Abstract

This longitudinal study tracked smiling behaviors in the yearbook photographs of 112 boys and girls between Grades 1, 9, and 12. Results indicated that, while non-significant in 1st grade, gender differences peaked in 9th grade. Unlike past research, both genders shifted smiling rate across this developmental period.
