Responses to Six Major Terrestrial Biomes in Terms of Scenic Beauty, Preference, and Restorativeness

Abstract

This study examined 274 college students' psycho-physiological responses to the six major terrestrial biomes (desert, tundra, grassland, coniferous forest, deciduous forest, and tropical forest), while taking into account the influences of three perceived physical variables (complexity, openness, and water features) presented in the biomes. The purpose of the study was to examine which specific natural setting can evoke the most positive reactions from people. ANCOVA tests and post hoc comparisons using the setting scores across the participants' data on the responses to 48 biome slides regarding scenic beauty, preference, the Short-version Revised Perceived Restorativeness Scale and the Short-version Revised Restoration Scale were performed. The results indicated that tundra and coniferous forest were the most favored biomes, whereas desert and grassland were the least favored. These findings appeared to support the forest hypothesis rather than the long-held savanna hypothesis. In addition, the results of multiple regression analyses indicated that the three perceived physical factors explained 9% more variance of the respondents' reactions than the biome classification. This finding suggested that a nonhabitat-specific approach to environmental responses holds more promise than a habitat-specific approach.
