Which method involves the use of body movements to communicate?

The method that involves the use of body movements to communicate is gesture. Gestures are specific movements of the hands, arms, or other parts of the body that convey meaning or represent ideas, emotions, or information without the use of spoken or written language. This non-verbal form of communication can enhance understanding and add nuance to verbal conversations, making it a vital aspect of interpersonal communication.

While language encompasses both spoken and written forms of communication, it is not solely dependent on body movements. Sign language also uses gestures to convey meaning, but it represents a structured form of communication used primarily by the deaf and hard-of-hearing community, with its own grammar and syntax. Expression typically refers to facial movements that convey emotions or feelings, rather than the broader category of body movements defined as gestures. Thus, gesture is the most accurate choice to represent body movements used in communication.
