The temporal dynamics of brightness filling-in

The temporal dynamics of brightness filling-in were studied through neural network simulation experiments conducted under visual masking stimulus conditions. Grossberg et al. have specified a filling-in model called the Boundary Contour System/Feature Contour System (BCS/FCS). The BCS generates boundary segmentation, while the FCS fills-in surface feature within these segmentation boundaries. Simulation experiments demonstrate that the model accurately predicts that area-suppression follows a U-shaped function of forward masking and demonstrate that the psychophysical findings of Paradiso and Nakayama [(1991) Vision Research, 31, 1221-1236] which they regarded as being against the BCS/FCS model, actually support the model.
