Current research

My student Tuesday Watts and I are in the midst of an exciting study on the development of sexual orientation. We are recruiting identical twins with discordant sexual orientations; that is, heterosexual twins with homosexual co-twins. Since these twin pairs are virtually genetically identical, any differences must be due to the environment – so, is it all due to their upbringing after all?

My student Jamie Raines and I are examining to what degree female-to-male transsexuals and male-to-female transsexuals are similar to, or different from, heterosexual and homosexual men and women. This work includes the very first study that will assess the genital arousal patterns of female-to-male transsexuals. We are currently investigating the right tools to do this. Stay tuned!

My student Luke Holmes and I are studying why the large majority of heterosexual women show bisexual genital arousal patterns, whereas lesbians show, on average, stronger genital responses to their preferred sex (women). Why are their arousal patterns so different, and not necessarily in line with their sexual orientations? We examine how both personality and prenatal hormonal influences contribute to theses patterns.

Research interests

My work focuses on sexual orientation: how it is organized, how it develops, and how it affects a person’s life. I use a diversity of methodologies, including self-report, behavioural observations, physiological activity and neurological correlates, and employ an array of quantitative skills in order to pursue my research. I use videos and photos from childhood to examine whether masculine and feminine behaviours during early development predict adult sexual orientation. I also investigate the social impact of these signals. I have used large data sets of family members to investigate potential evolutionary reasons for sexual orientation. In another line of research, I study the association of sexual orientation with physiological sexual arousal in order to illuminate sex differences in sexual response. With a different methodology, pupil dilation, I am currently conducting research that will aid in explaining how early sex and sexual orientation differences in sexual attraction emerge. These studies have broad relevance for understanding how people perceive themselves and others, for the consequences of these perceptions, and for the development of differences between and within the sexes.
