What term describes nonverbal signals expressed through facial expressions and body gestures?

The correct choice captures the essence of how individuals convey messages without spoken words. Body language encompasses a wide range of nonverbal cues, including facial expressions, posture, and gestures, all of which can significantly affect communication and the way messages are interpreted. These cues can convey emotions, attitudes, and reactions, providing additional context to verbal communication.

While nonverbal communication is a broad term that includes all forms of communication without words, including body language, it does not specifically emphasize the gestures and physical signals that body language refers to. Gestural language could imply a more formal system of communicated gestures (like sign language), and signal behavior is not a widely recognized term within communication studies. Thus, "body language" is the most precise term to describe the nonverbal signals expressed specifically through facial expressions and body gestures.
