nonverbal cues. Personal opinions and beliefs, while they can be reflected in nonverbal behavior, are more subjective and may not be as universally interpretable across different contexts as engagement and emotional responses are. Understanding how well someone grasps a spoken message typically relies on verbal feedback and discussion rather than nonverbal cues. Therefore, focusing on listener engagement and emotional reactions provides a more accurate representation of what nonverbal signals primarily convey.
