认知功能是指执行不同难度任务的一套基于大脑的技能。由于人们在室内的时间较长，室内环境质量（IEQ）会影响居住者的认知功能，进而影响他们的学习和工作表现。以前的研究通常是考察IEQ对综合学习或工作表现的影响，而不是特定的认知技能。本文将IEQ分解为室内空气质量、热环境、照明、噪声和非光视觉五个因素。它将认知分为五类——注意力、感知、记忆、语言功能和高级认知技能——以便更好地理解IEQ和认知之间的关系。我们对66项重点研究进行了详细的人工综述，并通过分析8133项研究的关键词和摘要，采用共现分析法生成了IEQ与认知因素之间关联的景观。总的来说，结果表明，较差的IEQ条件并不总是与认知能力下降有关。然而，特定的IEQ因素对不同认知功能的影响是非常不同的。同样，特定的认知功能也会受到不同的IEQ因素的不同程度的影响。此外，研究结果表明相关文献存在广泛的不一致，特别是关于室内空气质量或热环境对认知的影响。此外，关键词共现分析还发现了近期文献中出现的更多的IEQ因素和认知功能。建议未来的研究探索导致我们在这里强调的不一致的因素。
Cognitive functions refer to the set of brain-based skills to execute tasks of various difficulty levels. As people spend substantial time indoors, the indoor environmental quality (IEQ) influences occupants’ cognitive functions and consequently their learning and work performance. Previous studies have commonly examined the effects of IEQ on integrated learning or work performance, rather than specific cognitive skills. The present review decomposes IEQ into five factors—indoor air quality, the thermal environment, lighting, noise, and non-light visual factors. It divided cognition into five categories—attention, perception, memory, language function, and higher order cognitive skills—to better understand the relationship between IEQ and cognition. We conducted a detailed manual review of 66 focused studies and adopted co-occurrence analysis to generate landscapes of the associations between IEQ and cognition factors by analyzing keywords and abstracts of 8133 studies. Overall, results show that poor IEQ conditions are but not always associated with reduced cognition. However, the effects of a specific IEQ factor on different cognitive functions are quite distinct. Likewise, a specific cognitive function could be affected by different IEQ factors to varying degrees. Furthermore, the results suggest extensive inconsistencies in the relevant literature, especially regarding the effects of IAQ or thermal environment on cognition. Additionally, the keyword co-occurrence analysis identified more IEQ factors and cognitive functions emerging in the recent literature. Future studies are recommended to explore the factors causing the inconsistencies that we highlight here.
