Biological Approach To Gender Flashcards
Boy/girl
Males - xy
Females -xx
Original system can develop into both male or female
WOLFERIAN
BOY = SRY gene - TDF - Gonads to testes - Testosterone - Penis
MULLERIAN
GIRL = No SRY gene - Gonads to ovaries
Puberty
Hypothalamus releases hormones which affect pituitary gland
Gonads become active
Body develops sexually
Barista boys
Raised as girls until puberty
XY gene mutation = penis didn’t develop durning pregnancy
At puberty they went down the wolferian system
Once boys gender changed straight away
Biology changed so dos gender
David/Brenda
Born male
Accident when circumcised damages penis and rendered it useless = psychologically damaging
Raised as a girl
Never happy - felt she was a boy -peed standing up
Biology took over even through she was raised as a girl
Brain development
Testosterone slows down development of left side of the brain and speeds up the right in males Left = language Right = logic Explains male and female characteristics Men = logical Women = attentive
Geshwind and Galaburda
Male babies had larger right hemisphere than left
Visa versa in females
Driesen and Raz
Corpus Callosum (fibres) connecting sides are bigger in females Superior emotional intelligence
Young
Female monkeys
Injected with testosterone in womb
Tomboyish girls compared to sisters who weren’t injected
Males hormones effected the brain development and lead to male characteristics
Vanderburg
Rats
Peas in a pod
Sisters next to bro were more tomboyish that other sisters
Exposure to male hormone effected development and characteristics
Money and Ehrhart
Human babies
Injected with testosterone to cease bleeding
Resulted in tomboyish girls
Children didn’t have abnormal gender identity
Did demonstrate higher than normal cross gender behaviour
Yalom
Female hormones
Girly boys
Children didn’t have abnormal gender identity
Did demonstrate higher than normal cross gender behaviour
Animal research
Extrapolating data?!
Biological processes are similar
Animals are very diff
Deterministic
If you process a certain gene you will be male or female
Some people do not feel they are their biological sex
Reductionist
Complex psychological system in a simple way - faulty genes
No emotional function taken into account
