摘要

Exposure to green space provides restoration from depleted emotional and cognitive resources, but characterizing what green space exposure is difficult. Using immersive virtual environment (IVE) stimuli, we are able to simulate green spaces in urban environments, to better understand factors influencing green space benefits. Little is known about the attributes of green spaces that support mental restoration and the mechanisms through which green spaces promote restoration. We examine the effects of arrangement and density of vegetation on (1) perceived restorativeness and (2) whether perception of safety mediates the effects of these attributes on perceived restorativeness. 360° panoramas taken from two urban settings (plaza and park) were manipulated for vegetation arrangement (the number of vegetated segments along a boundary of a square shaped area) and density (the number of trees in each segment) to generate 18 IVE stimuli. The experiment had a 3 × 3 × 2 mixed factorial design with density (one, three and six trees per segment) as between-subjects treatment, and arrangement (1-, 2- and 4-sided) and setting type (park and plaza) as within-subjects treatments. Using a head-mounted display, participants (N=87) rated IVEs on perceived restorativeness and perceived safety. Vegetation arrangement affected perceived restorativeness across both setting types, but in opposite direction. More enclosed arrangements (4-sided) in plaza setting were perceived as more restorative, whereas in park setting the same arrangements significantly reduced perceived restorativeness. Vegetation density and arrangement significantly interacted with each other and with setting type to affect perceived restorativeness and perceived safety. Perceived safety mediated the effects of vegetation density and arrangement on restorativeness. IVEs can be used to explore specific aspects of broad exposures to better characterize impacts of the environment on human health.
