ABSTRACT
In our everyday experience, visual consciousness seems to consist of a single, unified visuospatial world in which we see a multitude of different objects located in threedimensional space. Each object consists of a unique combination of different visible features, such as colour, shape and motion, coherently bound together into a single package: the object as we perceive it. Thus, our visual world appears to have global spatial unity (the unity of the overall visual space where the objects seen are located) and local unity (the unity of each separate object that is perceived). All this unity and coherent organization of the perceptual world is perfectly natural and totally effortless for us. We simply open our eyes and the visible world appears immediately before our eyes, as solid and real as anything we could ever imagine.
