Nonverbal behavior refers to the ways in which people communicate without using words. This includes facial expressions, body language, gestures, posture, and eye contact. These nonverbal cues can convey emotions, attitudes, and intentions, often providing more context than spoken language alone. Understanding nonverbal behavior is essential in various fields, such as psychology, communication studies, and sociology. It plays a crucial role in interpersonal interactions, helping individuals interpret social signals and respond appropriately. Misinterpretations of nonverbal cues can lead to misunderstandings in communication.
