Exam 5 Flashcards
What are the three primary dimensions of sexual orientation?
Identity, motivation, and behavior.
Sexual identity: what is it? What are some examples of sexual identities? What are the psychological experiences that can be associated with one’s sexual identity (positive or negative)?
Sexual identity: how one describes their sexual orientation.
- Incorporate traits, behaviors, values of adopted identity into self-concept
- Many experience positive feelings about central, important identities
- Internalized homophobia can occur due to stigmatization
- Some experience uncertainty, fluidity, or do not identify with a sexual orientation label
What is sexual desire (“lust”)? Why might it be adaptive?
Sexual desire (“lust”): urge to engage in sexual activities.
- Involves physiological arousal
- Regulated by gonadal hormones, neurotransmitters (e.g., oxytocin)
- Adaptive: motivates cross-sex unions for reproduction
What is love, and how does it differ from lust? Why might it also be adaptive?
Love (attachment): strong feelings of affection, attachment that go beyond mere warmth
- Motivates directed attention toward specific cherished other
Compare and contrast passionate vs. companionate love.
Passionate love: dopamine, norepinephrine facilitate reward, arousal
Companionate love: oxytocin, vasopressin facilitate intimacy, bonding
Describe the pair-bonding system and why it might be evolutionarily advantageous.
Pair-bonding system: two adults of a species remain bonded for producing and raising offspring
Evolutionary function of love?
Biparental care = greater chance of survival of highly dependent offspring
Are the three dimensions always aligned; stable? Why or why not? Defend your reasoning from lecture. What does this tell us about sexual orientation?
No, same-sex desire does not always predict same-sex behavior or identity.
- What goes on during the “awareness” stage? What is “unexplored commitment” and why might this happen amongst heterosexuals in particular at this stage? (phase model of sexual identity development)
Awareness
- feeling different from others
- realizing sexual orientation can vary
- Confusion, fear for non-heterosexuals
- Heterosexuals often lack thought about own identity (“unexplored commitment”)
- What goes on during the “exploration” stage? What is “identity uncertainty” and what are the two reasons why it might occur amongst some sexual minority individuals during this stage? (phase model of sexual identity development)
Exploration of feelings, similar others, etc.
-
Identity uncertainty amongst some sexual minorities
- If exploration fails to produce clarity
- If resistance to same-sex sexuality
- Heterosexuals may explore but not necessarily (can bypass)
- What goes on during the “deepening and commitment” stage? What are some common experiences amongst sexual minorities in this stage? (phase model of sexual identity development)
Deepening and commitment
- greater self-knowledge
- greater commitment to identity
- Sexual minorities: increased involvement in LGBTQ+ community
- Heterosexuals: consider privilege?
- What goes on during the “integration / synthesis” stage? (phase model of sexual identity development)
Integration/Synthesis: sexual identity integrated into one’s self-concept
- What challenges do asexuals face that heterosexuals or sexual minorities may not face? (phase model of sexual identity development)
Asexuals: similar, but somewhat unique, phases
- Awareness as identity uncertainty – lack of language, pathologizing of experience
- Distinct “discovery of terminology,” legitimizing and adopting asexual identity
- Level of importance of asexuality, “outness” can vary
Intersection of multiple oppressed identities can complicate sexual identity development
- Denial and erasure of same-sex sexuality
What is LGBTQ+ conversion therapy? Why was it developed, and is it credible? What are the mental health outcomes associated with undergoing conversion therapy?
Conversion therapy is the use of psychological or spiritual methods to try and “fix” someone’s sexual orientation to be the “normal” sexual orientation of heterosexuals. It was developed under the bias and discrimination against non-confirming sexual orientation. It is not credible at all, there is no evidence that it “fixes” anyone’s sexual orientation. Some of the mental health outcomes associated with undergoing conversion therapy for LGBTQ+ clients include experiencing shame, anger, anxiety, depression, and suicidal thoughts. LGBTQ+ youth are nearly twice as likely to attempt suicide if they underwent conversion therapy.
To what extent is sexual orientation heritable? What does this mean? (biological theories of sexual orientation)
Moderately heritable especially in men
- Strong evidence for genes
Men h2=14-67%; women h2=8-30%
What is the neurohormonal approach? What predictions does it make about hormone exposure during fetal development and sexual orientation? (biological theories of sexual orientation)
Neurohormonal approach: fetal exposure to sex hormones affects development of sexual orientation.
- Exposure to testosterone = attracted to females
- Exposure to estradiol = attracted to males
- Evidence in animals, not as much in humans
Explain the maternal immune response to Y-linked proteins. How could this explain sexual orientation in males, in particular, the increasing likelihood of identifying as gay as the number of older biological brothers increases (fraternal birth order effect)? Can this phenomenon also explain women’s sexual identity? (biological theories of sexual orientation)
Fetal exposure to maternal antibodies?
Y-linked proteins elicit immune response; grows with every son; affects male fetal development
Fraternal birth order effect: positive correlation between number of older biological brothers and a man’s own likelihood of identifying as gay.
- 33% chance increase per older brother
- Do not see the same pattern amongst women
- Mothers of gay sons have elevated antibodies
What explanation does the alliance formation hypothesis provide for same-sex sexuality? What evidence do we have—is it supported in humans? (evolutionary theories of sexual orientation)
Same-sex sexuality is evident in 450+ animal species (33 primates).
Alliance formation hypothesis: same-sex sexual activity promotes beneficial friendship bonds between unrelated primate pairs (e.g., reciprocal altruism).
- Supported in non-human primate studies
- Speculative application to humans
According to kin selection theory, what role could same-sex oriented males play in the reproduction of close relatives? What evidence do we have? Does it explain females as well? (evolutionary theories of sexual orientation)
Kin selection: benefits of same-sex-oriented male relatives (e.g., childcare) outweigh costs of not reproducing
- Supports reproduction of close relatives
- Not supported in Western cultures
- May explain fa’afafine of Samoa –
- Greater altruism toward nieces, nephews
- Does not explain female sexual orientations.
What is meant by the fecundity hypothesis? What evidence is there for this? Can it explain males, females, or both? (evolutionary theories of sexual orientation)
Fecundity hypothesis: genes for same-sex sexuality may get passed down if their relatives are more fertile.
- Greater fecundity amongst mothers, aunts of gay (vs. heterosexual) men
- No one really knows why
- Does not explain female same-sex sexuality
What are the primary predictions of tipping point theory? How could it explain the persistence of sexual orientation in the human species? (evolutionary theories of sexual orientation)
Tipping point theory: alleles coding for same-sex orientation overlap with personality traits that enhance reproduction
- Having a few of these alleles enhances reproductive success (more partners)
Some support: communal men and agentic women have more partners
- “Tipping point” where additional alleles can change sexual orientation
What is the biobehavioral model? What social explanation can it provide for same-sex sexuality?
Biobehavioral model: same-sex sexuality can develop in sex-segregated environments with a high degree of proximity and intimacy
- “Passionate friendships” indistinguishable from romantic love
- Increased oxytocin can foster sexual arousal, attraction
What sex differences do self-report measures reveal regarding sexual behaviors and attitudes? How do these compare to brain imaging studies?
Most self-report effect sizes zero to small except:
- Casual sex: frequency, positive attitudes (men)
- Masturbation, pornography use (men)
- Frequency of same-sex experiences (women)
- Favorability toward sex with emotional commitment (women)
Brain imaging studies show no difference in responses to erotic stimuli
