Sc2220 lecture 2 2011

  1. 1. SC2220: Gender StudiesLecture 2: The Sex/Gender Distinction<br />Eric C. Thompson<br />Semester 2, 2010/2011<br />
  2. 2. Tutorials Announcement<br />Manual Registration is today and tomorrow.<br />Try to get it sorted out TODAY!<br />If you are not registered now, you will most likely have to enroll in one of the two 8am Tuesday tutorial slots. (I know that 8am is terrible and horrid, but it is the only time available. The only excuse we can entertain is that you have an NUS module timetable clash at 8am!)<br />If you have questions, please approach the instructor asap (at the break or after the lecture).<br />
  3. 3. Tutorial Announcement 2<br />Tutorial Session E2 (Even Weeks, Thursdays, 12-2pm) FIRST MEETING will be held one week early, due to the Chinese New Year Holiday.<br />The session will be held as follows:<br />Thursday, 2 to 4 pm<br />January 27<br />Sociology Seminar Room, AS1, #02-14<br />If you cannot attend, you need to contact the instructor and/or your tutor, Lynnette Chan, ASAP<br />
  4. 4. Outline: Today’s Lecture<br />Facts about Human Sex and Sexuality<br />Biology and Cultural Myth-making<br />When does Biology matter Socially?<br />
  5. 5. 1. A Few Facts about Sex<br />
  6. 6. What is so good about Sex?<br />Asexual (non-sexual) reproduction relies on mutation to create variety. <br />Sexual reproduction creates new combinations of DNA every time.<br />Variety: Speeds up evolution, allows for more rapid adaptation, allows for emergence of more complex organisms<br />
  7. 7. Asexual Reproduction (Example: Hydra)<br />Hydra are small creatures that live in water.<br />Hydra grow “buds” that drop off, grow large, and grow their own buds. Hydra are biologically immortal (they don’t age!).<br />(Note: This Hydra, a Mythical Greek Beast, is not what I’m talking about!)<br />
  8. 8. Sexual Reproduction (1):Sequential and Simultaneous Hermaphrodites<br />Clown Fish: Male to Female Sex Change<br />(Nemo’s deep dark secret?)<br />Wrasse: Female to Male Sex Change<br />Hamlet Fish: Simultaneous Hermaphrodites<br />(Take turns during extended, multiple mating sessions, lasting several days)<br />Banana Slug: Simultaneous Hermaphrodites<br />Prefers to mate with partner, but self-fertilizes if necessary.<br />
  9. 9. Sexual Reproduction(2):“Dedicated” Heterosexuals<br />Hoverflies<br />Homo sapiens sapiens<br />We are “dedicated” heterosexuals, in the sense that from birth onward we remain male or female.<br />Rabbits<br />
  10. 10. Human Sexuality Shapes Gender<br />If asexual, we would have no basis for “gender” at all.<br />If clownfish, gender would be an aspirational concept (men would aspire to one day become female).<br />Because humans are “fixed” (unchanging) as male or female from birth, we think of gender as a fixed attribute determined by our biology (even though it is not).<br />
  11. 11. Biology does dot Determine Gender.<br />Different cultures create many different interpretations of our biology (for example, two, three or more genders).<br />Different societies deal with biology differently (they put male and female bodies to use in different ways).<br />Gender is our cultural interpretations of and social practices associated with our biological system of sexual reproduction.<br />
  12. 12. The Sex / Gender Distinction<br />SEX: Is a biological construct. It is the product of biological processes (reproduction, DNA replication, mutation, selection, evolution, etc.).<br />GENDER: Is a social and cultural construct. It is the ways in which we organize our society, interpret, and give meaning to the fact that we are a sexually reproducing species.<br />There are many, many different ways to organize society around and many different ways to interpret our sexual reproductive biology.<br />
  13. 13. Sex at Different Levels<br />Biological Sex is not a simple binary<br />Genetic and Cellular Level<br />XY and XX Chromosomes<br />Hormonal Level<br />Testosterone, Oestrogen<br />Anatomical Level<br />Genitals, Secondary Sex Characteristics<br />See: Fausto-Sterling 2000, p.22<br />
  14. 14. Male, Female, and Other<br />Many types people are ‘intersexed’ individuals <br />They do not follow “normal” sexual development<br />Hermaphrodites (“five sexes”) only refer specifically to “uninterpretable” genitalia.<br />There are many other ways in which typically male and female characteristics can be ‘mixed and matched’; many are at all obvious.<br />Approximately 1% to 2% of all people born are “intersexed” in one way or another.<br />At least 1 of every 100 people is intersexed in one way or another (Fausto-Sterling 2000 estimates 1.7 per 100).<br />
  15. 15. “Intersexed” (Hermaphrodites)<br />A small percentage of all humans born are hermaphrodites; or “intersexed”<br />Many, many varieties of intersexed individuals (Reading: “The Five Sexes” only scratches the surface).<br />Intersexed individuals are ‘fixed’ by modern medicine; but this is not always helpful to the individuals involved.<br />Intersexed bodies are required to conform to cultural gender beliefs.<br />The Reclining Hermaphrodite<br />1st century BCE sculpture<br />See the Short Film<br />XXXY:<br />Intersex Genital Mutilation<br />
  16. 16. Human Sexes<br />For every 1,000 people:<br />491 are female<br />491 are male<br />17 are intersexed<br />1 other?<br />
  17. 17. Paths to Intersexuality<br />Some people have extra chromosomes: XXY, XYY<br />Others experience unusual development, for example:<br />In the womb, one set of processes “sexes” the body<br />“Masculinization” of the body*<br />Another set of processes “sexes” the brain<br />“Masculinization” of the brain.*<br />In the womb, sometimes a fetus experiences one process but not the other.<br />*For technical reasons, becoming female is considered the ‘normal’ developmental sequence; and “masculinization” is a deviation.<br />
  18. 18. Some Terminology<br />Intersexed (or “Hermaphrodite”) – Having both typically male and typically female genitalia<br />Transexual or transsexual – Crossing from one sex to another biologically (e.g. sex change)<br />Transgender – Crossing from one gender to another culturally (e.g. cross-dressing or “transvestite”)<br />Homosexual – Same sex sexual practice or identity<br />Heterosexual – Cross sex sexual practice or identity<br />A major problem is that our vocabulary for talking about these things is limited, vague, and inconsistent<br />
  19. 19. 2. Biology and Cultural Myth-making or How We Turn Ambiguous Biology into Cultural Truth<br />
  20. 20. Heterosexed Individuals<br />Most individuals are substantially “heterosexed”; they follow a standard developmental sequence (they are “normal” – in a statisical sense)<br />Even then, discounting ALL the many unusual cases. There is tremendous overlap in almost every respect between individuals who follow a standard female developmental sequence (i.e. women) and those who follow a male developmental sequence (i.e. men).<br />
  21. 21. Why are we obsessed with Biological Sex Differences?<br />They seem (are) more easy to observe – so they seem more “real” than socialization or culture.<br />They give us the comfortable illusion of permanence.<br />So, we look obsessively for biological sex differences, for example . . . <br />
  22. 22. “Sexing the Brain”*<br />Studies showing difference in brain structures: 13*<br />Studies showing no difference in brain structures: 95*<br />Question: Why focus on difference correlated with sex? What is the specific purpose of the research?<br />Left-handed & right-handed people exhibit as great or greater differences.<br />Focusing on sex/gender difference and highlighting the (minority of) studies that find differences, reinforces cultural sense of difference.<br />*See Fausto-Sterling, Sexing the Body (2000) Chapter 5<br />(This is among the supplementary readings)<br />
  23. 23. Ok, so there is a lot of misleading of scientific information, BUT men and women are still different in many ways, on average, right?<br />ABSOLUTELY TRUE!<br />Men are on average:<br />Faster<br />Stronger (esp. Upper Body)<br />Better with directions<br />Better with math (maybe)<br />Women are on average:<br />Less susceptible to illness<br />Better descriptive memory<br />Better at listening/recall<br />Better with language<br />But, what does “average” mean?<br />Is everyone pretty much average?<br />
  24. 24. Problem with Averages<br />Studies are repeatedly used to claim “men and women are different”<br />Average differences are always cited.<br />But, the range is almost never cited; without that, the meaningfulness of the “average” is useless.<br />“Even when scientists themselves are cautious… popular renditions of new scientific findings dispense with linguistic subtlety” (Fausto-Sterling pg.236)<br />
  25. 25. How big is the difference?<br />Example of a test of physical ability; emphasizing upper body strength.*<br />80%<br />FEMALES<br />20%<br />MALES<br />80%<br />In US Army physical tests: top 20% of women had the same average as bottom 20% for men.<br />(These statistics then get used both for and against women in the military)<br />
  26. 26. How much can you lift?<br />Udomporn Polsak (Female, Thailand,<br />Height 150 cm, Weight 53 kg):<br />Lifted 125 kg*<br />Tang Gonghong (Female, China,<br />Height 172 cm, Weight 120 kg):<br />Lifted 182.5 kg<br />Halil Mutlu (Male, Turkey,<br />Height 150 cm, Weight 56 kg):<br />Lifted 160 kg<br />Hossein Reza Zadeh (Male, Iran,<br />Height 185 cm, Weight 160 kg):<br />Lifted 262.5 kg<br />*All results for “Clean & Jerk”<br />2004 Olympics<br />
  27. 27. “Strong Masculine Bodies”<br />In many cultures, domestic work is considered more appropriate for women than for men.<br />In Samoa, Fafafini are considered excellent at domestic work because of their strong masculine bodies.<br />Bodies can be (and are) used and interpreted in many different ways.<br />
  28. 28. Turning Averages into Absolutes<br />Physical strength, especially upper-body strength is the most significant known difference between human males and females (aside from childbearing).<br />Most other differences have much greater overlap.<br />The science of averages is often turned into absolutes in popular discourse (which in turn guides public policy)… “Science” as myth-making… in modern societies, when we call something “scientific” it gains credibility.<br />In almost every case, the abilities of woman and men overlap.<br />
  29. 29. 3. Sex Differences that Matter in (Some) Social Contexts*Sexual Dimorphism*Reproductive Strategies*Sexual Competition*Hormones<br />
  30. 30. Sexual Dimorphism<br />Dimorphism: Two (“di”) forms (“morphism”)<br />Sexual dimorphism results from “natural” selection (and “sexual” selection) acting differently on males and females.<br />Cooperation (selection) between sexes; mate-selection (women choosing men and men choosing women)<br />Competition between members of each sex; men competing with men; women competing with women.<br />
  31. 31. Reproductive Strategies<br />In mammals (including humans), females are far more limited in the number of offspring compared to males.<br />This inclines females toward “quality” and males toward “quantity” in sexual reproduction and practice.<br />Females are more “selective” (and in this sense, more active in driving human evolution; Hrdy 1981)<br />
  32. 32. Sexual Competition<br />Sexual Competition (over access to mates) occurs between men and between women; NOT between men and women.<br />Men compete with other men to make themselves attractive to women (based on what women want; or what men think women want).<br />Women likewise compete with other women.<br />At the same time, groups of men and groups of women often cooperate.<br />
  33. 33. Some Consequences of Reproductive Strategies<br />Physical dimorphism (men being on average larger than women) is an outcome of competition between men.<br />Men’s larger size did not come about in order to physically dominate women; but in some cases it results in physical domination (violence or abuse).<br />Male competition focuses on sexual access to women.<br />Female competition focuses on access to the excess resources men produce (meat, money, etc.).<br />Some of the social and cultural consequences of these differences will be discussed later in the course…<br />
  34. 34. Testosterone (Hormone) Theory<br />Male dominance is often attributed to testosterone (e.g. Steven Goldberg, 1993).<br />Testosterone has effects that are important to understanding gender socialization – but they are oversimplified and exaggerated culturally.<br />The oversimplified, exaggerated testosterone explanations perpetuate gendered outcomes and are often inaccurate excuses for gender discrimination.<br />For example: Goldberg (1993) concludes that because testosterone (may) incline men to be more competitive therefore women should never compete with men.<br />
  35. 35. A Few Facts about Testosterone<br />Both men and women have testosterone.<br />Testosterone levels are affected by environment.<br />Levels of testosterone rise during competition (e.g. sports) – among participants and fans. The members and fans of a winning team have spike in testosterone after the game; testosterone levels in losing teams and fans drop.<br />Men’s testosterone levels fall after marriage and rise after divorce.<br />Boys have spikes in testosterone at various stages of childhood and adolescence.<br />Testosterone affects the body and emotional responses.<br />
  36. 36. Social Effects of Testosterone<br />Testosterone makes boys more “aggressive” (agitated).<br />Boys and girls respond equally to physical/aggressive activities, but boys are more likely to initiate them.<br />Aggression contributes to different play styles.<br />Different play styles contributes to self-segregation by gender (boys play with boys, girls play with girls)<br />Segregation leads to different socialization (girls learn from each other ‘how to be girls’; boys learn from each other ‘how to be boys’)<br />The socialization is responsible for the greatest differences; the testosterone is a “catalyst” but not a “cause” (Testosterone would have no effect in the absence of socialization processes).<br />
  37. 37. Beyond Testosterone<br />Testosterone is just one example of the complex interactions of biology (hormones), society and cultural contexts.<br />Interactions between sex (biology) and gender (society, culture) are always similarly complex.<br />Correlation between a biological fact and a social and cultural one can never be taken as proving that one causes the other.<br />Reducing gender to biology is myth-making; not science.<br />
  38. 38. “Hormone drives sexy women to infidelity – says study”*<br />Based on research by Norman Li at SMU<br />Reported world-wide (France, China, Singapore, etc.)<br />How do we interpret this report/finding?<br />
  39. 39. Possible Misinterpretations<br /><ul><li>Oestradiol (the hormone) makes women ‘horny’ and seek sex… (wrong)
  40. 40. Apparently NOT; Li and Durante specifically found that the hormone is associated with looking for a new (and presumably better) LONG TERM partner and NOT with seeking casual sex.
  41. 41. The finding is “significant”; therefore very important in understanding infidelity… (maybe, maybe not)
  42. 42. “Significant” in statistical, scientific language means “probably not just an effect of chance”
  43. 43. But, there are many factors involved in infidelity (social, cultural, environmental as well as other biological factors).
  44. 44. While the effect of this hormone may be statistically significant, it may not be substantially significant. (Its significance may be tiny compared to all the other factors involved… that is an open question).</li></li></ul><li>Oestradiol “Explains” Infidelity?<br /><ul><li>Example: “The Quiet American” (by Graham Greene)
  45. 45. Set in 1952; Older British Journalist in Saigon has beautiful young Vietnamese mistress (Phuong), who dumps him for a young American man.
  46. 46. Is the plot “explained” by Phuong’s high levels of Oestradiol?
  47. 47. Can we discount colonialism, social class, social and cultural beliefs about gender, nationalism, race, ethnicity, politics, etc.?</li></li></ul><li>Final Thoughts…<br />How have this lecture and reading changed your understanding of human sex and sexuality?<br />Is anything here new to you?<br />What questions do you have?<br />Bring them to tutorials!!!!!<br />
