Excessive internet use may cause parts of teenagers’ brains to waste away, a study reveals. Scientists discovered signs of atrophy of grey matter in the brains of heavy internet users that grew worse over time. This could affect their concentration and memory, as well as their ability to make decisions and set goals. It could also reduce their inhibitions and lead to ‘inappropriate’ behaviour. 在这个网络泛滥的年代，各式各样的智能手机、社交网络让爆炸化的信息充斥着我们的生活，我们的生活因网络变得紧密，与此同时，我们的生活也因网络而愈渐疏远。有消息称，青少年过度使用英特网会损害部分大脑功能，科学家发现了滥用网络的青少年的大脑中有萎缩的灰质成分，随着使用网络的时间增长，萎缩的灰质部分有增大的趋势。专家称，这会影响他们的注意力以及记忆力，还有决策力。 Researchers took MRI brain scans from 18 university students, aged 19, who spent eight to 13 hours a day playing games online, six days a week. The students were classified as internet addicts after answering eight questions, including whether they had tried to give up using computers and whether they had lied to family members about the amount of time they spent online. The researchers compared them with a control group of 18 students who spent fewer than two hours a day on the internet. 研究员针对18名年龄为19岁的大学生进行脑部核磁共振成像分析，这些学生每周至少有6天玩网络游戏的时间从8小时到13小时不等，而这些孩子又被认定为不同程度上的“网络上瘾症”。此外，这些孩子被要求回答许多问答题，题目包括他们何时曾经试图“戒网”？或者是否对父母撒谎自己网上游戏的时间程度。专家拿这些“网瘾”孩子的数据与另一组相对比较少上网的孩子做对比。 |
