The current volume, featuring 28 contributions from cutting-edge researchers, emphasizes uses, purposes, origins, and consequences of nonverbal communication in the lives of individuals, dyads, and groups - in other words, the behaviour of human beings. As such, the volume as a whole is not just about communication systems per se nor the impact on humans of the physical environment, whether built or natural. Instead, the volume focuses on humans engaging in nonverbal communication and the communicative and psychological aspects of this behaviour. Nonverbal behaviour is an inclusive category and includes all emitted nonverbal behaviour that may be subject to interpretation by others, whether the behaviour is intentionally produced or not. This panoramic volume, edited by two of the world's leading authorities on nonverbal communication, contains 28 essays presenting the state of the art in the domain of nonverbal behaviour study.
