Brief Statement of Original Result Ganel (2015) showed subjects images of faces with smiling expressions and neutral expressions. He found that smiling faces were perceived to be older than neutral faces.

Detailed Description of Method/Results A power analysis based on the effect size of the original experiment (d = 1.812) indicated we would need at least n = 10 subjects to detect an effect of that size with Power (1-β) = .80 and α = .05.

Students from a research methods class at the University of Scranton, who were unfamiliar with the task participated in this study.

A series of sixty faces, half of which were smiling and half with a neutral expression, appeared one at a time on a computer screen. Each face was the head (with hair) and upper torso of a sitting person against a neutral background. There were an equal number of male and female faces presented to each participant. Subjects were given as much time as necessary to estimate the age of each face presented on the screen as accurately as possible. When one age response was entered, the next face appeared. This continued until subjects entered responses for all sixty faces. This study used the same face database as the original study.

A paired samples t-test was used to determine whether smiling faces were rated as older than neutral faces. As seen in the figure, the mean age estimate of the smiling faces was significantly higher than the mean age estimate of the neutral faces, t(15) = 3.06, SE = .52, p = .008 (two-tailed), d = .79.

Any Known Methodological Differences
(between original and present study)?
Four fewer subjects were involved in this study than in the original study. The original study was conducted in a different country (Israel). The phrasing of the task instructions was slightly different, though the overall instructions were the same.
