Nonverbal Communication Is More Ambiguous
In Chapter 3 "Verbal Communication", we learn that the symbolic and abstract nature of language can lead to misunderstandings, but nonverbal communication is even more ambiguous. As with verbal communication, most of our nonverbal signals can be linked to multiple meanings, but unlike words, many nonverbal signals do not have any one specific meaning. If you’ve ever had someone wink at you and didn’t know why, you’ve probably experienced this uncertainty. Did they wink to express their affection for you, their pleasure with something you just did, or because you share some inside knowledge or joke?
Just as we look at context clues in a sentence or paragraph to derive meaning from a particular word, we can look for context clues in various sources of information like the physical environment, other nonverbal signals, or verbal communication to make sense of a particular nonverbal cue. Unlike verbal communication, however, nonverbal communication doesn’t have explicit rules of grammar that bring structure, order, and agreed-on patterns of usage. Instead, we implicitly learn norms of nonverbal communication, which leads to greater variance. In general, we exhibit more idiosyncrasies in our usage of nonverbal communication than we do with verbal communication, which also increases the ambiguity of nonverbal communication.
