- Hormones
- ROLE
- in the womb hormones act upon the brain development and stimulate growth of reproductive organs
- at puberty, a burst of hormonal activity causes the secondary sex organs
- TESTOSTERONE
- predominant in men (women produce 10% of what men do)
- development of male sex organs
- produced at week 8 of gestation
- masculinising the brain, development of specific areas like spatial skills, competition and aggression
- Deady et al research support, found it has an impact on typical male and female behaviours, key role in gender development
- correlational, cause and effect can't be established
- socially sensitive, high levels of masculinity implies men are not natural carers, not only biological facts contribute
- OESTROGEN
- primarily female, small amounts in men
- feminises the brain, promoting neural connections for equal use of both hemispheres
- determines female sexual characteristic and mestruation
- responsible for physical and emotional changes during menstruation e.g PMS
- evidence for it being necessary for female only behaviours from Albrecht and Pepe (1997)
- increasing oestrogen levels in pregnant babboons led to hieghtened cortisol production which assisted in the development of foetuses. Key role in sex behaviours
- uses scientific methods, e.g to measure oestrogen levels and cortisol production. Objective, firm conclusions in dev of sex
- considerable objections to PMS, stereotypes female experience, leads to dismissal of women's emotions
- primarily female, small amounts in men
- OXYTOCIN
- a hormone that acts as a neuro transmitter.
- produced by men and women to control key aspects of the reproductive system
- reduces the stress hormone cortisol
- facilitates bonding
- the 'love' hormone
- released in large amounts during labour, make women fall in love with their babies. Stereotype that men aren't as good caregivers
- the 'love' hormone
- facilitates bonding
- research support, Van Leengoed et al (1987) found a relationship with maternal behaviour
- rat mothers injected with an antagonist of oxytocin to inhibit production showed maternal behaviours later, link to gender dev
- can't extrapolate to humans, we have much more complex neuro anatomy
- criticised on the grounds of animal ethics, operating under the premisies of the hierarchy of intelligence suggests it okay to operate on animals.
- pointless to hurt animals when results cannot be generalised
- criticised on the grounds of animal ethics, operating under the premisies of the hierarchy of intelligence suggests it okay to operate on animals.
