abstract = {Size adaptation describes the tendency of the visual system
to adjust neural responsiveness of size representations
after prolonged exposure to particular stimulations. A
larger (or smaller) adaptor stimulus influences the
perceived size of a similar test stimulus shown
subsequently. Size adaptation may emerge on various
processing levels. Functional representations of the adaptor
to which the upcoming stimulus is adapted may be coded early
in the visual system mainly reflecting retinal size.
Alternatively, size adaptation may involve higher order
processes that take into account additional information such
as an object's estimated distance from the observer, hence
reflecting perceived size. The present study investigated
whether size adaptation is based on the retinal or the
perceived size of an adaptor stimulus. A stimulus' physical
and perceived sizes were orthogonally varied using perceived
depth via binocular disparity, employing polarized 3D
glasses. Four different adaptors were used, which varied in
physical size, perceived size, or both. Two pairs of
adaptors which were identical in physical size did not cause
significantly different adaptation effects although they
elicited different perceived sizes which were sufficiently
large to produce differential aftereffects when induced by
stimuli that physically differed in size. In contrast, there
was a significant aftereffect when adaptors differed in
physical size but were matched in perceived size. Size
adaptation was thus unaffected by perceived size and
binocular disparity. Our data suggest that size adaptation
emerges from neural stages where information from both eyes
is still coded in separate channels without binocular
interactions, such as the lateral geniculate nucleus.},
