Generally a large part of the message in human communication is
being transmitted nonverbally, through those non-verbal forms. Most of
the described components are culturally and situationally dependent and
therefore not easy to interpret - with the exception of facial
expressions - see
FACS
(Facial Action Coding System) and the
Six Basic
Emotions. Using non-verbal communication sometimes we replace and
sometimes we support or emphasize our verbal communication. It is a
human nature that by nonverbal communication we express emotions. During
normal communication, where the emphasis is on communicating facts or
logical information is a nonverbal communication around 30% while when
we expressing emotional content it can be up to 90% of the message.
