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

为了验证唤醒状态是调节室内环境质量（IEQ）与工作绩效之间因果关系的人类反应之一，本研究进行了三个主观实验。结果表明：(1)唤醒状态因IEQ的不同而不同；(2)工作绩效随能量唤醒的增加而提高，随紧张唤醒的增加而下降；(3)简单工作使能量唤醒和紧张唤醒平静下来，不同IEQ条件下的唤醒状态基本相同，而复杂工作使能量唤醒和紧张唤醒同时增加，IEQ导致的唤醒状态差异明显。

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.
