We looked at evidence using correlations between 2D:4DR (a finger-length ratio related (but only indirectly) to sex-hormone exposure before birth) and gender role / gender identity as identified using questionnaires - this doesn't provide very strong evidence for the importance of hormones in gender development, but does it significantly weaken the biological explanation?
We also very briefly introduced the Bruce / Brenda / David Reimer case (subject of the book-club book). Here is the documentary in case you're not much of a reader:
Here is the presentation from the lesson. Notes for Tuesday next week:
- Outline research support for the role of genes and hormones:
- Animal studies (Young 1966)
- Case studies with abnormal individuals (Money)
- Correlations with normal populations (Troche et al 2007)
- Discuss methodological issues
- Draw an overall conclusion
