The author characterizes in brief the nonverbal communication; she analyses the approach to the study of nonverbal communication and introduces different kinds of nonverbal manifestations. Further on, she is concerned with the problem of nonverbal keys, characterized as ''building stones'' of the nonverbal communication that provide information about both emotions and interpersonal relations. She introduces three levels of nonverbal keys that can be interpreted as ambiguous, unambiguously correct, and ambiguously incorrect. At the same time, the author classifies the nonverbal keys according to Krivohlavy. Special attention is paid to the posturology: its definition, as well as the methods of its work (drawbacks included) are presented.
