Abstract
SARS-CoV-2, the virus responsible for the Covid-19 pandemic, has been shown to have an impact on cognitive function, but the specific aspects of cognition that are affected remain unclear. In this Registered Report, we present a study aimed at further understanding the effects of SARS-CoV-2 on cognition, focusing especially on memory function, and to examine whether vaccination offers protection against long term cognitive symptoms of Covid-19. To this end, we will aim to replicate previous findings showing an effect of Covid-19 on memory, and will extend these findings by examining whether the effect varies as a function of memory type (item vs. associative) and stimulus type (verbal vs. pictorial). Moreover, we will compare cognitive functioning amongst vaccinated and unvaccinated individuals to explore the role of vaccination status in cognitive symptoms associated with Long Covid. Overall, the study will provide valuable insights into effects of SARS-CoV-2 infection on cognitive functions, and whether (and how) these are moderated by vaccination status. Comprehensive understanding of these aspects can inform and guideline public attitudes and policies related to Covid-19 and vaccination.
