Living in cities or towns can reduce people's ability to concentrate on tasks, research suggests.
People who live in remote areas can pay attention to the task in hand better than those living in towns or cities, researchers said.
Researchers, from Goldsmiths University of London, examined a remote Namibian tribe and found that those who had not moved to an urban environment were better able to concentrate in cognitive tests.
Lead author Dr Karina Linnell, from the University's Department of Psychology, said people living in an urbanised environment were not functioning at their optimum level of engagement.
"What if, for example, companies realised certain tasks would be better carried out by employees based outside of the urban environment where their concentration ability is better," Dr Linell asked.
