Some form of preference rating has been the focal dependent variable in numerous environmental evaluation studies. An assumption guiding much use of the preference rating is that it reflects innate sensibilities regarding what is important for effective functioning and survival, and so for health and well-being. To date, evidence of the tenability of this assumption has come largely from two types of empirical study. One includes environmental evaluation studies which have examined associations between preference ratings and variables that have implications for functioning and survival, such as coherence, mystery, and environmental content. A consistent finding of such studies is that scenes with natural environmental contents such as vegetation and water are associated with greater preference than scenes lacking in natural contents. The second type of study includes those concerned with restorative environment experiences, in which environmental content has been manipulated in testing for effects on variables that more directly represent health and well-being, such as emotional states, attentional performance, and blood pressure. Such experiments have manipulated environmental content in a coarse_grained fashion, as a natural versus urban comparison, and tell us that the natural environmental contents associated with relatively, higher preferences are of a kind with those contents that engender greater restoration in experimental subjects. Although the two types of studies in combination corroborate the assumption of a relationship between environmental preference and well-being. more direct evidence remains to be provided. One approach to developing this evidence involves a closer working integration of environmental evaluation and restorative environments research. 'he present paper discusses the theoretical bases for such an integration and presents the results of studies which bear on that integration.
