Video Game Lowers Stress Hormone

An unexpected discovery suggests playing video games can reduce production of the stress-related hormone cortisol.

The serendipitous finding surfaced from the creation of a video game to help train people to change their perception of social threats and boost their self-confidence.

The new findings appear in the October issue of the American Psychological Association’s Journal of Personality and Social Psychology.

“We already knew that it was possible to design games to allow people to practise new forms of social perception, but we were surprised by the impact this had when we took the games out of the lab and into the context of people’s stressful lives,” said McGill psychology professor Mark Baldwin.

Prof. Baldwin and his team – McGill PhD graduates Stéphane Dandeneau and Jodene Baccus and graduate student Maya Sakellaropoulo – have been developing a suite of video games that train players in social situations to focus more on positive feedback rather than being distracted and deterred by perceived social slights or criticisms.

The games are based on the emerging science of social intelligence, which has found that a significant part of daily stress comes from our social perceptions of the world.

In a 2004 study of 56 students, a standard reaction-time test showed that the game, called the Matrix, helped people shift the way they processed social information. The researchers next conducted several studies to see whether the effects of the game would translate into lower stress levels in a high-pressure context.

In one of their recent studies, they recruited 23 employees of a Montreal-based call center to play one of their games, which involves clicking on the one smiling face among many frowning faces on a screen as quickly as possible. Through repetitive playing, the game trains the mind to orient more toward positive aspects of social life, said Prof. Baldwin.

The call-centre employees did this each workday morning for a week. They filled out daily stress and self-esteem questionnaires and had their cortisol levels tested through saliva analysis on the final day of the experiment.

These tests showed an average 17-percent reduction in cortisol production compared to a control group that played a similar game but without the smiling faces. The cortisol levels were tested by Jens Pruessner of the Montreal Neurological Institute’s McConnell Brain Imaging Centre and Douglas Hospital Research Centre, a co-author of the study.

“There are many possible applications for this kind of game,” said Prof. Baldwin, “from helping people cope with the social anxiety of public speaking or meeting new people, to helping athletes concentrate more on their game rather than worrying about performing poorly.”
