Definition and meaning
Nonverbal communication encompasses all forms of information conveyed without words — including body language, facial expressions, gestures, eye contact, posture, and tone of voice. Research suggests that a significant portion of interpersonal communication is nonverbal. In presentations, nonverbal cues strongly influence how a message is received: open posture conveys confidence, eye contact builds trust, and a steady voice signals authority. Presenters who align their nonverbal signals with their verbal content are generally perceived as more credible and engaging.
