Performance Can Improve When We Know We Have an Audience

While people think performing in front of others will make them mess up, a new study has found that being watched actually makes people do better.

When people know they are being observed, parts of the brain associated with social awareness and reward stimulate a part of the brain that controls motor skills, improving their performance at skilled tasks, according to the study led by a Johns Hopkins University neuroscientist.

“You might think having people watch you isn’t going to help, but it might actually make you perform better,” said lead author Dr. Vikram Chib, an assistant professor of biomedical engineering at Johns Hopkins and the Kennedy Krieger Institute. “An audience can serve as an extra bit of incentive.”

Chib, who has studied what happens in the brain when people choke under pressure, originally launched this project to investigate how performance suffers under social observation.

But it quickly became clear that in certain situations, having an audience spurred people to do better, the same way it would if money was on the line, he said.

Previous studies have shown that when people are observed, brain activity jumps in areas of the brain known for thinking about others, even if people aren’t doing anything that others could judge.

But researchers had not tested to what degree, if any, people in front of an audience might work harder in pursuit of a reward, or what happens in the brain during this type of social situation, Chib noted.

For this study, Chib and his colleagues devised an experiment, held at the California Institute of Technology, in which 20 participants performed a task and were paid a small amount of money contingent on how well they did.

The task was a video game similar to Wii or Xbox Kinect. The participants performed the task both in front of an audience of two and with no one watching. Their brain activity was monitored with functional magnetic resonance imaging, the researchers reported.

When participants knew an audience was watching, a part of the prefrontal cortex associated with social cognition, particularly the thoughts and intentions of others, activated along with another part of the cortex associated with reward, according to the study’s findings.

Together these signals triggered activity in the ventral striatum, an area of the brain that motivates action and motor skills, the researchers explained.

The presence of an audience, at least a small one, increased people’s incentive to perform well, Chib said, noting the brain scans validated this by showing the neural mechanism for how it happens.

When people were watching, participants were an average of 5 percent better at the video game — and as much as 20 percent better. Only two participants didn’t perform better in front of others.

But if the audience was a lot bigger, and the stakes higher, the results could have gone the other way, the researchers note.

“Here, people with social anxiety tended to perform better, but at some point, the size of the audience could increase the size of one’s anxiety,” Chib said. “We still need to figure that out.”

The study was published in the journal Social Cognitive and Affective Neuroscience.
