How does nonverbal communication affect the negotiation process?

What will be an ideal response?

The most subtle behaviors in the negotiation process, and often the most difficult to deal with, are usually the nonverbal messages—the use of voice intonation, facial and body expressions, eye contact, dress, and the timing of the discussion. Nonverbal behaviors are ingrained aspects of culture used by people in their daily lives; they are not specifically changed for the purposes of negotiation.
