When we think about depression - sadness, apathy and preoccupation are the things that comes to our mind first but a new study has overturned it and suggests that depression too has a positive side-effect.
Bettina von Helversen (University of Basel, Switzerland), Andreas Wilke (Clarkson University), Tim Johnson (Stanford University), Gabriele Schmid (Technische Universitat Munchen, Germany), and Burghard Klapp (Charit Hospital Berlin, Germany) found that depressed individuals perform better than their non-depressed peers in sequential decision tasks.
In their study, participants - who were healthy, clinically depressed, or recovering from depression-played a computer game in which they could earn money by hiring an applicant in a simulated job search.
The result showed that depressed patients approximated this optimal strategy more closely than non-depressed participants did.
While healthy participants searched through relatively few candidates before selecting an applicant, depressed participants searched more thoroughly and made choices that resulted in higher payoffs.
The study is detailed in the forthcoming Journal of Abnormal Psychology.
