　　Edward Cornish, the editor of the Futurist magazine, published by the World Future Society, says:

　　3. Your 21st century brain
　　Your brainwaves maybe used to check out whether you're busy, tired or doing your work properly.
　　Psychologist Arthur F.Kramer, at the university of Illinois, tested volunteers working on arithmetic problems.
　　He found that he could predict their performance from the strength of the brain's electrical activity.
　　This is measured through the scalp.
　　The future? Bosses could measure brain activity through the scalp and tell whether a worker is performing well, working hard, or too tired to do the job properly.
