The mental spatial models are mental representations that preserve information about objects and the spatial relations among them and are updated as new information comes in (p 6). Through our bodies, we perceive and act on the world around us and learn about the consequences of our actions. One way that we view and think about bodies is as objects. Common objects can be referred to at several levels of abstraction (p 5). Bodies are a privileged object for humans. Unlike other objects, they are experienced from inside as well as outside (p 4).
People form long-term representations of areas, but long-term knowledge of specific spaces may vary considerably in completeness (p 14). People...code location in terms of distance and direction information within a region, taking its shape and edges as a frame of reference (p 17).
