Nonverbal communication is an important and little-understood aspect of human communication. This book deals primarily with two aspects of nonverbal communication: paralanguage and kinesics. "Paralanguage" includes vocalizations such as hissing, shushing, and whistling, as well as speech modifications such as quality of voice (sepulchral, whiny, giggly) or hesitations and speed in talking. The term "kinesics" refers to all body movements. Following an introduction to the field of nonverbal communication, the book provides discussions of the following topics: a model for describing nonverbal behavior in communication; paralanguage; kinesics; sensory communication; the function of silence; the effects upon nonverbal communication of the contexts in which the communication occurs; ways in which individuals' patterns of nonverbal behavior are affected by such factors as their age, geographical location, historical era, and culture; sign language and other language substitutes; and methodology for research in nonverbal communication. The book includes a 60-page bibliography of related publications. (GW)
