CL Fincher, LM DeBruine, CD Watkins, AC Little & BC Jones (2013). Experimental tests of mate preferences predict real-world mate choice. European Human Behaviour and Evolution Association in Amsterdam, Netherlands. March 2013.

Objective

Here we investigated the relationship between mate preferences measured in the laboratory and actual mate choices. These data have relevance for theories of the evolution of human mate choice and are important for the interpretation of previous research using lab-based measures of mate preferences.

Methods

In a sample of heterosexual romantic couples, we assessed menís and womenís preferences for exaggerated sex-typical shape characteristics (i.e., male masculinity and female femininity) in the faces of hypothetical mates in both long-term and short-term relationship contexts. We also assessed the sex-typicality of each partnerís own face shape.

Results

For both men and women, the sex-typicality of their partnerís face was positively correlated with their preference for exaggerated sex-typical face shapes in long-term, but not short-term, relationship contexts. Also, the extent to which women preferred masculine faces more in short-term than long-term contexts was negatively correlated with their partnersí masculinity.

Conclusion

Our findings reveal direct links between experimentally assessed mate preferences and actual mate choices. Additionally, our findings are consistent with theories predicting that contextual effects on womenís mate preferences are contingent on the physical characteristics of their current mate. Together, these findings suggest that actual mate choices are reflected in experimentally measured face preferences and provide evidence to support theories of the function and evolution of human mate choice.
