On covariant non-constancy of distortion and inversed distortion tensors [PDF]
The paper deals with covariant constancy problem for tensors and pseudotensors of an arbitrary rank and weight in an Euclidean space. Requisite preliminaries from pseudotensor algebra and analysis are given.

Size Constancy Mechanisms: Empirical Evidence from Touch
Several studies have shown the presence of large anisotropies for tactile distance perception across several parts of the body. The tactile distance between two touches on the dorsum of the hand is perceived as larger when they are oriented ...

Adaptive colour constancy algorithm using discrete wavelet transform [PDF]
The colours of chromatically homogeneous object surfaces measured by a sensor vary with the illuminant colour used to illuminate the objects. In contrast, colour constancy enables humans to identify the true colours of the surfaces under varying ...

The effect of background and illumination on color identification of real, 3D objects
For the surface reflectance of an object to be a useful cue to object identity, judgments of its color should remain stable across changes in the object's environment. In 2D scenes, there is general consensus that color judgments are much more stable

At first pass, colour constancy occurs when one sees a thing in one’s environment to have a stable colour despite differences in the way it is illuminated at a time (simultaneous constancy) or over time (successive constancy).

Interracial contact and racial constancy: A multi-site study of racial intergroup bias in 3-5 year old Anglo-British children [PDF]
This paper examined the influence of interracial contact and racial constancy on the racial intergroup bias of young Anglo-British children. This multi-site study was conducted in areas of Great Britain that varied in terms of racial diversity. The study
