NO ME DIGAS:

While men tend to match their partners' emotions during mutual cooperation, women may have the opposite response, according to new research.

[...] She and her colleagues found that during high mutual levels of cooperation with a romantic partner, men typically experience an "inphase" response to their significant other's emotions. That is, if the woman in the relationship is feeling more positive, the man will feel more positive. If she feels less positive, he will feel less positive.

On the contrary, it seems women experience more of an "antiphase" pattern during high mutual cooperation. If her partner is feeling more positive, she will tend to feel less positive, and vice versa.

Eso se lo hubiera dicho yo sin necesidad de que investigaran demasiado...
