同时，看电视和使用社交媒体似乎并没有对智力产生积极或消极的影响。这项研究应该证明在关于多少屏幕时间适合幼小心灵的辩论中是有用的。研究人员在他们发表的论文中写道：“数字媒体定义了现代的童年，但它对认知的影响还不清楚，而且争论激烈”。
研究人员查看了 ABCD 研究中 9855 个孩子的屏幕时间记录，这些孩子都在美国，年龄在 9 或 10 岁。平均而言，这些青少年报告说他们每天花 2.5 小时看电视或在线视频，1 小时玩视频游戏，半小时通过互联网进行社交。
研究人员随后在两年后访问了这些儿童中超过 5000 人的数据。在这段时间里，研究中那些报告说花在视频游戏上的时间比标准时间多的人，其智商比平均水平高出 2.5 分。
智商的提高是基于孩子们在任务中的表现，包括阅读理解、视觉空间处理，以及一项专注于记忆、灵活思考和自我控制的任务。
值得注意的是，虽然这项研究只调查了美国的儿童，并且没有区分视频游戏的类型（移动游戏和游戏机游戏），但它仍然是对游戏和智商的一个有价值的见解–并且支持智力不是我们天生就有的一个固定常量的想法。
瑞典卡罗林斯卡学院的神经科学家托克尔-克林伯格（Torkel Klingberg）说："我们的结果支持这样的说法，即屏幕时间一般不会损害儿童的认知能力，而且玩电子游戏实际上可以帮助提高智力。
At the same time, watching TV and using social media do not seem to have a positive or negative impact on intelligence. This study should prove useful in the debate about how much screen time is suitable for young minds. “Digital media defines modern childhood, but its impact on cognition is unclear and hotly debated,” the researchers wrote in their published paper.
The researchers looked at the screen time records of 9855 children in the ABCD study, all in the United States, aged 9 or 10. On average, the teenagers reported that they spent 2.5 hours a day watching TV or online video, one hour playing video games and half an hour socializing via the Internet.
The researchers then interviewed data on more than 5000 of these children two years later. During this period, those in the study who reported spending more time than standard time on video games had an IQ 2.5 points higher than the average.
The improvement in IQ is based on children’s performance in tasks, including reading comprehension, visual spatial processing, and a task that focuses on memory, flexible thinking and self-control.
It is worth noting that although the study only surveyed children in the United States and did not distinguish between the types of video games (mobile games and console games), but it is still a valuable insight into games and IQ-and supports the idea that intelligence is not a fixed constant that we are born with.
Torkel Klingberg, a neuroscientist at the Karolinska Institute in Sweden, said: & quot; our results support the idea that screen time generally does not impair children’s cognitive abilities and that playing video games can actually help improve intelligence.
