Investigation on causal structure between IEQ and work performance mediated by arousal state

为了验证唤醒状态是介导室内环境质量（Indoor Environment Quality，IEQ）与工作绩效之间因果关系的人体反应之一，进行了3个主观实验。结果表明：（1）激发状态因IEQ而异;（2）工作绩效随能量激发的增加而提高，随紧张激发的增加而福尔斯;（3）简单工作对能量激发和紧张激发都有抑制作用，不同IEQ条件下产生的激发状态基本相同。而复杂的工作增加了精力充沛和紧张的唤醒，并且清楚地观察到由于IEQ而导致的唤醒状态的差异。

In order to verify that arousal state is one of the human responses mediating causal relationship between IEQ (Indoor Environmental Quality) and work performance, three subjective experiments were carried out. Results showed that (1) arousal state varies due to IEQ, (2) work performance improves with increase in energetic arousal and falls with increase in tense arousal, (3) simple work calm down both energetic and tense arousal and the resulting arousal states are almost the same under different IEQ conditions, while complex work increase both energetic and tense arousal and the differences in the resulting arousal states due IEQ are clearly observed.
