Your Pupils Dilate When You Lie

By Chad Upton | Editor

This is one of the reasons some poker players wear sunglasses (they also do it so they can stare at their opponents without being noticed).

In fact, the neurotransmitters that mediate pupil dilation are closely associated with arousal in general.

This was proven in a recent study which found that pupil dilation is closely associated with memory and attention functions. In controlled tests, researchers were even able to predict the precise moment when subjects made decisions, based solely on a change in pupil size.

Knowing this, you may want to stick to online poker.
