Research has found that women smile more often than do men.  The particular smile that women display is called a non-Duchenne (or false) smile.  However, little is known about whether women are aware of displaying this smile, and if they are, what they believe the function or outcome of non-Duchenne smiling will be.  This summer an undergraduate student and myself will run a lab study to test the following:  1) whether women are aware of their smiling behavior, 2) what the perceived function/outcome of the non-Duchenne smile is, and 3) when and why men in low power positions display this type of smile.
