"This paper is one of a series of publications examining the connections among changes in social and cultural values, individual behavior, and space in residential settings. In the first stage of research, a feminist theoretical perspective and the method of content analysis were joined to analyze house plans determining links between women's changing roles and noticeable changes in house plans. In Stage II, a more general sociological theoretical perspective on gender was combined with the use of threedimensional scale models and an interview schedule to examine more directly the interaction of personal values, behavior and spatial preferences. Because the findings of Stage II provided research hypotheses but failed to fully explain the reciprocal interaction between people and space, the theoretical perspective and method were refined for a more detailed Stage Ill study. Here we joined theoretical perspectives from architecture and environmental social -psychology in addition to research methods for exploring social and spatial issues at the interior level of domestic space. The data for Stage Ill, and for this paper, are based on a sample of 100 couples from building permits for new houses, renovated houses and additions between 1985-1989 in a southeastern Standard Metropolitan Statistical Area of the US. An hour long session was conducted in each couple's home using an interview schedule and six previously constructed 1/12 scale kitchen models, and a self-administered questionnaire. We investigated linkages between interior space and gender by contrasting and comparing women's and men's assessment of kitchen spatial openness. Physical spatial characteristics were quantified using 3D scale models and the interview schedule. Each scale model varied by a measurable degree in terms of the following design characteristics: 1) amount of wall enclosure; 2) size of work triangle (suitable for one person or two persons) ; 3) inclusion of an eating table or counter in the kitchen; and 4) visibility out of the kitchen to the dining and seating areas. All six scale models had the same total square footage. Three kitchens were coded as "single-function" kitchens; three were coded as "multi-function kitchens." Wall enclosure was incrementally changed from closed to open in both single-function and multi-function kitchens. Social variables for both men and women were assessed through a self-administered questionnaire: we compiled social variables for their occupations, number of children at home, gender attitudes (traditional or modern), sharing of both traditionally female and male household tasks, and a psychological self-monitoring scale. The substantive problem addressed in this paper is the spatial, or architectural, conditions explaining why persons choose either mult- or single-function kitchens. The theoretical importance of the problem lies with the cultural meanings attached to these contrasting choices. The theoretical argument in the literature is that persons opting for open and multi-function kitchens tend to favor gender egalitarianism and to behave in a more egalitarian fashion. Conversely, persons choosing closed and single-function kitchens tend to be more gender traditional both in norms and behavior. A prior analysis of our data, using multiple regression, added validity to that theoretical proposition by identifying the social variables accounting for kitchen openness. In this paper, we take our empirical investigations one step further by utilizing discriminate function analysis to classify respondents as preferring multi- or single-function kitchens based on spatial as well as social variables. Preliminary findings suggest that women can be classified correctly 74 per cent of the time in terms of their responses to seven spatial and social variables. Men can be correctly classified 79 per cent of the time in terms of their responses to eleven spatial and social variables. We shall continue our statistical analyses with the aim of refining and elaborating our preliminary findings. The final version of this paper will be based on those refined data. The paper will close by theoretically linking these findings to our past work, and to the general problem of the connections between interior space and the changing sociocultural environment."
