Be careful, jealousy can interfere with vision, especially in women. At least that's the result of research psychologists, who say that jealousy can affect women's ability to see things clearly. It has long been known that the emotions involved in social relationships can affect one's physical and mental health. But now it seems the social emotions literally can also affect the ability of vision.

Through a trial, found that women who are jealous of the fire burned so emotionally disturbed that they are difficult to focus the view. This research has been published in the American Psychological Association, April edition. In that study, Prof.. Most Steven and Jean-Philippe Laurenceau from the University of Delaware and his colleagues tested romance heterosexual couples.

The couples were asked to sit near each other on separate computers. Female participants were then asked to detect targets in the form of views in the midst of a fast rotation of images, while trying to ignore the occasional emotional when confronted with other images, such as graphics or images that scary. While male participants were asked to rate the attractiveness of landscape images that appear on the screen.

In the next stage of the research team instructed participants to rate male attractiveness of the women are single. From here then, the researchers assessed the participants and asking women about their feelings of discomfort when their partners were asked to rate the level of attractiveness of other women.

The results, which feels increasingly jealous of the women, the more they felt disturbed by the appearance of other images so that they can not see the target clearly. The relationship between jealousy and "emotion caused blindness" occurs only when the male partner rate of other women. But researchers do not know what would happen if the rules are reversed and the jealousy of the men tested.
