Other studies have found that sad moods tend to sharpen our attention: They make us more focused and detail oriented; they improve our memories, correct our cognitive biases. For example, University of New South Wales psychology professor Joseph Forgas found that people are better able to recall items they’ve seen in a store on cloudy days compared to sunny ones, and that people in a bad mood (after being asked to focus on sad memories) tend to have better eyewitness memories of a car accident than those who’d been thinking of happy times.
