NEWARK, DEL. – Jealousy really is "blinding," according to a new study by two University of Delaware psychology professors. They found that women who were made to feel jealous were so distracted by unpleasant emotional images they became unable to spot targets they were trying to find.
The researchers suggest that their results reveal something profound about social relationships and perception: It has long been known that the emotions involved in social relationships affect mental and physical health, but now it appears that social emotions can literally affect what we see.
