  • Sexual Competition


I am a SeNSS-funded Psychology PhD researcher. I have a great interest in understanding women's sexuality, and in particular in understanding sex differences in arousal. My PhD research focuses on investigating previous (the preparation hypothesis) and novel (empathy and sexual competition) explanations of women's bisexual arousal patterns. I use physiological measures of sexual arousal in my research including plethysmography, and pupil dilation. I am also currently exploring new methods to measure lubrication in women, to assess the validity of the preparation hypothesis.
