While the intrinsic bias hypothesis is proposed only for explaining distance biases, the angular expansion hypothesis provides accounts for a broader range of spatial biases.Abstract:
Two theories of distance perception—ie, the angular expansion hypothesis (Durgin and Li, 2011 Attention, Perception, & Psychophysics 73 1856-1870) and the intrinsic bias hypothesis (Ooi et al, 2006 Perception 35 605-624)—are compared. Both theories attribute exocentric distance foreshortening to an exaggeration in perceived slant, but their fundamental geometrical assumptions are very different. The intrinsic bias hypothesis assumes a constant bias in perceived geographical slant of the ground plane and predicts both perceived egocentric and exocentric distances are increasingly compressed. In contrast, the angular expansion hypothesis assumes exaggerations in perceived gaze angle and perceived optical slant. Because the bias functions of the two angular variables are different, it allows the angular expansion hypothesis to distinguish two types of distance foreshortening—the linear compression in perceived egocentric distance and the nonlinear compres- sion in perceived exocentric distance. While the intrinsic bias is proposed only for explaining distance biases, the angular expansion hypothesis provides accounts for a broader range of spatial biases.read more

Navigating in a three-dimensional world
TL;DR: In this paper, it is argued that the navigational problems in three dimensions are qualitatively as well as quantitatively different from those in two dimensions, and evidence suggests that, perhaps for this reason, horizontal and vertical space are processed separately in the vertebrate brain.

Aging and the perception of egocentric distance.
Zheng Bian,George J. Andersen +1 more
TL;DR: It is found that younger observers in general underestimated egocentric distance and showed foreshortening, and older observers judged more egOCentric distance than younger observers and did not show fore shortening.

TL;DR: Evidence was collected from 120 observers showing that directly manipulating physiological potential, while controlling for experimental demand effects, does not alter the perception of slant.

On the anisotropy of perceived ground extents and the interpretation of walked distance as a measure of perception.
TL;DR: It is concluded that walking measures are calibrated for perceived egocentric distance, but that pantomime walking measures may suffer range compression.

The Ecological Approach to Visual Perception
TL;DR: The relationship between Stimulation and Stimulus Information for visual perception is discussed in detail in this article, where the authors also present experimental evidence for direct perception of motion in the world and movement of the self.

Perceiving Layout and Knowing Distances: The Integration, Relative Potency, and Contextual Use of Different Information about Depth*
TL;DR: This chapter discusses three questions and suggests that list making has misled about space and layout and can begin to understand how those sources of information sharing the same-shaped functions across distances can help ramify judgments of layout by serving to correct measurement errors in each.
