Keywords: Spatial orientation; spatial updating; egocentric; reference frame; theory; model; interference; framework Modeling spatial orientation processes The goal of this manuscript is to develop a theoretical framework that integrates two current theories of spatial orientation: May (2004) proposed that the difficulty of imagined perspective switches is caused, at least in part, by interference between the sensorimotor and the to-be- imagined perspectives. Riecke & von der Heyde (2002) developed a theoretical framework that is based on a net- work of logical propositions (i.e., necessary and sufficient conditions). They proposed that automatic spatial updating can only occur if there is a consistency between the ob- server’s concurrent egocentric reference frames (e.g., medi- ated by real world perception, virtual reality [VR], or imag- ined perspectives, see Fig. 1, bottom left). We propose that the underlying processes are the same, in the sense that a consistency between egocentric representa- tions (Riecke & von der Heyde, 2002) is equivalent to an absence of interference (May, 2004). Whenever the current egocentric representations of the immediate surroundings are consistent, there should be no interference (cf. Fig. 1, top right). According to Riecke & von der Heyde (2002), this state enables automatic spatial updating. We propose that this lack of interference might also be able to explain other important phenomena, such as the relative ease of adopting a new perspective after being disoriented. Con- versely, interference (inconsistency) between the primary, embodied egocentric representation and a to-be-imagined (e.g., experimentally instructed) egocentric representation implies the difficulty of adopting a new perspective (cf. Fig. 1, top left). We posit that such interference or inconsistency also explains the difficulty people have in ignoring bodily rotations. Integrating logical and information flow represen- tations in one coherent framework not only provides a uni- fied representation of previously seemingly isolated findings and theories, but also fosters a deeper understanding of the underlying processes and enables clear, testable predictions.
