To determine if solitary men’s room BO smelled different to the fresh new BO of hitched guys, heterosexual women members rated men’s BO on the five services (elizabeth.g., sexiness, liking). According to earlier look indicating men testosterone levels was indeed certainly (but not rather) associated with healthier smell BO reviews (Rantala ainsi que al., 2006) and single men provides higher levels of testosterone (elizabeth.grams., Unit and you may Dabbs, 1993), i hypothesized one solitary men’s room BO carry out smelling more powerful than that out of married men’s room.

We made no an excellent priori predictions about differences between single and you will married men’s face elegance feedback. Fundamentally, to ensure the capability to examine the brand new BO and you may deal with reviews from solitary and married dudes, people rated new stimulus out of three single and you may about three partnered unknown dudes.
