Facial cues are non-verbal signals expressed through facial expressions, movements, and features. They play a crucial role in communication, helping convey emotions such as happiness, sadness, anger, or surprise. Understanding these cues can enhance interpersonal interactions and improve emotional intelligence. Common facial cues include raised eyebrows indicating surprise, a frown suggesting discontent, or a smile representing friendliness. These expressions can vary across cultures, but many basic emotions are universally recognized. Recognizing and interpreting facial cues can aid in social situations, making it easier to connect with others and respond appropriately to their feelings.
