Final answer:
Body language is a non-verbal form of communication that complements linguistic communication. It includes aspects such as facial expressions, gestures, posture, and movement. Observing body language can provide insights into emotions, meaning, and a person's level of engagement in communication.
Step-by-step explanation:
Body language is a form of non-verbal communication that accompanies linguistic communication. It includes various aspects such as paralanguage (tonal aspects of vocal communication), kinesics (body movements and gestures), posture, facial expressions, and displays of affection.
Body language can help convey additional meaning and emotions in communication, complementing verbal communication. For example, facial expressions and gestures can provide insight into a person's emotional states, while posture and movement can help interpret meaning in public speaking.
Observing body language can also be helpful in understanding a person's response to questions and their level of engagement. Visual cues such as eye contact, fidgeting, and smiling can reveal a person's attitude and level of interest.
