该综述发表在《世界精神病学》杂志上,由牛津大学、哈佛大学、西悉尼大学、国王学院和曼彻斯特大学的科学家共同撰写。其核查了诸多关于脑成像的研究,以得到互联网如何影响我们的大脑的一些主要假设。尽管这一研究结果并不是结论性的,但有证据表明,我们的网络生活方式正在改变大脑中与注意力、记忆力和社交技能相关的区域。
For example, one key study found that people who compulsively check their phones for messages and other notifications have reduced grey matter in certain areas of the prefrontal cortex that are associated with maintaining focus in the face of distractions. As a consequence, these individuals tended to perform worse on tasks designed to measure attention.
例如,一项重要的研究发现,强迫查看手机信息和其他通知的人,前额叶皮质某些区域的灰质有所减少,这些区域与面对干扰时保持注意力有关。因此,这些人往往在需要注意力的任务中表现得更差。
The impact of search engines has also led to speculation that we may begin to rely too heavily on the internet as a source of information, to the detriment of our own internal memory capacity. In support of this hypothesis, the authors point to a study which found that people tend to exhibit poorer recall of information found online as opposed to in an encyclopedia. Brain scans showed that this effect was correlated with reduced activation of the brain's ventral stream – a key memory retrieval system – when gathering information online.
