Think you can walk, rive, take phone calls, email and listen to music at the same time? Well, New York’s new law says you can’t. and you I’ll be 41 $100 if you do it on a New York City street.
The law went into force last year, following recent research and a (n) 42 number of accidents that involved people using electronic devices when crossing the street.
Who’s to 43 ? scientists say that our multitasking（处理多重任务的）abilities are limited.
“We are under the impression that our brain can do more than it often can ,” says Rene Marois, a scientist in Tennessee. “But a major limitation is the inability to 44 on two things at once.”
The young are often considered the great multitaskers. However, an Oxford University research suggests this idea is open to question. A group of 18-to 21-year-olds and a group of 35-to 39-year-olds were given 90 seconds to translate 45 into numbers, using a simple code. The younger group did 10 percent better when not interrupted. But when both groups were interrupted by a phone cal or a (n) 46 message, the older group matched the younger group in speed and 47 .
It is difficult to measure the productivity lost by multitaskers. But it is probably a lot. It is estimated that the cost o interruptions to the American economy is nearly $650 lillion a year.
The 48 is based on surveys with office workers. The surveys conclude that 28 percent of the workers’ time was spent on interruptions and 49 time before they returned to their main tasks.
