Nonverbal signals are forms of communication that do not involve words. They include body language, facial expressions, gestures, posture, and eye contact. These signals can convey emotions and intentions, often providing more context than spoken language. For example, a smile can indicate friendliness, while crossed arms may suggest defensiveness. Understanding nonverbal signals is essential in various settings, such as interpersonal communication, business meetings, and public speaking. They can enhance or contradict verbal messages, making it important to be aware of both. Effective use of nonverbal communication can improve relationships and facilitate better understanding among individuals.
