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