The current state of psychological research in nonverbal communication is briefly summarized and several problems are noted. Reciprocal communication (RC) is suggested, defined, and qualitatively investigated as a way of describing the experience of emotional compatibility in communication, with an emphasis on form, degree, and timing as fundamental aspects of nonverbal communication. Support for three different levels of emotional compatibility (fully, partially, and nonreciprocal) is found. Variation in the interpretation of nonverbal communication when communication is perceived as either intentional or unintentional is noted, and a system of categorizing reciprocal communication is suggested. Further patterns in nonverbal communication are observed, and terminology suggested.
