Positive effects of depression

05.05.2011
Evidence that depression has a positive side-effect

Sadness, apathy, preoccupation. These traits come to mind when people think about depression, the world's most frequently diagnosed mental disorder. Yet, forthcoming research in the Journal of Abnormal Psychology provides evidence that depression has a positive side-effect.

According to a new study by Bettina von Helversen (University of Basel, Switzerland), Andreas Wilke (Clarkson University), Tim Johnson (Stanford University), Gabriele Schmid (Technische Universität München, Germany), and Burghard Klapp (Charité Hospital Berlin, Germany), 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 game assigned each applicant a monetary value and presented applicants one-at-a-time in random order. Experiment participants faced the challenge of determining when to halt search and select the current applicant.

In addition to resembling everyday decision problems, such as house shopping and dating, the task has a known optimal strategy. As reported, 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.

This discovery provides the first evidence that clinical depression may carry some benefits. For decades, psychologists have debated whether depression has positive side-effects.

While researchers have recognized that most symptoms of depression impede cognitive functioning, scholars such as Paul Andrews of the Virginia Institute for Psychiatric and Behavioral Genetics and Andy Thomson of the University of Virginia have proposed that depression may promote analytical reasoning and persistence -- that is, qualities useful in complex tasks.

Past research provides some evidence in support of this possibility, but it focuses on individuals with low levels of non-clinical depression.

The forthcoming article shows that even severe depression might yield some beneficial side effects. Fully understanding the consequences of depression may help uncover its evolutionary roots and thus opening avenues for treatment.

Im Focus: Manipulating Electron Spins Without Loss of Information

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.

For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...

Im Focus: The proton precisely weighted

What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.

To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
