How does facial expression relate to nonverbal communication?

Facial expressions play a crucial role in nonverbal communication because they can convey a wide array of emotions, such as happiness, sadness, anger, surprise, and fear. This ability to express emotions visually helps individuals understand each other's feelings and intents without the need for words. For example, a smiling face can indicate friendliness or approval, while a frown may show disapproval or concern. This nonverbal cue can enhance or complement verbal communication, allowing for a richer interaction.

In contrast, the other options present limitations or inaccuracies regarding the significance of facial expressions. They do not consistently synchronize with verbal communication, as individuals may express emotions that contradict their spoken words. Additionally, while gestures are important, they do not outshine the fundamental role of facial expressions, which often dominate emotional expression in communication. Lastly, facial expressions are not irrelevant; in fact, they are pivotal in human interactions.
