Evolution and Human Behavior: Gender differences & romance

When it comes to romantic partners:

men seem to focus on physical beauty

women seem to focus on status

 

 


Kenrick, Gutierres, and Goldberg, 1989

What they did:

Show heterosexual men and women either opposite sex nudes or abstract art.

Then have everyone rate their satisfaction with their current romantic partner.

What they found:

Women were unaffected by the manipulation.

Men were more dissatisfied with their current partner after looking at nudes.

Conclusion:

Men are more affected by physical beauty than are females

 

 

 


Kenrick, 1992

What he did:

Set up a "dating game." Manipulated physical attractiveness and status of prospective dates.

What he found:

Men were attuned to physical attractiveness, but not status. Women were attuned to status, but not physical attractiveness.

 

 

 

 

 

 


Buss & Schmitt

 

 

 


So how do we turn this difference into an evolutionary account?

 

 

 


An Evolutionary account of men's focus on physical beauty

 

 

 

 


An Evolutionary account of women's focus on status

 

 

 

 

 


A Slightly Different Gender Difference

What Buss did:

Asked men and women to imagine that their romantic partner was engaged in either a physical or emotional relationship with someone else.

Then asked them to indicate how "upset" they would be.

What he found:

Women were more upset imagining emotional relationship.

Men were more upset imagining physical relationship.

 

 

 

 

 


But what is beauty?

Is beauty defined by evolution or by culture?
