Editing Gender identity (section)

===1950s and 1960s===
During the 1950s and '60s, psychologists began studying gender development in young children, partially in an effort to understand the origins of [[homosexuality]] (which was viewed as a [[mental disorder]] at the time). In 1958, the Gender Identity Research Project was established at the [[UCLA Medical Center]] for the study of [[intersex]] and transsexual individuals. Psychoanalyst [[Robert Stoller]] generalized many of the findings of the project in his book ''Sex and Gender: On the Development of Masculinity and Femininity'' (1968). He is also credited with introducing the term ''gender identity'' to the International Psychoanalytic Congress in [[Stockholm, Sweden]], in 1963.<ref>{{cite book | last1 = Parker | first1 = Richard Guy | last2 = Aggleton | first2 = Peter | title = Culture, Society and Sexuality: A Reader | publisher = [[Psychology Press]] | url = https://books.google.com/books?id=MlZbFt6421gC&pg=PA80 | page = 80 | date = 1999 | isbn = 9781857288117 | access-date = 18 December 2023 | archive-date = 22 February 2024 | archive-url = https://web.archive.org/web/20240222035325/https://books.google.com/books?id=MlZbFt6421gC&pg=PA80#v=onepage&q&f=false | url-status = live }}</ref> Behavioral psychologist [[John Money]] was also instrumental in the development of early theories of gender identity. His work at Johns Hopkins University's [[History of transgender care at Johns Hopkins Hospital|Gender Identity Clinic]] (established in 1965) popularized an [[interactionist]] theory of gender identity, suggesting that, up to a certain age, gender identity is relatively fluid and subject to constant negotiation. His book ''Man and Woman, Boy and Girl'' (1972) became widely used as a [[college textbook]], although many of Money's ideas have since been challenged.<ref>{{cite book| vauthors = Haraway D |title=Simians, Cyborgs, and Women: The Reinvention of Nature |publisher=[[Free Association Books]]|year=1991|isbn=978-0-415-90386-8|location=London|page=133|author-link=Donna Haraway}}</ref><ref>{{cite book | vauthors = Karkazis K | title = [[Fixing Sex|Fixing Sex: Intersex, Medical Authority, and Lived Experience]] | publisher = Duke University Press | date = November 2008 | isbn = 978-0-8223-4318-9 }}</ref>
