Behavioral cues are observable actions or signals that indicate a person's feelings, intentions, or reactions. These cues can include body language, facial expressions, tone of voice, and gestures. For example, crossed arms may suggest defensiveness, while a smile can indicate happiness or friendliness. Understanding these cues can help in interpreting social interactions. In various contexts, such as psychology or communication, recognizing behavioral cues is essential for effective interaction. They can provide insights into how someone is feeling or what they might be thinking, allowing for better responses and connections in both personal and professional relationships.
