Nature:还在边看电脑边玩手机?小心记忆力减退

2020-10-30 haibei MedSci原创

注意力失误部分解释了为什么我们会在当下记住或忘记,以及为什么有些人比其他人记得更好。值得注意的是,较重的媒体多任务处理与注意失误和遗忘的倾向有关。

随着数字媒体和技术的爆炸式发展,学者、教育工作者和公众对 "注意力经济 "在我们生活中所扮演的角色的呼声越来越高。当前数字文化的兴起与长期以来的科学问题不谋而合,即为什么人类有时会记住,有时会忘记,以及为什么有些人比其他人记得更好。

在这里,研究人员在Nature杂志发文,研究在当下,跨个人和作为日常媒体多任务的功能时,自发的注意力失误是否与记忆负相关。利用脑电图和瞳孔测量的注意力,研究人员记录了八十名年轻的成年人(平均年龄,21.7岁)执行目标导向的偶发编码和检索任务。使用基于任务的和问卷测量进一步量化特质级持续注意。

使用试验到试验的检索数据,研究人员发现,在记忆前的时刻,通过后方α功率和瞳孔直径测定的强直性失误的注意力,与目标编码和记忆的神经信号的减少,以及行为遗忘相关。特质水平的注意力失误的独立测量介导了失误的神经测定与记忆表现之间的关系,以及媒体多任务与记忆之间的关系。

注意力失误部分解释了为什么我们会在当下记住或忘记,以及为什么有些人比其他人记得更好。值得注意的是,较重的媒体多任务处理与注意失误和遗忘的倾向有关。
