Does eye contact really mean anything?
I personally don't trust anybody that can't look me in the eye when I'm talking to them. Its just a trust test for for other people & it's proven to be about 99% correct.
It COULD. That doesn't mean it DOES.
It depends on how long contact is held.
Yes, usually when a person is lying you can see it in their eyes...
Eye contact means that you are intrigued or listening to the person giving the time to talk or interact with you. It's more of an act of kindness then a priority.
eye contact means more to girls and adults more
Had my first real eye contact at about 12 years old. The other guy was about 15 - my first ever black eye.
