Communication involves three elements: sender, receiver, and message. In nonverbal communication, the message does not involve words, but rather employs body language. There are three major sorts of nonverbal communication. Symbolic nonverbal communication is the intentional encoding of a message that is decoded by the receiver, the grammar and vocabulary of which must be learned by both sender and receiver. It is propositional in that it is capable of logical analysis (e.g., it can be false). Symbolic nonverbal communication includes sign language, finger spelling, and pantomime, as well as facial expressions and gestures associated with language. In Ekman and Friesen’s (1969) analysis, the latter include emblems with specific “dictionary” definitions, illustrators of what is said, and regulators of interaction flow. Left hemisphere damage produces deficits in both linguistic and symbolic-nonverbal communication.
