Doesn’t excessive eye blinking generally indicate a person is lying when questioned by interrogators?
Not sure IRL, but here is a movie quote from "The Negotiator", by character Danny Roman (Samuel L. Jackson):
"A quick lesson in lying. See, this is what us real cops do: We study liars. Example: If I ask you a question about something visual, like your favorite color, your eyes go up and to the left. Neurophysiology tells us your eyes go in that direction, because you're accessing the visual cortex. So you're telling the truth. If your eyes go up and right, you're accessing the brain's creative centers and we know you're full of sh*t. "
Haha, yes I believe it does. Last semester I took a communications class, and my professor who was a strong Libertarian (rare on a college campus) told us in most cases that if someone blinks out of control they are lieing. He told us if we want an example of that just to watch any Nancy Pelosi interview. I laughed out loud, most of my classmates however didn’t think it was funny, and some didn’t know who Nancy Pelosi was.
