Detailed Description of Method/Results Eleven students from the University of Scranton participated within this study. All subjects were 18 or older.

The independent variable was whether the person in a photo was smiling or had a neutral expression. Each participant was told to estimate the age of individuals in the photos. The photos were blurred through the Gaussian Noise Filter (GNF) with a standard deviation of 20 pixels which maintained spatial low frequency of the image. Stimuli were presented on a Dell computer and a standard QWERTY keyboard was used to register responses.The task included 60 blurred faces, with 30 male faces (15 smiling, 15 neutral) and 30 female faces (15 smiling, 15 neutral).

Participants were tested individually in a session that lasted approximately 20 minutes. Upon arrival, each subject was given a consent form that disclosed all of the pertinent information regarding the study. Participants were told that they would see a series of 60 blurred faces. Participants were shown either a neutral expression photo or a smiling expression photo on each trial. The photos were presented in a randomized order between both facial expressions. Participants were instructed to estimate the age of the individual in the photo by typing on the keyboard. After participants completed the task they informed the researcher and were thanked for their participation.

A paired samples t-test was used to compare the average age estimates between the smiling and neutral faces. The difference in estimated ages between smiling faces (M = 26.40, SD = 3.57) and neutral faces (M = 28.07, SD = 4.35) was statistically significant, t (10) = -2.94, SE = 0.57, p = 0.015, d = 0.88 (power = 0.75). This demonstrates that there was a failure to replicate Ganel (2015) results because neutral faces were perceived to be older than smiling faces, with a mean difference of M = -1.67 [95%CI: -2.94, -0.40].

(between original and present study)?
A different photo database was used, however, all else was the same.
