Men's long-term mating preferences
| Term | Definition |
|---|---|
| Since female reproduction (pregnancy, labor, delivery) harder | it is more variable, giving men more cues |
| plumpness preferred if | food in short supply |
| thinness preferred if | food is plentiful |
| extremes are | unatractive |
| Larger breasts get | more tips from both men and women in bars |
| most mammals have enlarged breasts only | when feeding babies |
| because breasts get larger with age | large breasts should be unattractive |
| non-human female with large breasts cannot reproduce | so they are avoided by males |
| humans only have large breasts all the time | not useful for breast feeding capacity |
| hypotheses for male large breast preference | butt-imitation, oxytocin bonding, female resource status signal, covert ovulation |
| butt-imitation hypothesis | humans mate face to face, but take advantage of butt preference EPM |
| oxytocin bonding hypothesis | lactating hormone increases female bond, but female already mostly L-T maters. Why not enlarged male breasts? |
| female resource status signal hypothesis | large breasts show fat enough, but why not fat elsewhere, pub raters liked big breasts more before eating |
| short-term mating men prefer | large breasts more |
| covert ovulation hypothesis | deception undermined by change in breast size, get constant male attention, can't tell when breast feeding (first 3 months) |
| WHR | during puberty fat shifts to hips |
| juvenile female WHR | .85-.95 |
| adult female WHR | .69-.85 |
| pear shape signals | lower HWR, not pregnant |
| apple shage signals | higher HWR, conception difficulties, disorders (diabetes, cardiovascular disease) |
| lower female HWR is correlated with | higher female interest in sex |
| line drawings best HWR .70 | regardless of plumpness |
| .70 HWR favoured for | escorts, Playboy models, UK, India but not Peru, Tanzania (.8 prefered): maybe .7 seen as abnormal |
| long legs as a % of height more attractive | biomechanical advantage, China study-more offspring |
| women wear high heels to | make legs look longer |
| Not cultural preference for attractiveness | babies prefer attractive females, dolls, 1yr. olds interact more |
| high correlation of female attractiveness | accross cultures |
| blind men prefer | WHR .7 manequins |
| beauty preference not | primarily learned |
| Men value physical variables for long-term mates because | not crowded out by resource desires |
| women always choose attractiveness as | less valuable then men do |
| only men invest in | offspring |
| covert ovulation heightens | paternity uncertainty |
| paternity uncertainty drive of | long-term mating (eg. marriage) |
| marriage gives men | regular and exclusive sexual access: paternal certainty |
| love gives men | commitment and sexual fidelity |
| love gives women | long-term shared resources |
| chastity signals | sexual restraint |
