The results of this work showed that depressed people took longer on average than the other groups to correctly identify happy facial features, and shorter on average to identify sad facial features than the other groups. Similarly, the anxious group took less time on average to identify the angry faces than the other two groups. Since time in this case corresponds directly to degree of intensity of facial expression, taking longer is the same thing as requiring a stronger, more obvious display of emotion, while taking less time means that more subtle facial emotional displays are being detected.
