Teenagers around the world can rejoice with the news that their brain deserves the blame when parents' orders go ignored while they tap on their smartphones. 在专注玩手机的时候，我们的大脑会自动“屏蔽”掉父母的唠叨——世界各地的青少年听到这个消息一定都会高兴地跳起来吧。 A new scientific study from the University College London has found that humans may be rendered temporarily deaf when they're simultaneously focusing on something visual. 伦敦大学学院最新的研究发现，人们在专注于眼前事物时，可能会出现短暂性的失聪症状。 Research found that the 13 volunteers experienced 'inattentional deafness' to the normal-volume sounds playing in the background as their visual tasks became increasingly difficult. 研究人员对13名志愿者进行了实验，发现他们在面对不断深入的视觉任务时，会经历“无意失聪”，即对正常音量的背景音置若罔闻。 |
