This new study certainly puts men through the wringer. The research said a woman reveals all in her eyes but it's hard to read if you're a man.

Researchers from Germany and Austria were curious to figure out how emotions could be recognized just by looking at the eyes, specifically why it was problematic for men to figure the mental states in women.

The dramatic findings appear in the PLOS ONE journal and showed that the men had a harder time figuring out emotions of woman compared to other men's emotions, but there was something going on, specifically the lack of function, in the limbic region of the brain that explained why.

The limbic system is responsible for garnering attention to emotional events, memories and pleasure, among others, so when researchers put 22 men between the ages 21 and 52 inside a functional magnetic resonance imaging scanner, they were able to intercept the brain activities while the men took a "Reading the Mind in the Eyes Test," or RMET.

The RMET asked them to look at pictures of 36 pairs of eyes and guess the person's emotion that they feel correlates with it. The test scores were low when they guessed women's feelings.

"We showed for the first time that better performance in recognizing emotions from male [versus] female eyes was linked to differential activation patterns in areas that have been previously linked to mentalizing performance," researchers said in the study.

The eye has been heavily researched to uncover how it tells all about a person's daily habits. One evolutionary study has shown that men could quickly detect angry faces of other men compared to women, suggesting that the male is more familiar to angry faces. Another study that used an eye tracking technology found men spent 65 percent more time viewing online photos on dating sites while women use 50 percent more time reading into a man's profile, life and interests.

Overall, this current research reveals that not only is it hard to read, but men are not built to read women's emotions--but they can be trained.

Researchers liken the training exercises to hunting and fighting.

"As men were more involved in hunting and territory fights, it would have been important for them to be able to predict and foresee the intentions and actions of their male rivals," researchers said.
