搜索引擎的影响也引来了质疑,即我们可能开始过度依赖互联网作为信息来源,而损害了我们自己内部的存储能力。为了支持这一假设,作者指出,一项研究发现,与百科全书相比,人们对在线信息的记忆力往往较差。脑部扫描显示,这种影响与在线收集信息时大脑腹侧流(一种关键的记忆检索系统)的激活程度下降有关。
Such a finding raises the possibility that online learning may fail to sufficiently activate key brain regions required for long-term memory storage.
这一结果提高了一种可能性,即在线学习可能无法充分激活长期记忆存储所需的关键大脑区域。
Social media networks also appear to be transforming the ways in which our brains’ social centers work. For instance, one study found that the number of Facebook friends a person has determined the volume of grey matter in the right entorhinal cortex, which has previously been associated with the ability to associate names and faces.
社交媒体网络似乎也在改变我们大脑社交中心的运作方式。例如,一项研究发现,一个人在Facebook上的好友数量决定了他右内嗅皮层中灰质的含量,该部分曾与人的名字和面孔的关联能力有关。
This effect is likely to be caused by the fact that social media encourages people to maintain large numbers of weak social connections, requiring an increased ability to put names to faces. Prior to the advent of social media, people tended to have deeper relationships with a smaller network of people, and therefore required different adaptations within the brain’s social regions.
