It also indicates that he can survive despite his disadvantages.

Campbell, A. (2002). A Mind of Her Own: The Evolutionary Psychology of Women. New York: Oxford. The Red Queen Effect By reproducing sexually, animals produce offspring that vary in their resistance to different strains of parasite –Females select males for disease resistance and with the fewest parasites

Campbell, A. (2002). A Mind of Her Own: The Evolutionary Psychology of Women. New York: Oxford. How Do Females Read Healthiness? 1) Quality of ornaments or helpful traits 2) Secondary sexual characteristics –Sexually selected traits are more affected by poor health than other neutral traits. –Women don’t care about ankle size. Women won’t automatically get rid of a mate if that is altered by parasites, but they will if sexual traits are infected. 3) Symmetry 4) Physical evidence of quality: Maturity, Dominance, Gifts

Long-term vs. Short-term Relationships Long Term: 1) Women are more choosy 2) Prefer to wait longer before having sex with a man 3) Value resources and good parenting qualities in men Short Term: 1) Women enter short-term relationships when there are too few men 2) Her upbringing has signaled that men are unreliable investors in her offspring 3) Women want attractive men with lots of symmetry …basically they just want the best genes!

Campbell, A. (2002). A Mind of Her Own: The Evolutionary Psychology of Women. New York: Oxford. Dawkins (1989): Frequency-Dependent Selection As unrestricted females become more common, the male’s optimal strategy changes from monogamy to providing nothing more than genes As the number of restricted females increases, non- committed males will find it increasingly hard to find partners and their pay-off will be ZERO! “ Cads offer their genes as the prize while dads offer long-term resources” Ex. Mimicry in moths

Women’s Access to Resources Eagly & Wood (1999) –As women become more empowered they place less importance on the value of a prospective partners earnings Draper & Harpending (1982) –The absence of a consistent male figure in the home signals to the girl that paternal investment is rare and that she is unlikely to secure a mate (i.e., girls with no dads go for the cads)

Aggression Aggression tends to be heritable, but the expression of it depends on the environment. –Many aggressive girls come from dysfunctional homes where they learned to solve problems by fighting. Female-Female attacks are characterized by: –Women ages years old –Between friends and acquaintances –Using hand-to-hand contact (pushing, shoving, grabbing, slapping, punching)

Campbell, A. (2002). A Mind of Her Own: The Evolutionary Psychology of Women. New York: Oxford. Three Motives Likely to Spark Violence 1) Sexual Reputation –For a man to commit long-term he needs to be reassured of the woman’s fidelity, so he is not aimlessly wasting his resources. –Girls judge sexual reputation harsher than males and will avoid being friends with someone considered “loose” for fear of reputation by association. “ A girl being called a slag is the same as a boy that’s been called a chicken…” –A man can prove he is not a chicken, but a woman cannot prove she is not “loose” –This forces her to use violence to minimize the threat of a negative reputation. “The most desirable women can pick & choose--they don’t need to resort to the ‘cheap trick’ of sex. A woman who is discriminating in her choice of partners signals that she believes she is worth waiting for.”

Campbell, A. (2002). A Mind of Her Own: The Evolutionary Psychology of Women. New York: Oxford. Three Motives Likely to Spark Violence 2) Competition –Female dependence on men for resources drives competition among women. The more the women need the men, the more injury that is inflicted. –This competition comes from the lack of good, resourceful men and a woman’s need to access these resources.

Campbell, A. (2002). A Mind of Her Own: The Evolutionary Psychology of Women. New York: Oxford. Three Motives Likely to Spark Violence 3) Jealousy –Once a woman attracts a male, she must keep him away from other women. –Mutual dependence of economic support by one man causes a fight for resources. –“Spillover Effect”: Girls believe they have a right to a man if they are simply attracted to him and they will continue to fight for him once the relationship has ended.

Campbell, A. (2002). A Mind of Her Own: The Evolutionary Psychology of Women. New York: Oxford. Aren’t the Men Just As Guilty?

(The Double Standard) –A woman knows where a man is weak. She knows how to protect her interests if someone tries to mess with her man –Girls go after each other because they know women should know better than to mess with someone else’s mate

Campbell, A. (2002). A Mind of Her Own: The Evolutionary Psychology of Women. New York: Oxford. Critical Review Strengths/ Agreements No matter how many resources women have they still seek males with good resources. Women base their sexual preferences on cues from the environment. A man’s desirability in the past increases his future reproductive success, while a woman’s makes her seem desperate.
