COVID-19 pandemic has posed an unprecedented challenge in front of the world contributed mostly by social distancing and lockdown. Among several other effects this pandemic has wreaked havoc on the psychology and cognition of people across the globe. In this paper we attempted to find out the impact of lockdown and social isolation on the cognition and emotion of young healthy adults with high education (n=43) by means of a questionnaire sent through email. We found that more than 50% of the participants had some kind of emotional or cognitive (dysexecutive) symptoms, as calculated through emotional symptom index (ESI) and cognitive symptom index (CSI). The correlation between cognitive and emotional symptoms was also found to be moderately strong (0.59). Although it is a pilot study and larger samples are required to draw firm conclusion, the results argue in favor of a negative impact on the cognition and emotion of healthy educated young people caused by the COVID-19 related lockdown. It can be conjectured that, if taking an older sample with a lower education, emotional and cognitive changes would be more evident.

与COVID-19相关的锁定对认知和情绪的影响：一项初步研究

COVID-19大流行在世界面前提出了前所未有的挑战，这主要是由于社会疏远和封锁造成的。这种流行病还给全球各地的人们的心理和认知造成了严重破坏。在本文中，我们试图通过电子邮件发送的调查表，找出锁定和社会隔离对受过高等教育的年轻健康成年人（n = 43）的认知和情绪的影响。我们发现，超过50％的参与者具有某种情绪或认知（执行不良）症状，通过情绪症状指数（ESI）和认知症状指数（CSI）计算得出。认知和情绪症状之间的相关性也被发现是中等强的（0.59）。尽管这是一项试点研究，需要更大的样本才能得出肯定的结论，结果表明，与COVID-19相关的锁定会对健康的受过教育的年轻人的认知和情绪产生负面影响。可以推测，如果接受教育程度较低的年龄较大的样本，情绪和认知的变化将更为明显。
