How does territorial functioning operate in settings where people live? This is the main question addressed in this chapter. A range of interior residential settings will be examined, spanning intact households, dorm settings, institutional residential settings, and experimental groups in isolation.

These various sites share three characteristics. (1) For a period of time, small groups, ranging in size from two to more than a dozen, live in these settings; they take up residence there and share space. It is there that the “strongest” territories exist. These spaces represent the core of the group's spatial activity system. (2) Interior residential settings are strongly multifunctional. (3) And, in these settings, co-occupants have frequent contact over a period of time. The objective diversities of the settings examined here are outweighed by the similarities in subjective significance and individual and group functioning.

Investigating territorial functioning in interior residential settings is frustrating for two reasons. First, the settings in question are highly private, causing operational as well as ethical problems for researchers (see the following box). Consequently, there is a paucity of solid data for some of the settings considered. Second, territorial functioning is often latent one is not aware of it unless changes impinge (see Figure 7.1). This submerged nature of territorial functioning makes its examination all the more difficult.
