Have you ever wondered why you sometimes take an almost immediate liking to a person you have just met? We often get the first impression of a people based on the color of a person’s skin or the manner in which he or she dressed. Meaning is conveyed not only by words or verbal languages but also by nonverbal communication systems, such as body behaviors.
Nonverbal communication is important because we use the actions of others to learn about their affective emotional states .Our emotions are reflected in our posture, face, and eyes—be it fear, joy, anger, or sadness—so we can express them without ever saying a word .For this reason, most of us rely heavily on what we learn through our eyes.
