First you hear from Anna Campbell, a Professor of Psychology at Durham University. Her research interests concern gender differences in aggression and evolutionary psychology. - from wikipedia

Then hear from girls going out to party regarding what they want from a one night stand and a relationship.

For a one night stand (ONS), one girl wants a good looking guy, another wants a bad boy, and another wants someone good in bed

For a relationship, one girl says she'll have to search little deeper (answered bad boy to the ONS question), a group of girls say that personality starts to matter, and another girl says the guy has to be very considerate.

Anna Campbell - "they choose the male that they think is the best they can find"

Anna Campbell - "women in a sense are the choosers, they retain as it were, that power"

Anna Campbell is the author of this famous study on gender differences in perception of one night stands: http://link.springer.com/article/10.1007%2Fs12110-008-9036-2

Another quote from her: "Basic emotions guide us down pathways that have been advantageous for our ancestors"

I just couldn't resist throwing this one in as well from David M. Buss, a professor of psychology at the University of Texas at Austin, known for his evolutionary psychology research on human sex differences in mate selection. - wikipedia

"The best predictor of sexual infidelity is number of sex partners prior to marriage" http://vimeo.com/19921928#t=26m08s
