Understand That Nonverbal Communication Is Multichannel

Be aware of the multichannel nature of nonverbal communication. We rarely send a nonverbal message in isolation. For example, a posture may be combined with a touch or eye behavior to create what is called a nonverbal cluster. Allan Pease and Barbara Pease, The Definitive Book of Body Language (New York, NY: Bantam, 2004), 21. Nonverbal congruence refers to consistency among different nonverbal expressions within a cluster. Congruent nonverbal communication is more credible and effective than ambiguous or conflicting nonverbal cues. Even though you may intend for your nonverbal messages to be congruent, they could still be decoded in a way that doesn’t match up with your intent, especially since nonverbal expressions vary in terms of their degree of conscious encoding. In this sense, the multichannel nature of nonverbal communication creates the potential of both increased credibility and increased ambiguity.

When we become more aware of the messages we are sending, we can monitor for nonverbal signals that are incongruent with other messages or may be perceived as such. If a student is talking to his professor about his performance in the class and concerns about his grade, the professor may lean forward and nod, encoding a combination of a body orientation and a head movement that conveys attention. If the professor, however, regularly breaks off eye contact and looks anxiously at her office door, then she is sending a message that could be perceived as disinterest, which is incongruent with the overall message of care and concern she probably wants to encode. Increasing our awareness of the multiple channels through which we send nonverbal cues can help us make our signals more congruent in the moment.
