Cognitive performance
An additional potential impairment from wearing masks concerns cognitive performance, which is why a math and a spelling test was carried out to simulate office work. No negative impact of mask wearing on the cognitive performance was detectable in accordance with other studiesOur finding that the number of errors in the math test was lower in the second measurement both with and without mask can probably be attributed to a training effect. The consistently longer reaction time in the math test compared to the spelling test is probably due to a higher complexity of the tasks. In agreement with Haber et al.
