This study specifically explored the perceived importance of the following nonverbal factors in the negotiation process: proxemics (location and negotiation site), physical arrangement (seating and furniture arrangement), and kinesics (eye contact, facial expressions and gestures). The participants are professional business negotiators of different nationalities. The findings show that the negotiators' perception about the three factors and their roles in negotiation are consistent with the nonverbal communication literature.
