Overview
body language
Quick Reference
The movement and gestures of the body that communicate to another person non-verbally. There are two aspects of body language; voluntary and involuntary. Voluntary body language comprises movements, gestures, and poses that a person makes with full or partial intention (for example smiling or hand movements). Involuntary body language often takes the form of a facial expression. This suggests that one is engaged with the emotions of the person one is communicating with (for example raising the eyebrow often means one is skeptical or surprised). Body language is very important for marketers to study and understand, particularly those engaged in customer research and interviewing.
