 Young, J.A., Critelli, J.W., & Keith, K.W. (2005). Male age preferences for short-term and long-term mating. Sexualities, Evolution and Gender, 7,

 148 males from a large southwestern university in the USA  Male age preferences for short-term and long-term mating  Age range from 17 to 29 years old  The mean age was  All had to be 30 yrs or younger, not married, without children, and heterosexual

 Created a “cultural scenario” separate from the norms of American culture and society  Created the new “world” with elements of sexual fantasy so that a context for “making age preference choices” would manifest itself  Allows for closer approximation to the effects of evolutionary predispositions

 Participants read hypothetical scenario placing them in “Arunta” culture  Were told females at age 13 were considered adults  Told it was not uncommon to have one-night sexual encounters, but that marriage was “for life”  both occur in equal amounts

 Asked about:  If it would be easy to act as an adult the “Arunta” Culture?  What age would your bride be if having an arranged marriage?  What age would you “live independently” of parents?  If someone was arranging a one-night sexual encounter what age of female would you prefer?  Also asked to describe reasoning behind answers ( 1 and 3 buffer questions)

 “Males preferred younger females for long term sexual relationships than for a brief sexual encounter”

 One-Night Sexual Encounter  males prefer females to be (mean) years of age  2.07 years younger than males  Marriage  males prefer females to be (mean) years of age  3.02 years younger than males

 Max future reproductive value is younger than age of optimal fertility  When looking for short term relationship males look for older females  When looking for long term relationship males want a younger aged female  Provides support for “partial genetic control” for age preferences in short and long term partners

 Should ask older males  May have overemphasized young rather than older females in study  Stating that adult is 13 (priming?)  Only used university students  Should do some cross-cultural analysis
