The Effects of Diurnal Variation in Testosterone on Masculinity and Attractiveness Ratings
MetadataShow full item record
Several studies have been conducted examining the effects of various hormones (e.g., estrogen, estradiol, testosterone, among others) on men and women, as it relates to the way in which he or she perceives attractiveness. The present study is an ongoing study, and therefore a projected study. The purpose of this study is to follow up to 2 previous studies examining the effects of diurnal testosterone in women and how that affected facial preferences in men. The current study includes male participants, whereas the previous 2 experiments did not, and it focuses primarily on how diurnal testosterone and its effects on perceived attractiveness vary from the morning to the evening. Based on the previous 2 studies, it was hypothesized that morning participants are more likely to prefer masculine faces and bodies than evening participants, given that testosterone levels are higher in the morning. Because the study is still ongoing, and this is a projected study, an answer to the hypothesis cannot be given, nor can the hypothesis be accepted or refuted. However, because of previous research on the topic, it is likely that the hypothesis will be accepted and the hypothesis for the projected study is that female participants during the morning session will have higher preferences for masculinity that when they are tested in the evening. Similarly, males will have higher preferences for femininity when tested in the morning than when tested in the evening.
