Final (Ch 10, 11, 15, 16) Flashcards
Definition of Sex
- biological femaleness or maleness or intersex as indicated by genes, hormones, and physiology
- genetic sex is more complicated than chromosomal sex
- biological sex- a set of biological and reproductive characterisitcs to categorize individuals as being male, female, or intersex
Definition of Gender
- the psychological experience of femaleness or maleness
- an emergent property of the biological and sociocultural factors that influence gender identity and gender roles
SRY gene and its implications
- the gene that determines which gonad differentiating genes are expressed and found on the Y chromosome
- In a typically developing XY male the presence of SRY overrides the ovary promoting genes present on the X chromosome which results in male gonads, androgens at puberty, and a male-looking body
- In a typical developing XX female where there is no SRY gene and ovary-determining genes present, the ovaries will develop and secrete estrogens at puberty, resulting in a female looking body
- If SRY is expressed on an X chromosome in XX female, testes will develop, and individual will be phenotypically male
- If SRY is silent on a Y in XY male, ovaries will develop, and the individual will likely be phenotypically female
Gender role and gender identity
- Aspects of femininity, masculinity, and gender diversity learned via socialization and culture, and enacted in our appearance, behaviors, and beliefs, as well as how our structures and systems are organized, will influence an individual’s gender identity
- Gender role is informed by gender schemas and stereotypes or attitudes about what are acceptable behaviors, attributes, and positions in society for men, women, and gender diverse people
- gender identitiy- internal experience of femaleness, maleness, neither or other(s)
- gender role- the set of social and behavioural norms that are considered socially appropriate for individuals of a specific sex in the context of specific culture
Evolutionary psychology theoretical perspective on gender and sexuality
- understand g/s differences in sexuality as arising from evolutionary processes aimed at maximized reproductive fitness
- parental investment theory –> differences are due to potential reproductive outputs, which give rise to differences in gendered psychological processes and behaviours aimed at maximizing the likelihood that their offspring wil survive and reproduce
- Females can produce limited number of children = more conservative physiologically = lower sex drive, less sexual partners, want committed relationships
- Males have greater capacity to produce more offspring = less conservative = higher sex drive, more casual sex, preference for partners who exhibit characteristics associated w youthfulness
- traits associated w high RO are maintained via natural selection
Social learning theory theoretical perspective on gender and sexuality
- gender differences in sexuality are the result of observational learning through media for example
- female sexual fluidity –> female sexuality is more malleable than male sexuality in reeponse to cultural influences
Social structure theory theoretical perspective on gender and sexuality
- g/s differences in sexuality (in particular to mate preference) arise bc of gender binary division of power that emerges from a gender stratified workforce where men control resouces
- men are breadwinners and women are caregivers –> dictate appropriate conduct for men and women resulting in further gender differentaited behaviours
- Men are expected to take agentic roles, and be assertive, independent, and dominant
- Women are expected to take on communal roles by being relationship oriented, submissive, and dependent
- Gendered power inequality often manifests as the privileging of men’s sexuality, sexual objectification and dehumanization of women, and woman prioritizing the acquisition of long term means with resource is because they have limited means to provide for themselves
Gender Similarities Hypothesis
- developed by Janet Hyde
- proposes that women and men are more similar than different for most psychological variables
- exceptions include psychological factors related to physical capacities like velocity and distance, special ability, aggressive behaviors, and in certain aspects of sexuality
g/s differences in masturbation, numbers of partners, attitudes towards casual sex, and erotica use
- men report greater sociosexuality–> willingness to engage in sexual activity outside of commited relationship (more permissive attitudes toward and actual behaviour of casual sex) –> may be reflective of males greater reproductive outcomes and lower costs
- femlaes might strategically engage in casual sex at times of high fertility by choosing men w high reproductive fitness
- women’s interest in sex may fluctuate w menstrual cycle –> greater interest during ovulation
- gay men have similar attitudes and behaviour as straight, but may have more sex bc they are having sex w men w less conservative attitudes
- Straight men show significantly greater preference for youthful partners and significantly greater sexual jealousy or emotional upset then gay men –> likely due to bias towards females reproductive age
- Lesbian and heterosexual females did not differ in many aspects but lesbian women report greater interest in visual sexual stimuli , and heterosexual woman prioritized main characteristics associated with the ability to provide resources like social status
g/s differences in sexual orientation
- show large g/s difference
- women are less likely to report exclusive different gender attraction
- women more likely to identify as bi, and report sexual attraction to both genders, and to have same gender contact
- as womens sex drive increases, so does their sexual attraction to both men and women –> no correlation seen in men
- cis female more likely than cis men to report some degree of same-sex attraction (more fluidity)
- bisexual and lesbian women are more likely to change identities overtime than gay or heterosexual men
g/s differences in patterns of sexual response
- Women and men differ in two aspects of sexual response: specificity of sexual arousal and sexual concordance
- Men’s patterns of sexual arousal and genital response closely correspond to their stated sexual attractions to a man or woman, but heterosexual women’s do not
- Although women who are exclusively heterosexual report greater sexual arousal to stimuli depicting men than women, they also show genital responses to sexual stimuli depicting women
- For women awareness of genital arousal may not be a significant factor in determining their desire for a partner –> women experience automatic genital response to sexual stimuli; the lower concordance may often be produced by low reports of feeling sexually aroused
- Reporting biases and double standards may explain why studies repeatedly find that women’s minds and bodies are less in sync than in men
g/d differences in reporting biases
- Men’s and women’s self-reports about their sexuality may be biased by desires to conform to gender norms
- Men tend to over report their partner numbers and women tend to under report which is consistent with a double standard whereby more liberal sexual attitudes and behaviors are tolerated in men but discouraged and woman
Diversities of Sexual Development (DSDs)
- congenital conditions in which the development of anatomical, gonadal, and/or chromosomal sex is atypical
- true hermaphroditism refers to having both female and male reproductive organs, and is very rare in humans
- DSDs often identify as intersex
- Sex chromosome variations: Klinefelter’s, Turner’s
- Sex hormone variations: congenital adrenal hyperplasia, androgen insensitivity syndrome, 5-alpha-reductase deficiency
- Penile traumas and congenital variations
Klinefelter’s Syndrome (XXY)
- most common sex chromosome trisomy disorder –> phenotypically male
- results from having two copies of the androgen receptor gene present on the x chromosome
- impaired feedback signalling to HPA results in high level of FSH, and lower level of testosterone
- usually not diagnosed till puberty –> gynecomastia, small testes, smaller penis, low testosterone, tall stature, compromised fertility
- many report low sexual desire, later onset of masturbation
- usually identify as males and are attracted to females
- typical treatment includes testosterone supplementation
Turner’s Syndrome (XO)
- phenotypically female –> identify as female and intersex
- short stature, broad and widely spaced nipples, underdeveloped physical characteristics, and infertility
- often treated w growth hormones in children, hormones to induce and hormone replacement therapy through adulthood
- first masturbation and sex are typically reached at later stages
Congenital Adrenal Hyperplasia
- autosomal recessive genetic disorder affecting cortisol synthesis that most commonly results in increased androgen production
- Individuals are typically exposed to elevated levels of androgens produced by their adrenal glands prenatally, and this exposure during the 6th week of gestation affects development of female fetus, causing varying degrees of virilization –> larger clitorises, partially fused majora, shorter vaginal length, incomplete differentiation of vagina and urethra
- the development of internal reproductive organs is typically unaffected in females
- Genetic males appearance is mostly unaffected –> often diagnosed at birth, but sometimes diagnosed a puberty when it may present as early onset of puberty accompanied by penile or clitoral enlargement
- half of women present w POS, which can lead to infertility, and many have compromised sexual function, pain and report lower arousability
- most women are heterosexual but some correlation btwn prenatal androgen exposure and degree of same-sex attraction
- girls might show lower nuturance and empathy and higher aggression (opposite for boys), and more interest in male-typical occupations
- dexamethasone decreases chance of passing on to offspring
Androgen Insensitivity Syndrome
- X-linked recessive disorder where individuals born with XY chromosomes develop female physical characteristics but during fetal development, testes will develop under the influence of SRY, but generally do not descend
- As individuals develop, testes secrete typical levels of androgens but mutations in androgen receptor genes prevent the body from responding to the hormones, but they do respond to estrogens leaning to female-typical phenotype
- Individuals with partial AIS (PAIS) generally have intermediate male and female typical characteristics with differing degrees of general virilization
- Individuals with complete AIS (CAIS) have genitals that appear typically female, although the vagina may be shallower
- Most are assigned female at birth and are raised as girls, are heterosexual, and identify as women
5-alpha reductase deficiency (5-ARD)
- results from mutations of the gene that encodes for 5-alpha-reductase 2- which is an enzyme that converts testosterone to DHT
- Individuals have usually undescended testes and typical levels of testosterone, so their internal reproductive organs are male, but because of the enzyme deficiency, external genitals develop as female typical (these tissues require DHT to virilize)
- Typically assigned female at birth and raised as girls until puberty
- When testosterone increases at puberty, virilization continues: the testes descend, the scrotum becomes pigmented, and the clitoris enlarges to resemble a small penis
- At this point most individuals will identify as men and are sexually attracted to woman
- Individuals may choose to undergo surgery to correct penile anomalies and may also choose hormone therapy
Penile Traumas and Congenital Variations
- Some individuals are raised in a gender role different from their chromosomal sex for reasons other than a genetic disorder
- Physical developmental anomalies unrelated to sex chromosomes or sex hormones, search as penile agenesis, or cloacal exstrophy, resulting in a genetic male not having a penis
- For some individuals gender identities more strongly associated with genetic and hormonal sex than the assigned gender –> both nature and nurture play crucial roles in shaping gender identity
Gender Development in Childhood
Gender development involves 3 related processes
- Detecting gender- being able to identify the similarities and differences between females and males
- Having gender- recognizing in oneself characteristics shared by either boys or girls or both
- Doing gender- matching one’s gendered behaviour w female or male gender stereotypes
- By age 1 majority of babies can detect gender, by two and three most children can identify what gender they have but they believe this to be a superficial characteristic, around age three to four children understand that gender is an inherent characteristic (gender constancy)
- Doing gender or behaving in stereotypic girl or boy ways emerges between the ages of 5 to 7
Factors that shape a childs sense of gender identitiy and gender roles
- gender roles are imposed and babies’ behavior is interpreted through gendered lens
- Male and female children are temperamentally different: boys are notoriously more active, engaging in rough and tumble play and preferring active toys, whereas girls are typically less active and prefer playing with dolls and emulate nurturing
- Some believe that toy preferences (one expression of gender role and identity) are slowly the result of gender socialization, a process thought to be mediated by two forms of learning
- Observational learning- children watch and emulate the behaviors and choices of other children and adults
- Operational learning- gender conforming behaviors are reinforced and gender nonconforming behaviors are punished and children adhere to playing with toys that are prescribed for the male or female role in childhood
Gender variation in Childhood and Adolescence
- Not all children adopt the gender identity or role strongly associated with their birth
- There is controversy surrounding the diagnosis of gender nonconforming children with gender dysphoria and treatment options
- The vast majority of gender nonconforming children desist in their gender dysphoria and grow to be happy and well-adjusted adults –> clinical practice of encouraging children to accept their birth sex and express their gender without medical intervention is the preferable approach to more irreversible medical interventions such as gender affirming surgeries
Trans Identiities
- Birth-assigned males who identify as women are referred to as trans women, and birth-assigned females that identify as men are referred to as trans men
- Sometimes terms male-to-female (MTF) and female-to-male (FTM) are used
- Some people eschew gender binary altogether referring to a concept of a continuum of fluid gender, or choosing to identify as genderqueer
Transitioning: Psychological and Physical Examination
- The first part of the process is psychological and physical evaluation by health care providers to diagnose gender dysphoria and rule out other mental concerns that might impact one’s experience and understanding of their gender
- This is especially relevant to those on the spectrum as there is significant overlap between gender dysphoria and spectrum disorders
- group therapy to connect and receive support
- need to ensure decision is only motivated by a strong desire to match physical attributes to their gender
