Although the literatures on human spatial cognition and animal
navigation often make distinctions between egocentric and allocentric (also
called exocentric or geocentric) representations, the terms have not
generally been well defined. This chapter begins by making formal
distinctions between three kinds of representations: allocentric locational,
egocentric locational, and allocentric heading representations. These
distinctions are made in the context of whole-body navigation (as
contrasted, e.g., with manipulation). They are made on the basis of
primitive parameters specified by each representation, and the
representational distinctions are further supported by work on brain
mechanisms used for animal navigation. From the assumptions about
primitives, further inferences are made as to the kind of information each
representation potentially makes available. Empirical studies of how well
people compute primitive and derived spatial parameters are briefly
reviewed. Finally, the chapter addresses what representations humans may
use for processing spatial information during physical and imagined
movement, and work on imagined updating of spatial position is used to
constrain the connectivity among representations...
