Gender Flashcards
Sex
MALE/FEMALE
- Biological status of male or female that’s determined by chromosomes, hormones and differences in anatomy
Gender
Psychosocial status (roles, attitudes, behaviours) that we associate with being male or female.
- Heavily influenced by social norms and cultural expectations
Transgender
Individual identifies a s agender that doesn’t align with their chromosonal sex
Sex Role Stereotypes
A belief about what is considered typical behaviour, attitudes and characteristics for a male or female
Male Sex Role Stereotypes
- “Breadwinner”
- Leadership
- Independant
- Assertive
Female Sex Role Stereotypes
- Domestic
- Caring
- Gentle
- Sensitive
Androgyny
High level of both masculine and feminine traits/characteristics in the same individual
BSRI’s four categories of gender (1977)
- Masculine (high masc & low fem scores)
- Feminine (high fem & low masc scores)
- Androgyny (high masc & fem scores)
- Undifferentiated (low masc fem scores)
Role of Chromosomes in Males
Y chromosome carries a ‘Sex Determining Region Y’ (SRY), that causes the testes to develop in an XY embryo & produces androgens by week 8 of development.
- these androgens cause the embryo to become a male, without them the embryo would develop into a female.
Role of Chromosomes in Females
There isn’t a ‘sex-determining region’ as they do not have the Y chromosome. The ovaries are developed and start producing oestrogens (such as progesterone),
- with the female hormones causing the embryo to become a female.
David Reimer
- After a botched circumcision, Bruce Reimer was left without a penis, leaving his parents to look to Money’s theory of gender neutrality for help.
- Bruce was raised in a stereotypically feminine way, taking on the name Brenda, wearing girl’s clothes and played with girl’s toys like dolls.
- This experience was psychologically damaging to her, suffering from many emotional problems and, upon finding out about the situation, they went back to living as a male.
Testosterone
A steroid that is involved in the development of male secondary sexual characteristics, though it is also seen in females but at 10% the amount in comparison.
Levels of Testosterone during Development
- At week 8 of pregnancy, the testes have developed and begin producing testosterone, with XY foetuses having much higher levels of testosterone than XX foetuses.
- Between 24 weeks of pregnancy and birth, the testosterone levels have decreased and are low across both sexes.
- For about the first 6 months, there’s a rush of testosterone with higher levels in males, compared to females.
Effects of testosterone
- Development of male sex organs & physical characteristics
- Masculinisation of the brain (development of brain areas linked to spatial skills)
- Association with masculine behaviours (e.g. competitiveness & aggression)
Money & Ehrhardt (1972)
- Studied a sample of girls whose mothers unintentionally took drugs containing testosterone while pregnant.
- Finding that the girls displayed masculine behaviours, like playing energetic sports, and a lack of feminine behaviours, suggesting testosterone plays a very early role in development as this began in utero and therefore supporting a positive correlation between testosterone & masculine behaviours.
Oestrogen
A group of steroid hormones that aid the development of female characteristics and regulate menstruation.
- Can sometimes be seen in males, but they do not produce it biologically and instead gain it from environmental factors.
Effects of oestrogen
- Development of female sex organs & physical characteristics
- Feminising the brain (promoting neural connections for more ‘distributed’ female brain)
- Physical & behavioural effects (premenstrual tension/PMT & premenstrual syndrome/PMS)
- Association with feminine behaviours (e.g. sensitivity & cooperation)
Fitch & Denenberg (1998)
- Studied how the suppressed production of oestrogen by removing the ovaries from female rats 16 days after birth.
- Findingthat this led to an increased corpus callosum in the adults, and treating the rats with oestrogen resulted in a decreased corpus callosum, supporting the idea that oestrogen is associated with a female-like brain.
Oxytocin
A hormone which is also a neurotransmitter produced by both males & females (though females often produce larger amounts), controlling key aspects of the reproductive system).
Effects of oxytocin
- Helps facilitate childbirth through helping stimulating contractions & breastfeeding
- Affects female social behaviour ( such as: mate selection, monogamy, pair bonding)
- Nurturing, acceptance, protection of offspring
Van Leengoed et al. (1987)
- Injected rats with an antagonist of oxytocin to inhibit its production after giving birth.
- This found that the mothers showed a delay in maternal behaviours (e.g. grooming their offspring) & when this wore off, normal maternal behaviour was seen.
- This supports the link between oxytocin & feminine/maternal behaviours.
Kleinfelter’s Syndrome
The presence of an extra X chromosome (so XXY), and occurs due to an error in meiosis.
- These individuals are biologically male (due to having a Y chromosome) with the physical appearance of a male
- affects between 1 in 500 to 1 in 1000.
Psychological effects of Kleinfelter’s Syndrome
- Poor language skills & reading ability (will struggle with education)
- Passive & shy temperament
- Lacking ambition
- Do not respond well to stress
- Problems with memory & problem solving
Physical effects of Kleinfelter’s Syndrome
Reduced body hair
- Possible breast development
- Long “gangly” limbs
- Underdeveloped genitalia & infertility
- Susceptible to health problems that are associated with females (e.g. Breast Cancer)
Turner’s Syndrome
- The lack of an X chromosome (X0), occurring at conception.
- These individuals are biologically female (due to a lack of Y chromosome) with a female physical appearance
- affects 1 in 5000 females.
Psychological Effects of Turner’s Syndrome
- Higher than average reading ability than other girls their age
- Lower than average spatial ability, visual memory, and mathematical skill
- Socially immune (difficulty in social adjustment & relating to peers)
