Time/resources/energy devoted to raising child.

 Difference between sexes.

Difference in investment linked to other behaviour differences.

-More competitive with members of own sex.

-Mature later

-Live less

-Less fussy about choice of mate

-More aggressive

Sexual prefences part of sexual strategy- to maximise chances of passing on genes.

Sexual preferences shaped by evolution and parental investment

Typical of Homo Sapiens.

Dedication of resources over a long preiod, to relationship and child bearing.

MEN preferences- related to fertility and reproductive value.

WOMEN preferences- related to ability to provide for mother and child.

Women less likely to engage (Clark & Hatfield)- cultural pressure/ fear of violence.

Men: Quantity over quality

Women: Quality over quantity

*Can benefit from short-term mating if exceptionally good male.

Short/Long-term depends on comparisons, sex ratio, opportunity.

Short term:

·Men want more sexual variety

·Men keener to consent to sex

·Men will actively seek more partners

Found 'sexual strategy theory' evidence across cultures and countries-

HOWEVER:

·self-reports (men bragging?)

·mainly students- student subculture?

Alternative to Schmitt's sexual strategies.

Focus on social factors, not as much evolution.

The 'Environment of Evolutionary Adaptiveness'- usually pleistocene era

*HOWEVER- circulatory? posit the evolutionary past that fits the most with our evolutionary esplanation of the present.
