An hour and a half after waking, early birds and night owls were equally alert and showed no difference in attention-related brain activity. But after being awake for 10 and a half hours, night owls had grown more alert, performing better on a reaction-time task requiring sustained attention and showing increased activity in brain areas linked to attention.翻译下大意:
在醒来后的1个半小时以后,早起的人和夜猫子在注意力和警觉性方面并没有什么差异。但是在醒来后10个半小时以后,夜猫子相比具有更高的警觉性,他们在进行需要持续注意力的任务时反应更快、效果更好,并且其与注意力相关脑部区域活动明显增强。当然,如果有另外一个研究跳出来说反对的话,我们也并不会吃惊。所以对上面的研究结果,我们要高举马克思主义的旗帜,采用科学实践发展观,用发展的眼光、用怀疑的态度,在实际生产活动中对这个结果进行验证。但对于早鸟和夜猫子的长期以来的讨论,这个研究结果是个有意思的补充。
