Sequential viewing of 2 orthogonally related gratings produces an afterimage related to the first grating (Vidyasagar, Buzas, Kisyarday & Eysel, 1999; Francis & Rothmayer, 2003). The authors investigated how the appearance of the afterimage depended on the relative orientations of the 2 stimulus gratings. They first analyze the theoretical explanation of the appearance of the afterimage that was proposed by Francis and Rothameyer (2003). From the analysis, they show that the model must predict a rapid drop in afterimage occurrence as the gratings deviate from orthogonal. They also show that the model predicts that the shape of the afterimage should always be orthogonal to the second grating. They then report on 2 experiments that test the properties of the model and find that the experimental data are strikingly different from the model predictions. From these discrepancies they identify the key deficits of the current version of the model.
