The past three decades have seen tremendous advancement in our knowl­ edge of nonverbal communication. However, much of this work has focused on the structure of nonverbal communication, or on the nonverbal communication process. By comparison, there has been relatively little attention given to skill in nonverbal communication. The concept of nonverbal communication skill focuses on peoples’ abilities to communicate through nonverbal channels. As such, it is an “individual differences” approach to studying nonverbal communication.
