Abstract
In 1988 Greene noted, if a straight pair of obliques are drawn outside of two orthogonal lines, the segments appear to be angled slightly on e relative to the other. This illusion, designated as ''corner Poggend orff,'' is different from the Poggendorff effect (the two obliques see m to lie on a parallel path). The results of the present experiments ( N = 76 students) suggest that the general conditions for the corner Po ggendorff are similar to those for the Judd illusion.
