Experimental setup and salivary testosterone levels. Participants (N = 243) arrived at the lab at 9:00 a.m., had their hands scanned to take 2D:4D measures, completed an intake survey, and gave a baseline saliva sample (“A”) before application of either T or placebo topical gel. After a 4-h loading period, participants came back to the lab and took part in a battery of behavioral tasks. Three additional saliva samples (“B,” “C,” and “D”) were collected during the experiment, all of which indicated elevated T levels in the treatment group compared to the placebo group. The behavioral tasks reported were the main focus of the study, and took place immediately following the participants’ return the lab in the afternoon (after saliva sample B).
