男女选择伴侣的标准各不同

A new study suggests individuals choose a partner based upon their perception of a potential mate's attributes and upside or downside potential.

新研究表明，个人在选择伴侣时往往基于潜在另一半的个人特征及其上升潜力或下行空间。

Researchers determined men and women often use a framing process evaluating suitors from both positive and negative perspectives.

Still, as described in the journal Evolution and Human Behavior, decision-making varies as each gender uses different criteria and viewpoints to make their choice.

For example, researchers from Concordia University discovered men responded more strongly to the "framing effect" when physical attractiveness was described.

Also, it may come as a surprise to learn that when we choose a partner, the framing effect is even stronger in women than it is for men.

"When it comes to mate selection, women are more attuned to negatively framed information due to an evolutionary phenomenon called 'parental investment theory,'" said Gad Saad, Ph.D.

"Choosing someone who might be a poor provider or an unloving father would have serious consequences for a woman and for her offspring. So we hypothesized that women would naturally be more leery of negatively framed information when evaluating a prospective mate."
