Nonverbal communication plays an important role in effectively communicating messages. It can provide a crisper communication and show a person's intentions more clearly than verbal communication alone. There are several types of nonverbal communication, including kinesics (body movements and facial expressions), posture, gestures, haptics (touching), and movement/body position. Nonverbal communication serves functions like expressing emotions, attitudes, accompanying speech, self-presentation, and rituals like greetings. Both positive and negative aspects of nonverbal communication need to be considered, as it can help or hinder understanding depending on whether verbal and nonverbal signals are aligned.
