Abstract
No sensory stimulus is an island unto itself; rather, it can only
properly be
interpreted in light of the stimuli that surround it in space and
time. This can result in
entertaining illusions and puzzling results in psychological and
neurophysiological
experiments. We concentrate on perhaps the best studied test case,
namely orientation
or tilt, which gives rise to the notorious tilt illusion and the
adaptation tilt after-effect.
We review the empirical literature and discuss the computational and
statistical ideas
that are battling to explain these conundrums, and thereby gain favour
as more general
accounts of cortical processing.
This version corrects various typographical errors. Also, the author
of references 17 and 70 was incorrectly listed as Li, Z when it should
be Zhaoping, L. This is the subject of an erratum in the journal.
