Abstract
By stating the subject in this way, I have more or less taken up the position of the devil’s advocate. Amidst these physiologically (exclusively bottom-up) oriented papers, I will defend the viewpoint that many perceptual phenomena cannot satisfactorily be explained by such bottom-up processes. The first statement I would make is directed towards the possibly misleading role of physiology, when simple and successfully applicable mechanisms have been found. An example is lateral inhibition. There is hardly a mechanism which has more strongly influenced developments in perceptual theories: contrast, Mach-bands, spatial contrast transfer functions, Marr’s theory of zero-crossings and so forth. There is no doubt that contrast is a very important phenomenon, but is it so important that other phenomena, which seem of a contradictory nature, must be ignored or neglected?
