Does communication through text alone reduce coordination of communication? In traditional forms of communication, head nods, smiles, eye contact, distance, tone of voice, and other nonverbal behavior give speakers and listeners information they can use to regulate, modify, and control exchanges. Electronic communication may be inefficient for resolving such coordination problems as telling another person you already have knowledge of something he or she is explaining (Kraut, Lewis, & Swezey, 1982).
