LECTURE Flashcards
Vasey (instructor) research uses __
triangulate: different methods for same hypothesis
what is sexual attraction
what is receptivity
what is proceoptivity
increased sexual interest in a target
willingness to engage in sexual activity
active solicitation of sexual activity
the subjective perspective on sexual orientation rejects __ and rejects __
idea of objective knowledge (truth) is attainable thus anti-empirical and anti-radical (e.g., Queer Theory)
psychological and behavioural sex differences/orientation have any biological component
the subjective perspective holds all psychological and behavioural differences are social constructs thus is intersubjective thus __
knowledge always restricted to culturally and historically specific intersubjectives (limited to emic vs etic viewpoint)
-emic=perspective of insider
-etic=perspective of outsider
what is queer theory
variant of social constructionism, which claims special expertise in relation to sex differences and sexual orientation
-seeks to subvert whatever is deemed “normal”
-political strategy
as social constructs, sexuality is infinite, unstable and arbitrary thus __
any universal categories we create to characterize sexuality is illusory (e.g., male typical vs female typical)
cannot meaningfully compare culturally and historically specific intersubjectivies thus __
are equally valid (cultural relativism)
those with socio-political power controls __
what counts as knowledge and truth (episteme)
-“power knowledge”, which relates to Queer theory
what is the goal of Queer Theory
push “queer” political agenda by disrupting what counts as normative knowledge to create confusion (obfuscation)
-believe language policing will cause us to think and behave differently thus eliminating oppression caused by categories
what is the Euphemism Treadmill
offensive words replaced with non-offensive words
-e.g., homosexual replaced with gay
sexual orientation categories are __ characterized by __
objectively real (natural kinds)
objective characteristics (intrinsic properties)
-will emerge regardless of subjective beliefs and historical/cultural context
sexual development begins with __
fusion of two anisogamous (unequal) gamates
gamates are __ sex cells meaning __
hapoid
they contain single set of 23 chromosomes
fusion of two gamates produces __, that develops into a new individual
these cells contain __
diploid cell (zygote)
46 chromosomes (23 pairs: 22 pairs of autosomes + 1 pair of sex chromosomes)
the developing XX and XY embryos have 3 characteristics, what are they
- one bipotential embryonic gonad
- one bipotential embryonic gential (genital ridge)
- two embryonic reproductive tracts (Mullerian duct system and Wolffian duct system)
Y chromosomes contain __ and at about 6 weeks post-conception, this triggers __
SRY gene
embryonic gonadal tissue to develop into testes
if the SRY gene is absent, __ direct embryonic gonadal tissue to develop into __
DAX-1
ovaries
developing embryonic testes produce __ and __
testosterone
mullerian inhibiting hormone (MIH)
at about 8 weeks post-conception, what four things can occur
- MIH causes mullerian duct system to regress
- T promotes development of Wolffian duct system into male reproductive tract
- in absence of T, wolffian duct system regresses
- in absence of MIH, mullerian duct system develops into female internal reproductive tract
during embryonic development, __ exists
this has two ridges of skin called the __ and these folds surround the __
single bipotential (homologous) protogenital
urethral folds (labia minor or shaft of penis)
urogenital sinus (urinary and genital tracts)
urethral folds meet anteriorly to form __
surround the urethral folds is __
genital tubercle (embryonic glans)
genital swelling (labia majora or scrotal sack)
what occurs around 10 weeks post-conception
testosterone causes fetal genital tissue to develop into male external genitalia (penis, scrotum)
in absence of T, fetal genital tissues develop into female external genitalia (clit, labial folds)
what are the two types of gamates produced by gonads
they are __, meaning they differ in size and function, explain
eggs and sperm
anisogamous (unequal)
eggs are large, nutrient rich and immobile whereas sperm are small, nutrient poor and mobile
in biological terms, how is sex defined
production of one type of gamete or the other thus sex refers to reproductive strategies
-strategies represent potentials that are not necessarily realized
females are sex defined by __ and males are sex defined by __
thus sex is __ by sex chromosomes
egg production which occurs in ovaries
sperm production which occurs in testes
determined (not defined)
structures that arise from organizational effects of gonads during development are __ but do not define sex
phenotypic markers that denote sex
-include gonads, internal reproductive tracts and genitals
primary markers that denote sex develop __
around 10-18, humans undergo __
in utero
secondary sexual development (puberty)
the second divergence in morphology evolved to __
enhance sexes ability to behaviourally enact one of two broad reporductive strategies:
1. be attractive (female evolutionary strategy)
2. be dominate (male evolutionary strategy)
not all species have a sex, give an example
prokaryotes
-unicelluar organisms lacking nuclei and mitochondria
some species have one sex, give an example
some species are simultaneously two sexes, give an example
some species are sequentially two sexes, give an example
no species has more than two sexes***
whiptail lizards (cloning)
corpse snail
clownfish
what is intersexuality sometimes referred to as
Disorders of Sexual Development (DSD)
how sex is conceptualized varies __
cross-culturally based on external morphological criteria
no change in how we choose to define sex is going to change fact that __
gamete production is an objective and binary biological/reproductive phenomenon, not a socially constructed one
intersex conditions are categorical, explain
relative to each other, they are not expressed as continuous gradient from male to female
-gamete production is completely dichotomous thus sex does not exist on continuum
what is the confirmation bias
tendency to search for, interpret, favor and recall information that confirms or supports one’s beliefs and values
what is motivated reasoning
tendency to make decisions that are desired (emotionally-motivated) rather than those that are evidence-based
what is gender
belief system used to construct categories based on concepts of masculinity and feminity
-anything can be “gendered” by attributing masculine or feminine characteristics to it
