Abstract
Instead of asking observers to align one whole Poggendorff transversal segment with the other, one can require them to align either the near lip or the far tip of one transversal with the other, whole transversal. The experiment described here shows that when this is done, near tip errors exceed far tip errors. This rinding seems to pose difficulty for most current theories of the Poggendorff effect.This publication has 9 references indexed in Scilit:
