Previously depressed patients continue to focus on negative

Healthy participants as a group responded more quickly to emotional and non-emotional stimuli than participants with a history of depression, regardless of whether those stimuli were positive, neutral or negative. But participants who previously had major depressive disorder spent more time processing negative emotional stimuli over positive stimuli compared with controls. While healthy controls showed a significant difference in how much time they spent processing positive vs. negative emotional stimuli compared with those in remission from major depression, that distinction did not appear when comparing time spent processing negative vs. neutral or positive vs. neutral stimuli.

Overall, the findings suggest that individuals with recurrent major depressive disorder not only are less able to control the information they process than healthy individuals, they also display a greater bias for focusing on negative over positive or neutral information, according to researchers.
