Abstract
The Poggendorff illusion is one of the most exhaustively studied illusions. Can it be revived
as an interesting problem? Perhaps by moving it to a slightly different domain. Here, we consider
the occlusion of a subjectively linear ramp of tonal values. In a simple experiment, we find results
closely resembling those of the geometrical Poggendorff. Yet, the “explanations” offered for the latter
hardly apply to the former case. Depending upon one’s perspective, this may be taken to “revive” the
Poggendorff illusion.
