Public spaces must support a diverse group of users. Historically, designers of environments focused on the physical health and safety of users, particularly adults. In recent years, studies have emphasized the unique needs of special populations, some of which have led to policy making and an expanded concept of health and safety to include well_being. This has stimulated research focusing on understanding the psychological impact of the environment on adults, including their environmental preferences. Of all of the groups of users of public spaces, children have been the least considered. Typically, children are not part of the decision_making process, even when the designed environment is specifically for them, and adults often assume that children have identical environmental preferences. As the balance shifts and as roles change among the players involved in making the environment, children continue to be an underrepresented population among users, and little is known of their interior environmental needs and preferences. The objective of this study was to examine the interior built environment preferences of thirty 10-year old children from a moderately-sized southeastern American city. Three evaluative means were utilized. To determine overall preference, the children rated a set of colored slides of typical public spaces that a 10-year old child would commonly experience. To eliminate bias in their responses. care was taken to insure that all slides were of environments unfamiliar to the children. Further. Using an age appropriate semantic-differential scale developed by the investigators, the children again were asked to rate the slides to determine those environmental factors most influential in defining their preferences. To determine the relationship between preference and specific qualities of environmental space (volume, scale, enclosure, etc.), a series of computer_generated drawings focusing on these qualities were developed. The children sorted through the drawings to rank them according to preference for the various interior qualities. Findings will be analyzed and available for presentation at the conference. The research will describe the interior built environmental preferences of urban children, including an analysis of why the children have these preferences and what qualities of the built environment contribute to these preferences. Findings of this research will be of value to designers, architects, planners, and policy makers and will assist them in defending children's interests and in creating interior environments supportive of children's well_being.
