From: The effect of smiling on the perceived age of male and female faces across the lifespan
The aging effect of smiling (AES) in different age groups of faces in Experiment 3 (full faces). Participants were middle-aged adults. Note, that as in Experiment 1a, for faces of middle-aged adults, AES was found only for male faces, but not for female faces. No AES was found for faces of old adults. Error bars represent standard errors of the mean.
