Nonverbal communication conveys information through multiple channels, including auditory, visual, and tactile. Consider what happens when a classmate presents an idea during a discussion. As she speaks, you listen to and interpret the meaning of her words (verbal communication). But at the same time, you’re noticing various nonverbal channels—her vocal pitches and tones (auditory); her facial expressions, gestures, postures, and appearance (visual); and possibly physical contact (tactile), if she’s sitting next to you and happens to touch you. You receive all of this information simultaneously and use it to interpret her meaning: Is she excited about her idea? Unsure? Tired? Her nonverbal communication helps you make sense of the words she says and the meaning she intends.
