University Of Chicago : 22 July, 2007  (Technical Article)
New research at the University and the University of California, Santa Barbara, shows that women subconsciously pick up cues in men
The research also shows that womenís judgments of menís facial masculinity accurately reflect menís testosterone levels. Accordingly, women are attracted to those men for short-term relationships.

ďThe study provides the first direct evidence that womenís attractiveness judgments specifically track both menís affinity for children and menís hormone concentrations,Ē said Dario Maestripieri, Associate Professor in Comparative Human Development, and co-author of ďReading Menís Faces: Womenís Mate Attractiveness Judgments Track Menís Testosterone and Interest in InfantsĒ published in the Tuesday, May 9 issue of the British scientific journal The Proceedings of the Royal Society B: Biological Sciences.

Women are fairly accurate in being able to determine interest in children and testosterone levels, said James Roney, assistant professor at the University of California, Santa Barbara, the lead author of the paper. ďOur data suggest that menís interest in children predicts their long-term mate attractiveness, even after we account for how physically attractive the women rated the men,Ē he said.

Joining the two in the study are Katherine Hanson, a graduate student in anthropology at the University of California, Santa Barbara, and Kristina Durante, a graduate student in psychology at the University of Texas, Austin.

For the study, researchers in Maestripieriís laboratory recruited male undergraduate students from a variety of ethnic backgrounds who were tested for testosterone and for their interest in children. Researchers took saliva samples to measure testosterone levels.

To determine interest in children, researchers showed the 39 men in the sample pairs of pictures, one of an adult and the other of a baby. They were asked which picture they preferred. Five of the men expressed no interest in the baby pictures, while the rest expressed a range of interest, up to preferring the baby pictures exclusively.

The researchers then took pictures of each man, asking them to display a neutral expression. An oval frame was placed around each photo to focus attention to the faces and the photos were shown to 29 undergraduate women from diverse backgrounds at the University of California, Santa Barbara.

The women were asked to rate the men according to whether they thought the men liked children, whether they appeared masculine, physically attractive or kind. They were then asked to determine menís attractiveness as short-term romantic partners or as long-term partners for relationships, such as marriage.

The men women chose as being most interested in children were also the same men who had expressed the most interest in children in the photo test. The women also were able to determine from the photos which men rated high on testosterone levels because they perceived the men as looking masculine.

Although women said they were attracted to the men who tested high for testosterone, an important factor in their attraction to men for a long-term relationship was their perception of a manís affinity for children, even after accounting for their perceptions of menís general kindness.

ďThe research suggests that menís interest in children may be a relatively underappreciated influence on menís long-term mate attractiveness.Ē Roney said.
