gender Flashcards
define sex
the biological differences between male and females including chromosomes, hormones and anatomy
define gender
the psychological and cultural differences between male and females including attitudes, behaviours and social roles
define sex role stereotypes
type of qualities and characteristics seen as appropriate for each sex
define androgeny
co existence of male and female characteristics within the same individual
what research can be used for sex role stereotypes
seavey et al (1975)
describe seavy et al research
3 month old baby dressed in yellow. then said to one adult it was a boy , to another he said it was a girl and to the other the gender wasn’t revealed. they were left with three toys to play with the baby, a doll, a ball, a plastic ring
- given the doll to play with if they thought it was a girl
- but were more likely to give it the non stereotypical toy ( ring ) if they didn’t know or if they thought it was a boy
- results show that males and females react to babies differently according yo what gender they believe them to be
- certain toys seen appropriate for certain genders
describe the androgeny bem research
respondents required to rate themselves on a seven point rating scale for each item. the scores are classified on the basis if two dimensions eg masculine and feminine
- 20 female traits
- 20 male traits
- 20 neutral traits
- most females scored as feminine and most males scored as masculine
- more people were more androgynous than the extremes , these are more psychologically health as can deal with a range of situations
strengths
- appears to be valid and reliable
- high test retest reliability
weaknesses
- over simplifies a complex concept
- cultural and historic biased
- lacks temporal validity
- understanding of personality
what does the biological explanation include
hormones and chromosomes
what are the main hormones in gender
testosterone
oestrogen
oxytocin
describe testosterone
a hormone that is produced mainly in the males testes and in small amounts in the ovaries
- adds masculinity
- associated with male type behaviours eg aggression, competitiveness and higher sex drive
research for testosterone
nanne van poll et al
showed that female rats who had been injected with testosterone became more physically and sexually aggressive
describe oestrogen
promotes development and maintenance of female characteristics of the body ( eg breasts , adds femininity ) and regulates menstruation
-psychological effects eg pre menstrual tension, and female typical behaviours eg sensitivity and cooperation
research for oestrogen
albert and pepe
found that increasing oestrogen levels in pregnant baboons led to heightened cortisol production which assisted with the development in the foetus
describe oxytocin
released at birth and released when breast feeding . also affects female social behaviours such as mate selection and resting behaviours such as nurturing, acceptance and protection
research for oxytocin
van leengoed
-injected an antagonist of oxytocin after birth to inhibit oxytocin production . mothers showed a delay in maternal behaviours
describe the biological aspects of males and females
This explains differences between males and females in terms of their physical differences.
There are three types of physical characteristics referred to by biological theorists-
1- Chromosomal sex- every person has a 23rd pair of chromosomes which determine their biological sex. Male: XY Female: XX
2- The Gonads- these are the ovaries in females or the testes in males
3- Hormonal influences-
Male = androgens (testosterone) oxytocin
Female = oestrogen and progesterone oxytocin
These hormones result in different sexual characteristics.
Physical gender is determined by these three characteristics
describe The gene called SRY
Determines gender characteristics and is important for testis formation.
SRY stands for sex-determining region Y gene)
In the cell, it binds to other DNA and in doing so distorts it dramatically out of shape. This alters the properties of the DNA and likely alters the expression of a number of genes, leading to testis formation.
what are the two types of atypical chromosome patterns
turners syndrome
klinefelters syndrome
describe turners syndrome
Females develop with only one X chromosome. It affects 1 in 2,500 females.
They have an external female appearance but do not mature at puberty
physical characteristics
- no ovaries
- do not develop breasts
- short
- webbed neck
psychological characteristics
- higher than average verbal ability
- lower than average spatial ability
- difficulties relating to peers
describe klinefelters syndrome
Males have an extra X chromosome. It affects 1in 1,000.
They have a male appearance
physical characteristics
- little body hair
- some breasts develop
- undersized penises
psychological characteristics
- lack of interest in sexual activity
- tend to be passive and shy
- poor language skills and poor reading ability
- poor judgement and handles stress badly
describe hormonal influences , effects on males
Testicular feminising syndrome-
Pre-natal development in a chromosomally normal XY male is feminised.
Person has an insensitivity to androgens.
Internal reproductive structures don’t develop but normal- looking external genitals and a shallow vagina develop at birth. At puberty breasts develop but failiure to mensurate
describe hormonal influences , effects on females
andrenogenital syndrome
A chromosomally normal XX female is exposed to an excessive level of androgens at the critical period when sexual differentiation occurs.
Internal repreductive organs are unaffected but external structures resemble those of a male infant
internally females, externally male
what are other disorders of males and females
hermaphroditism
transsexualism
