Depends on who does the lying. Can you act like you are lying? I mean, true acting. Say you are to play someone who is lying as a character, and the audience has to feel you are lying.

It is possible for someone to act out like that, without them realizing. Others may pick up on whatever it is you do, but may not be sure about what exactly it is.

I would say a person that is lying does look away, blinks, and puts his/her arm behind his/her head. But that's also someone who is very uncomfortable does. Most people would be uncomfortable lying, and act out as uncomfortable.

There is this submissive way of looking away. If a person doesn't give you his/her full attention, then that is not something that is attractive.

You don't have to actually make eye contact to not give off bad vibes by looking away/acting submissive.
