There is currently no robust method to evaluate how built environment design affects our emotion. Understanding emotion is significant, as it influences cognitive processes, behavior, and wellbeing, and is linked to the functioning of physiological systems. As mental health problems are becoming more prevalent, and exposure to indoor environments is increasing, it is important we develop rigorous methods to understand whether design elements in our environment affect emotion. This study examines whether the scale of interior built environments modulate neural networks involved in emotion regulation. Using a Cave Automatic Virtual Environment (CAVE) and controlling for indoor environmental quality (IEQ), 66 adults (31 female, aged 18-55) were exposed to context-neutral enclosed indoor room scenes to understand whether built environment scale affected self-report, autonomic nervous system, and central nervous system correlates of emotion. Our results revealed enlarged scale increased electroencephalography (EEG) power in the β bandwidth. Frontal midline low-γ and high-γ power were also found to increase with enlarged scale, but contrary to our hypothesis, scale did not modulate frontal midline power or lateralization in the θ or α bandwidths. We did not detect an effect of scale on autonomic indicators or self-reported emotion. However, we did find increased range in skin conductance response (SCR) and heart rate variability (HRV) to the built environment conditions. This study provides a rigorous empirical framework for assessing the environmental impact of a design characteristic on human emotion and suggests that measures of high-frequency oscillations may provide a useful marker of the response to built environment.
目前没有可靠的方法来评估建筑环境设计如何影响我们的情绪。理解情绪是很重要的，因为它影响认知过程、行为和幸福感，并与生理系统的功能有关。随着心理健康问题的日益普遍，以及人们在室内环境中的暴露增加，我们有必要开发严格的方法来了解环境设计元素是否会影响情绪。本研究考察了室内建筑环境的规模是否调节了参与情绪调节的神经网络。使用洞穴自动虚拟环境（CAVE）并控制室内环境质量（IEQ），66 名成年人（31 名女性，年龄 18-55 岁）暴露于中性的封闭室内场景中，以了解建筑环境规模是否影响情绪的自我报告、自主神经系统和中枢神经系统相关性。我们的结果表明，规模的扩大增加了脑电图（EEG）β频段的功率。还发现，额中线低γ和高γ功率也随着规模的扩大而增加，但与我们的假设相反，规模并没有调节θ或α频段的额中线功率或侧化。我们没有发现规模对自主指标或自我报告的情绪有影响。然而，我们确实发现皮肤电反应（SCR）和心率变异性（HRV）对建筑环境条件的范围有所增加。本研究为评估设计特征对人类情绪的环境影响提供了严格的经验框架，并表明高频振荡的测量可能是对建筑环境反应的有用标记。
