Though many studies have been conducted on gender differences in olfactory perception, the findings of these studies have been open to question. Females have typically been shown to have a higher sense of olfactory acuity than males, but some critics instead point to the fact that changes in hormonal levels may lead to females being more sensitive to odors, while others believe that males and females are attracted to different smells. In this experiment, besides having participants identify odors, they will be quantifying the intensity of the odors, along with each odour's favorability.
