Research author Valerie Carson, said: 'This research is based on social cognitive theory, which suggests that seeing people engaged in a behaviour is a way of learning that behaviour.
研究作者Valerie Carson说：“这个研究是以社会认知理论为基础的，它表明看到人们在做某种行为是学习这种行为的方式。”
'Since adolescents are exposed to considerable screen time - over 4.5 hours on average each day - they’re constantly seeing images of behaviours they can then potentially adopt.'

'It’s possible that these types of controls aren’t effective in blocking all undesirable websites.'
“很可能这种控制对于阻止所有不受欢迎的网站是无效的。”
The research, recently published in the Journal of Preventative Medicine, suggests that future studies should examine the specific content adolescents are being exposed to in order to help strengthen current screen time guidelines for youth.
最近发表在《美国医学预防杂志》的研究表明，未来的研究应该检查青少年接触电脑的具体内容，帮助青少年加强对当前播放时间的指导。
