Restrictive means to reduce the spread of the COVID-19 pandemic have not only imposed broad challenges on mental health but might also affect cognitive health. Here we asked how restriction-related changes influence cognitive performance and how age, perceived loneliness, depressiveness and affectedness by restrictions contribute to these effects. 51 Germans completed three assessments of an online based study during the first lockdown in Germany (April 2020), a month later, and during the beginning of the second lockdown (November 2020). Participants completed nine online cognitive tasks of the MyBrainTraining and online questionnaires about their perceived strain and impact on lifestyle factors by the situation (affectedness), perceived loneliness, depressiveness as well as subjective cognitive performance. The results suggested a possible negative impact of depressiveness and affectedness on objective cognitive performance within the course of the lockdown. The younger the participants, the more pronounced these effects were. Loneliness and depressiveness moreover contributed to a worse evaluation of subjective cognition. In addition, especially younger individuals reported increased distress. As important educational and social input has partly been scarce during this pandemic and mental health problems have increased, future research should also assess cognitive long-term consequences.

减少 COVID-19 大流行传播的限制性手段不仅给心理健康带来了广泛的挑战，还可能影响认知健康。在这里，我们询问与限制相关的变化如何影响认知表现，以及年龄、孤独感、抑郁和限制的影响如何导致这些影响。51 名德国人在德国第一次封锁期间（2020 年 4 月）、一个月后以及第二次封锁开始期间（2020 年 11 月）完成了一项在线研究的三项评估。参与者完成了 MyBrainTraining 的九项在线认知任务和在线问卷调查，了解他们感知到的压力以及情境对生活方式因素的影响（影响）、感知到的孤独、抑郁以及主观认知表现。结果表明，封锁期间抑郁和受影响可能对客观认知表现产生负面影响。参与者越年轻，这些影响就越明显。此外，孤独和抑郁导致主观认知评价较差。此外，尤其是年轻人报告了更多的痛苦。由于在这次大流行期间重要的教育和社会投入在一定程度上缺乏，并且心理健康问题有所增加，未来的研究还应该评估认知的长期后果。
