A new study has revealed that people improve their performance more when they practice with a partner rather than on their own.
Scientists from Imperial College London and two Japanese institutions explored whether physical interaction improved the way people performed in a computer-based task where they were using a joystick-like device.
They were connected by a virtual elastic band to the same type of device operated by another person, who was hidden from view.
Most of the participants were unaware that they were working with a partner, but in spite of this they subconsciously used information transmitted through their partner's touch to enhance their performance.
It was found that participants achieved noticeably better results in the task when working with a partner than they did working on their own.
The researchers are particularly interested in how their findings could help people performing exercises for rehabilitation, for example when recovering from stroke.
"Our study is helping us to understand how touch plays a vital and very subtle role in helping people to transmit information to one another. This was the case in our study even when people couldn't see their partner or feel their partner's skin," Dr Etienne Burdet, co-author of the study from the Department of Bioengineering at Imperial College London, said.
In the study, the researchers discovered that where one person was physically connected to a partner when learning a task, they consistently improved their performance regardless of how well their partner performed.
Even an intermittent physical connection between partners was found by the researchers to help individuals to learn the task better than subjects who practiced the task alone for the same duration.
The study was published in the journal Scientific Reports.
