Despite what it may be politically correct to believe, when we
meet people for the first time we quickly make judgements
about their friendliness, dominance and potential as a sexual
partner - and their eyes are not the first place we look.
Most researchers now agree that words are used primarily
for conveying information, while body language is used for
negotiating interpersonal attitudes and in some cases is used
as a substitute for verbal messages. For example, a woman can
give a man a 'look to kill' and will convey a very clear message
to him without opening her mouth.
