Depression, characterized by a significant and persistent low mood, is the main feature. The World Health Organization predicts that depression will become a major human killer in the 21st century. The recurrence rate of depression is extremely high, with statistics showing that 8 out of 10 people with a history of depression will relapse again. Scientists say that a simple test can tell you how likely you are to develop and relapse depression. The test was derived from a study by the State University of New York at Binghamton. They surveyed 160 women, 60 of whom had a history of depression and 100 of whom did not. In the study, they showed each subject two photos of the same person, one with a neutral expression and the other with an expression of anger, sadness or happiness. Using eye tracking, it was found that people whose eyes were more likely to be drawn to angry faces were at greater risk of developing depression than those who focused on neutral or happy expressions in the first place. In addition, those women with a history of depression also paid more attention to angry faces. What’s more, the study’s findings then point out that women with a history of depression are likely to suffer from depression again within the next two years if they are first attracted to angry faces.
