Twenty female undergraduates (i.e., same gender as the main study participants) aged 18–21
(M = 20.05, SD = 0.95) viewed a PowerPoint presentation of 30 female photos taken from the
18–25 year old category of the photo rating website hotornot.com (for similar method see
[8,15]). All photos were of women judged to be of university age, and were a mix of full-body
and head-only shots to reflect variation in Facebook profile pictures. Photos were rated on a
scale ranging from 1 (very unattractive) to 10 (very attractive).
