Inter-sexual selection: females
intra-sexual selection: males
Explain inter-sexual selection
Quality over quantity
Trivers said that females put more effort into finding a mate, as females have to bare the child
-Sexy son hypothesis, Fischer (enhanced through reproduction)
-Runaway process (characteristic becomes exaggerated)
What is the sexy son hypothesis
Inter-sexual selection
Essentially that women make with people to have sons that look alike
Explain intra-sexual selection
Quantity over quality

Factors affecting attraction: Self-disclosure- EVAL
-Specher and Hendrick, 2004, studied heterosexual relationships between partners and found there were correlations between satisfaction and level of self-disclosure.
More self disclosure had better relationships
Sprecher et al ,2013, found reciprocal self-disclosure best when taken in turns
-Self-disclosure is not direct to satisfaction. Satisfaction may not come from disclosure perhaps a 3rd variable
-Self-disclosure improves communication in relationships. Self disclosure increases intimacy. Hass and Stafford found 57% homosexual men + women use self-disclosure as a way of deeper affection and communication
-Not all cultures require self-disclosure to improve communication. Tang et al 2013, reviewed sexual disclosure in men and women in US and China. US had much more self-disclosure, but no differences in satisfaction across countries. Ethnocentricism - cannot generalise
