Child Development - Sex & Gender Flashcards
What is the definition of sex?
Sex is a person’s biological status
Whether they are male or female
What is the definition of gender?
Gender is an individual’s learned and cultural status
Whether they are masculine or feminine
What is the Mullerian system?
In the first 6-8 weeks of development, all foetuses have the same undeveloped sex organs
How is sex determined?
Whether someone has XX or XY chromosomes
The presence or absence of the SRY gene determines whether the foetus will develop to be male or female
What is the role of the SRY gene?
It codes for the protein TDF
testis determining factor
What is the role of TDF?
It influences the development of the gonads so they become testes
The testes produce testosterone
What is the role of testosterone?
Testosterone triggers the development of external male organs
What happens in the absence of testosterone?
The Mullerian system develops into female sex organs
What are the 3 stages that lead to the development of gender identity?
- prenatal hormones
- development of male or female genitalia
- parents assign as male or female and raise the child accordingly
How are hormones involved in gender identity?
The same prenatal hormones that affect genitalia and the organisation of the brain are involved in gender identity
How do sex hormones differ in males and females?
The same sex hormones exist in males and females
They differ in quantity and the effects that they have on the body
What are the main sex hormones?
testosterone, oestrogen and oxytocin
What does a biological approach to gender suggest?
There is no difference between sex and gender
Biological sex creates gendered behaviour
What happens during puberty?
Hypothalamus releases a hormone which affects the anterior pituitary gland
This causes gonads to become more active
They control the development of SSCs
What characteristics is testosterone associated with?
Aggressive behaviour, high sex drive and poor language development
How does rearing influence gender identity?
A child develops their own gender identity by being told they are either male or female
