Abstract : In order to assess the effects of long-term respirator wear on cognitive performance and signal detection, nine subjects continuously performed various computer controlled tasks under non-exercise conditions during two 10 hr days one with and one without (control) wearing a respirator. Cognitive tasks assessed speed of information processing, language skills, rapid visual scanning, recognition memory, and divided attention. Subject anxiety levels were also assessed. Cognitive performance did not differ significantly between respirator and control trials and was not changed over time. In general, mean decision-making times were slower during respirator wear compared to control, but the differences were not significant.
