individual differences - gender Flashcards
Gender refers to:
the psychological or cultural aspects if maleness or femaleness.
Sex refers to:
the biological aspect of an individual for example a child’s sex is identified at birth by its genitals.
Gender differences:
(male) aggression, determined, sharp-witted (female) cautious, emotional, warm.
Biological factors:
chromosomes, hormones, brain differences.
Environmental factors:
social learning theory (Bandura, 1961), biosocial theory (Smith & Lloyd, 1978), cognitive development theory (Kolberg, 1966) and gender schema theory (Bem 1981).
Chromosomes are:
tiny, thread like structure inside most cells of every organism, or living thing, carry info unit genes. Sex is determined by chromosomes. Chromosomes carry info about the organism in units called genes. When living organisms reproduce, they pass their genes into their offspring.
Y chromosomes carry:
H-Y antigen causes embryonic gonads to transform into testes
Chromosomes crucial in:
sex development in pre-natal stages
Batista boys:
were born and raised as girls but at puberty became male due to mutated chromosome gene where the body misses a critical chemical step, so the external anatomy doesn’t change. Born with XY chromosomes (male) due to delayed development in womb born female. Testosterone during puberty triggered development.
Klienfelter syndrome:
male sex chromosome abnormality. Male inherit 1 or more X chromosomes making their genotype XXY/XXXY. Several cases males: higher pitched voices, asexual or feminine bodies, breast enlargement and little facial and body hair. Testes and prostate glands small producing small amounts of testosterone. Normal sexual functions, including erection and ejaculation
Hormones are:
chemicals that affect the development of sex organs and activity. Both sexes produce same hormones female oestrogen and progesterone and male androgen and testosterone.
Hormones affect:
primary sex characteristics (external appearance vag, penis horm imbalance = unclear) secondary at puberty (breast enlargement, hair, deep voice).
AIS is:
when a person who is genetically male ( 1 X and 1 Y chromosomes) is resistant to male hormones (called androgens).
Hormones influence:
brain development in womb. Difference in ‘brain road maps’ explain why males outperform females on certain mental skills whereas females have the edge in other skills. Women have more connection L to R handing logical thinking and intuition whereas male front and back motor and spatial skills.
David Reimer:
was born a boy XY, 7 months malfunction circumcision burnt off his penis. Turned into a girl Brenda nurtured as a girl (girls clothes, dolls, makeup). As she grew up tomboy preferring twin brothers toys. At age 13 found out truth had reconstructive surgery at 14 named David was happier male. Case shows significance of biological approach to gender and the importance of chromosomes on ones gender identity and nature more important than nurture.
