Exploring the interplay of urban form and greenery in residents’ affective and cognitive responses

Abstract

Stress is a prevalent issue in modern cities, exacerbated by urban development and significantly affecting urban dwellers. While it is known that greenery can contribute to people’s wellbeing, it is unclear if it can mitigate the negative effects of urban development. In this study, we aim to explore the intricate dynamics between urban form and greenery to dissect their collective effect on human wellbeing, operationalized through physiological relaxation, preference, and emotional responses. The study employs an experimental study design using virtual reality technology to immerse participants (n=156) into residential neighborhood scenes, and measures affective and cognitive responses using skin conductance measures and a survey, respectively. In general, the findings confirm the critical role of urban greenery on affective and cognitive responses. Interestingly, we observe that this effect is highly dependent on the context and shows diverging patterns between different neighborhood types. In particular, in certain neighborhoods (popular, 60 s, and cooperative), greenery, no matter if species-poor or biodiverse, consistently improves preference and physiological relaxation. In contrast, urban centers and single-family residential areas may accommodate more biodiverse green spaces without compromising their existing high preference levels when compared to less affluent neighborhoods. The study concludes with a call for urban planning to cultivate equitable, green, and distinctively designed urban environments. This shift underscores the critical role of innovative urban design in improving the wellbeing of urban dwellers.
