Gender descriptions Flashcards
Sex
-biological differences between males and females including chromosomes, hormones and anatomy
-determined by chromosomes: men=XY, women= XX
-these chromosomes influence hormones and anatomy
-therefore sex is innate and the result of nature
Gender
-psychological and cultural difference between males and females including attitudes, behaviours and social roles
-refers to a persons psychosocial status as either masculine or feminine
-influenced by social norms and cultural expectations
-gender partly influenced by environment, so partly due to nuture
Batista family
(gender can be fluid)
-4 children who identified as girls at birth
-when reached puberty, vaginas closed and grew testes and penis
-genetic disorder where during prenatal development, they missed the introduction of dihydrotestosterone which externalises male genitalia
-at puberty, dihydrotestosterone was produces and true sex was revealed
Intersex
-where children are exposed to hormonal imbalances in the womb, so their genitals appear neither male nor female
-parents are encouraged to opt for surgery to make sex clear
-1.7% are intersex and most are unaware of the condition until puberty or find themselves infertile in adulthood
Sex role stereotypes
-set of beliefs and preconceived ideas about what is expected or appropriate for males and females in a given society
-they are communicated and reinforced by media
-parents, peers and media are agents of socialisation and support stereotypical expectations
-some stereotypes have no basis eg. women love shopping, others supported by bioogical brain differences eg. women better at multitasking as they have thicker corpus callosum
-Ingalhalikar study
Ingalhalikar study
-scanned 949 men and women brains using MRI
-mapped connections if different parts of the brain
-found women have better connection between hemispheres
-mens brains show more intense activity in individual parts especially cerebellum
-concluded female brain wired to cope with multiple tasks at once whereas male brains focus on one more complex task
The Bem Sex Role Inventory (BSRI)
Bem
-first systematic attempt to measure androgyny using a rating scale of 60 traits (20 masc, 20 fem, 20 neutral) to produce scores across 2 dimensions (masculinity-femininity and androgynous-undifferentiated)
-rate on scale from 1-7 where one is never true for me and 7 is always true
-numerical scores for masc and fem items are added and then given a score for masc, fem or andygynous
-masc items: athletic, ambitious, aggressive
-fem items: affectionate, gentle, warm
-neutral items: conscientious, friendly, reliable
Evidence for stereotyped behaviour
Smith and Lloyd
-when playing with children, adults provided children with stereotypical boys and girls toys based on appearance
Androgyny
-displaying a balance of male and female characteristics in one’s personality
-Sandra Bem- high androgyny is associated with psychological wellbeing as better equipped to adapt to a range of situations
Role of chromosomes
-found in nucleus of cells and carry genetic info in the form of genes
-23 pairs, the last are the sex chromosome xx=female xy=male
-made DNA, genes are short sections of DNA that determine characteristics
-all normal egg cells have an X chromosome, half sperm carry X, half Y
-the Y carries a gene called SRY (sex determining region Y) which causes testes to develop and produce androgens
Role of hormones
-chromosomes determine a persons sex but hormones can influence gender development
-prenatally hormones cause development of reproductive organs
-at puberty hormonal activity triggers development of secondary characteristics such as pubic hair, breasts
-usually produce same hormones but in different quantities eg. males produce androgens such as testosterone, females also produce testosterone but less of it
-testosterone, oestrogen, oxytocin
Testosterone
-type of androgen that is produced in testes and small amounts in ovaries
-produced at 8 wks gestation and controls development of male sex organs
-Nanne Van de Poll found female rats who were injected with testosterone were more aggressive than normal femal rats
Oestrogen
-primary female hormone which plays role in menstrual cycle and reproductive system
-suggested that it causes high emotions and irritability during the menstrual cycle (PMS)
-PMS has been used in defence of crimes such as shoplifting and murder
-some researchers dispute PMS existence
Oxytocin
-hormone that causes the uterus to contract during labour and stimulates lactation
-reduces stress hormone cortisol, so women can bond with baby after birth
-in stressful situations, cortisol dampens the fight or flight and triggers tend and befriend
-doesn’t happen in men as testosterone dampens the effects of oxytocin
-men produce less of this hormone
Atypical sex chromosome pattern
-any sex chromium pattern that deviates from the usual XX or XY
