Testing dynamical models of vision.
Most models of vision focus either on the spatial or temporal aspects of visual processing and neglect the other component. A variety of studies have shown, however, that spatial and temporal processing cannot easily be separated. The shine-through effect has proven to be a sensitive tool to study spatio-temporal processing. Two very different dynamical models, the 3D-LAMINART and the WCTM model, have explained the key aspects of the shine-through effect. Based on computer simulations Francis (2009) proposed a set of predictions based on stimulus variants of the shine-through effect that are crucial for both models. Here, we tested these predictions psychophysically. Both models fail to correctly predict the outcome of these experiments.
