Different Smiles Can Elicit Distinct Bodily Reactions
By Janice Wood
Smiles are not created equally. Some are expressions of warmth and joy, while others can be mean and domineering.
A new study shows that our bodies react differently depending on the message a smile is meant to send.
Research led by Jared Martin, a psychology graduate student at the University of Wisconsin-Madison, shows that smiles meant to convey dominance are associated with a physical reaction — a spike in stress hormones — in their targets. On the other hand, smiles intended as a reward or to reinforce behavior appear to physically buffer recipients against stress.
