What facial cue is an example of non-verbal communication?

Facial expressions serve as a fundamental aspect of non-verbal communication because they convey emotions, attitudes, and reactions without the use of words. This silent form of expression can communicate a wide range of feelings, such as happiness, sadness, anger, or surprise, often more effectively than verbal communication. For example, a smile can indicate friendliness and approachability, while a frown can signal discontent or confusion.

In contrast, written instructions, imitating someone’s speech, and providing verbal directions all rely on spoken or written words and therefore do not fall under the category of non-verbal communication. Written instructions and verbal directions explicitly present information through language, while imitating someone’s speech focuses on the style of verbal communication rather than the visual or emotional elements conveyed by facial expressions. Thus, the primary significance of facial expressions lies in their ability to express complex human emotions and social cues without the necessity of spoken words.
