A study on temporal properties of illusory-surface perception by using the Poggendorff configuration

Temporal properties of illusory-surface perception were investigated by using the probing method of the Poggendorff configuration. Real lines and an opaque illusory surface composing the Poggendorff configuration were used and presented in various displaying sequence. We referred that illusory surface was necessary to keep remained for perceiving till the afterimage of real lines disappeared. We believe that the Poggendorff configuration could be a clue for better understanding of surface perceiving mechanism in human visual system.
