Jealousy can be so powerful that it can leave a person "functionally blinded," unable to see key images in their immediate environment. That's the core finding of a study by two psychologists at the University of Delaware, who have been running for cover ever since their study was published in the journal Emotion a few days ago. Dr. Skripka answers the question: 'How Do I Keep Siblings From Jealousy?' Steven Most, a cognitive psychologist, and Jean-Philippe Laurenceau, a specialist in social relationships, conducted two experiments involving a total of 52 romantically involved couples on the Newark campus. They wanted to see if jealousy can be strong enough to cause "emotion-induced blindness." Their research shows that women who admitted they were jealous when their guy ogled photos of other women (presumably female students at the university who were "accessible") couldn't concentrate on a basic computer task well enough to recognize simple images that flashed quickly across the monitor. The problem, judging by many reports on the research, is the work showed that women could be blinded by jealousy, but not necessarily men.
