Time information in Poggendorff visual illusion: visual evoked potentials.
Using the component sets of the Poggendorff visual illusion as optical stimuli (comprising two horizontal and parallel segments intersected by two oblique segments), we recorded the respective visual evoked potentials (VEPs). Depending on the different delta t passing between the constitutive elements of the Poggendorff illusion, it was found that there was a greater latency of VEP components for the visual stimulus presentation sequence in which oblique segments are projected before horizontal segments.
