Balling, J.D. and J.H. Falk, 1982. Development of visual preference for natural environments. Environ. & Behavior 14(1):5-28.
Subjects ranging from third graders to senior citizens participated in a visual preference survey. The subjects were asked to view slides from five natural landscapes; tropical rain forest, temperate deciduous forest, coniferous forest, savanna, and desert. They were asked if they would like to live in each area represented, and then asked if they would like to visit each area, rating their preferences on a 6- point Likert scale. The results were unable to provide sufficient evidence to support the hypothesis that humans have an innate preference for savanna-like settings. Only the elementary school children showed a significant preference for the savanna landscape.
