 Sexual orientation prohibited ground for
discrimination
Research
 Adams, Wright and Lohr (1996) gave test to
measure homophobia to male college students
 Group 1: high scores
 Group 2: low scores
 All participants hooked to plethysmograph
 Watched film clips of hetero, gay and lesbian sex
 Group 1: 54% had increased penile errection
 Group 2: 24% had increased penile circumference
Gender Differences
 In an experiment heterosexual and homosexual
males and females watched videos of
a)
b)
c)
d)
e)
f)
Heterosexual sex
Male gay sex
Lesbian sex
Nude males
Nude females
Bonobos having sex
 The participants were hooked to a
plethysmograph
 Aasked to report verbally when aroused
Gender Differences
 Heterosexual males became aroused when
watching
 Heterosexual sex
 Lesbian sex
 Nude females
 Homosexual males became aroused when
watching
 Male homosexual sex
 Nude males
 100% concordance between plethysmograph
results and self report
Gender Differences
 Both heterosexual and homosexual women
were aroused by all the videos
 According to the plethysmograph
 Self reports were at odds with objective data
 Women are not aware when they are aroused
 Another gender difference:
 More women self-label bisexual than males
 More women switch sexual orientation over their
life times
Development of Sexual Orientation
 Several possible ways to acquire sexual
orientation
 Basic human needs shared by all
 Sensual/sexual fulfillment

 Cannot look for THE cause
 INTERACTIONS

Development of Sexual Orientation
 Prenatal factors
 Sexual differentiation and innappropriate
hormones
 Severe maternal stress (animal studies)
 Maternal stress is retrospective
 No tally of stressed expectant mothers who had
heterosexual children
Development of Sexual Orientation
 Prenatal factors
 Very high levels of estrogen
 Lesbian offspring
 Birth order (Canadian):
 Males with several older brothers
 2D:4D finger-length ratio
 Handedness
 No agreement in different studies,
contradictory data
Development of Sexual Orientation
 Brain differences
 Hypothalamus
 Small sample
 Non-comparable
 Cause of death
 Difference due to orientation or to disease and its
treatment?
 Other differences found, but all in adults after the
fact (chicken/egg)
 Endocrine imbalance
 No differences found
Development of Sexual Orientation
 Learning:
 Possible in some cases
 Polymorphously Perverse
 Personal negative experience could override social
reinforcement patterns
 Also, peer group can provide more reinforcement
than society at large.
Development of Sexual Orientation

 Importance of labels
 Labels affect perception
 Perception affects behaviour
 Can influence self-perception
 Leading to self-labelling.
Development of Sexual Orientation
 Reiss
 Negative pathway
 Rigidly polarized societies have higher incidence of
male-male sex
 High maternal involvement; Low paternal
 Little opportunity to learn
 Positive pathway
 Very permissive societies
 Experimentation OK.
Bem: The Exotic Becomes Erotic
Boys more active and aggressive
Different = exotic
Bem’s Theory – Criticisms
 There is NO abundant evidence of inborn
aggression and activity levels by gender
 Contaminated by culture
 Homosocial activities are mostly a cultural
phenomenon
 Children who don’t fit the gender stereotypes are
told they are odd and wrong
Bem’s Theory – Criticisms
 Many gays are “gender typical” in their
interests, appearance, etc. Bem fell for the
effeminate guy/macho woman stereotype of
gays.
 Many atypical (i.e., boys who played with
dolls, girls who played with trucks) kids do
not go on to become gay.
Bell, Weinberg and Hammersmith
 In depth interviews comparing gays/ lesbians
and straights.
 No support for psychoanalytic, learning or
sociological (labelling) theories.
 They speculate a biological basis but have no
data.
