[ti:Study: Number of Kids Watching Online Videos Doubled in 4 Years] [by:www.51voa.com] [00:00.00]更多听力请访问51VOA.COM [00:00.04]A new study has found that the number of young Americans who watch [00:05.06]online videos each day has more than doubled in the past four years. [00:12.84]The findings were based on a survey of about 1,700 young people aged 8 to 18. [00:23.48]Results were released this week by the U.S.-based [00:27.54]not-for-profit group Common Sense Media. [00:32.80]The group researches youth technology activity and offers guidance for parents. [00:40.72]Fifty-six percent of 8- to 12-year-olds taking part in the survey [00:46.40]said they watched online videos each day. [00:51.20]That rate jumped to 69 percent for 13- to 18-year-olds. [00:58.48]A 2015 survey by Common Sense Media found the rate was 24 percent [01:05.15]for 8- to 12-year-olds and 34 percent for 13- to 18-year-olds. [01:13.12]The survey found that overall screen time for young Americans [01:17.80]did not change much over the past four years. [01:22.80]On average, preteens spent just under five hours of screen time on devices each day. [01:32.08]Teens had about seven and a half hours of screen time. [01:37.40]The numbers did not include time young people spent on their devices [01:42.44]doing homework, reading books or listening to music. [01:48.72]Common Sense Media's director of research, Michael Robb, told The Associated Press [01:55.64]that such screen time among American youth "really is the air they breathe." [02:03.76]The findings suggest a continuing change by young people [02:08.41]to move away from traditional television [02:11.52]to watch streaming video services on their phones and other personal devices. [02:18.84]Only about one-third of teens surveyed [02:22.28]said they enjoyed watching traditional television programming "a lot." [02:28.44]This compared with nearly half of those surveyed four years ago. [02:34.60]About half of preteens said they enjoyed watching traditional television "a lot," [02:40.86]compared with 61 percent in 2015. [02:44.96]YouTube, which is owned by Google, was the number one choice of youth [02:51.28]for online videos, even among the preteens surveyed. [02:57.14]Three-quarters of the preteens said they use the site even though it has age restrictions. [03:05.64]Only 23 percent of preteens said they watch YouTube Kids, [03:10.48]a separate service aimed at their age group and even younger children. [03:16.88]Of those who said they used YouTube Kids, [03:20.30]most said they enjoyed the regular YouTube site better. [03:25.60]Robb said the common use of YouTube by young people [03:29.83]"puts a lot of pressure" on parents to find ways to restrict what their children see. [03:37.56]In answer to the survey, YouTube said the company [03:41.56]is rethinking the way it deals with children and families. [03:47.48]A spokesman for YouTube, Farshad Shadloo, [03:51.32]repeated the company's terms of use on age: [03:55.52]"YouTube is not a site for people under 13," he said. [04:02.12]The company said YouTube Kids and its restriction tools [04:07.04]are designed to limit site usage for preteens. [04:12.08]But experts say it is easy for many children to get to the videos they want to watch, [04:18.24]whether on YouTube or another streaming service. [04:23.52]Sarah Domoff is a professor at Central Michigan University [04:28.17]who studies the effects of technology on youth and families. [04:33.45]She told the AP that parents often do not have the time [04:38.41]or skills to limit what their children are watching effectively. [04:44.08]Domoff said she thinks many parents could do more [04:47.78]to try to track the screen time of their children. [04:51.92]She added, however, that tools aimed at limiting usage on services [04:57.17]such as YouTube could be greatly improved. [05:01.08]"It's really hard to block out certain things [05:04.40]unless you're really standing over your child," Domoff said. [05:09.59]I'm Bryan Lynn. 更多听力请访问51VOA.COM
