"All work and no play makes Jack a dull boy." But now scientists have given us another warning:too much play with smartphones or computers makes you dull too.
"Many focus on the benefits of digital devices(設(shè)備) in education but ignore the costs," said Patricia Greenfield from the University of California, "losing the ability to understand the emotions of other people is one of the costs."Greenfield and her research team did an experiment.They worked with 105 children who spend about 4.5 hours in front of screens on a school day.The students were asked to describe the emotions towards the pictures of people who were happy,sad,angry or scared.Then,half of them attended a five-day nature and science camp.There they had no smartphones,TV,or computers.The other half stayed in school and spent the five days as usual.Five days later,all the children took the test again.
Students who had been to the camp got about 5 percent more answers correct than they had done before the camp.But the other group of students didn't show much improvement.The study is not perfect in some ways,said the researchers.But scientists say that the study is still a warning for us.
"Emotional skills develop in practice and the brain develops through real interaction."said Professor Taylor,a professor at the University of San Francisco.
Researchers talked to 2,000 parents of children aged 2-16 in the UK about what activities their children could do confidently.
The results were surprising:Their children could use a tablet (平板電腦) (59%)and work a mobile phone (57%) more confidently than they could tie their shoe laces(鞋帶) (53%)!So,spend more time away from mobile phones and computers if you want to be an understanding friend,and not a member of what the Daily Mail called "Generation Helpless".
