COVID-19 infection does not seem to affect cognition in college students

Emerging evidence indicates that COVID-19 damages the central nervous system and thereby might engender long-term cognitive impairment. Self-reports and some measures of cognitive ability suggest that long COVID can lead to substantial and frightening detriments in cognition. To further explore this issue, we used data from university courses on cognitive psychology where students participated in classic experiments that measure various aspects of cognition. Across 24 experiments we compared cognitive performance of students who had contracted COVID-19 against those who were uninfected. Using Bayes Factor analyses, we assessed both differences and invariances in performance as a function of infection status. Our findings suggest that COVID-19 infection has hardly any impact on cognition for university students.
