What term refers to non-verbal communication that involves facial movements, gestures, and posture?

The term that refers to non-verbal communication encompassing facial movements, gestures, and posture is body language. Body language is a broad concept that includes various forms of non-verbal cues used to convey messages without spoken words. It encompasses how an individual uses their body to express feelings, reactions, and attitudes, allowing for a rich form of communication that complements verbal messages.

While sign language is a method of communication using visual gestures and signs, it is specifically designed as a complete language system for the deaf and hard of hearing, which is more structured and grammatical. Facial expressions are indeed a component of body language but only focus on the facial movements themselves rather than the full range of non-verbal cues, including posture and gestures. Kinesics, on the other hand, is a term often used to refer to the study of body movements in communication; however, body language is the more widely recognized and applicable term to describe the overall concept of non-verbal communication that involves gestures, facial expressions, and posture.
