"While owning a phone does not make a person responsible for these violations, it does link us to the atrocities, and given the intimacy and constancy of these objects in our lives, the connection is ever-present and thereby disturbing" says Daniel Rothenberg, a lecturer at Arizona State University who presented a paper in July titled Is your cell phone linked to atrocities in Africa?
The purpose of that paper was to characterize color constancy of real, 3D objects across changes in the background and changes in illumination.
Such an indirect measurement of perceived similarity allowed a pure assessment of the constancy (or invariance) of object perception in rats, which would have been impossible to achieve otherwise, because of the impact of ongoing learning in standard tests of invariant recognition (see discussion in Sections 3.3.2 and 5.1).
Second, the examples used to support the proximal theory are unable to account for the perceived constancy of auditory features of distant objects.
We achieve perceptual constancy — the correlation of all the different appearances, the transforms of objects — very early, in the first months of life.
In 1963 Joyce and James set up a project, Young Children in Brief Separation, at the Tavistock Institute in London, to study the influence of variables on how a young child copes with separation – ie their understanding of object constancy, the quality of substitute care and the length of separation.
Recent research has started to investigate the attainment of object constancy in haptic object recognition, and how haptic and visual object recognition compare.
We therefore decided to compare the achievement of object constancy across vision and haptics for a different but commonplace source of input variation: size changes.
We suggest that the variation in results for the achievement of object constancy across previous studies may be due to the difficulty in equating object transformations such as orientation across vision and haptics.
