RESEARCH WITH MEMBERS OF THE LGBTTIQQ COMMUNITY IS SAMPLE
BIAS!!!!!!!!! PEOPLE WHO TAKE PART ARE THOSE WHO CHOOSE TO
PARTICIPATE.
Intimate relationships
Happiest group was married mixed-sex couples THEN cohabiting same sex couples
single people were the least happy
Lesbian couples report greater relationship satisfaction
Desire for and achievement
Affectional orientation development
Components: sexual attraction etc.
Etiology issue – researchers rely on a persons sexual identity label to separate
participants into groups
Assumption that heterosexual is the default orientation
Biological explanation for determining affectional orientation
Restricted to male-male sexuality
oSame sex sexual behaviour is more common in males than females
oMore research regarding male male sexual behaviour
oReligious and moral concerns are more focused on male male sexuality
BIRTH ORDER AND FERTILITY OF RELATIVES CAN AFFECT THIS
Gay men have a smaller part of hypothalamus (2 or 3 times smaller)
Gay men have larger corpus callosum
Brain is activated differently faster or slower in some gay men than in straight
men
MOST CONSISTENT
oHand preference and fraternal birth order – gay men are more frequently
left handed, 34% greater chance of being left handed
oGreater number of older brothers a male has, the more likely he will
identify as gay ONLY IF THEY ARE RIGHT HANDED
oGay males WITHOUT older brothers is more likely to be LEFT
HANDED
JOHN MONEY
