Why do preferences differ between scene types?

Groups of subjects judged one example of two different types of outdoor sce nes on each of the items of the Perceived Restorative Scale, on two prefere nce scales and a familiarity scale. It was argued that the previously demon strated large variations in preference between different types of scenes we re the result of participants using the restorative value of a scene as an implicit frame of reference for the preference judgment. Preference and the Perceived Restorative Scale score correlated .31, whereas familiarity and the Restorative Scale correlated .31, and preference and familiarity correl ated .32. This result supports the hypothesis regarding the use of the rest orative value of a scene as an implicit frame of reference for preference j udgments. It is further argued that variations in the preference and restor ative value of scenes may be associated with fractal geometry.
