In The Joy of Stress, Dr. Peter Hanson described an experiment in which two groups of office workers were exposed to a series of loud and distracting background noises. One group had desks equipped with a button that could be pushed at any time to shut out the annoying sounds. The other group had no such button. Not surprisingly, workers with the button were far more productive than those without. But what’s remarkable is that no one in the button group actually pushed the button. Apparently, the knowledge that they could shut out the noise if they wanted to was enough to enable them to work productively in spite of the distractions. Their sense of _____ resulted in a reduction in stress and an increase in productivity. ① humor ② achievement ③ control ④ responsibility
