Experiments were conducted to determine the effects of different concentrations of ozone at 0.00, 0.25, 0.50, and 0.75 parts/million (ppm) on sustained visual and auditory attention tasks (vigilance performance). When the rate of signals to nonsignals was low, approximately 1 out of 30, ozone in concentrations as high as 0.75 ppm did not alter performance to either visual or auditory tasks. However, when the ratio of signals to non-signals was increased, a deficit in performance beyond that of the normal vigilance decline was observed during the 0.75 ppm ozone exposure. However, no changes in false positive responses occurred. The results were interpreted within the framework of an arousal hypothesis, suggesting that high concentrations of ozone may produce overarousal.
进行了实验，以确定百万分之0.00、0.25、0.50和0.75不同浓度的臭氧对持续视觉和听觉注意力任务（警觉表现）的影响。当信号与非信号的比率较低时，约为30分之一，高达百万分之0.75浓度的臭氧不会改变视觉或听觉任务的表现。然而，当信号与非信号的比率增加时，在百万分之0.75臭氧暴露期间，观察到表现缺陷超过正常警觉下降。然而，误报反应没有变化。结果在唤醒假说的框架内进行了解释，表明高浓度的臭氧可能会产生过度唤醒。
