Negative afterimages occur when our photoreceptors in our retina, known as rods and cons, adapt to overstimulation and lose sensitivity. See Motion aftereffect. This can happen when one looks at a plain white wall. We explore attentional effects on afterimages in the framework of the FACADE model of visual perception.

A possible interpre- tation assuming a slower disappearance of the after- effects caused by the bright regions of the fundamen- tals is excluded by the fact that the afterimages were similar and negative with respect to the virtual grat- ing and a corresponding stationary grating; an explanation based on decay processes would predict them opposite since in counterphase afterimages in after effects fundamentals the objectively intense regions coincide with subjectively dark regions (see Fig. a visual image or other sense impression that persists after the stimulus that caused it is no longer operative. People see the opposite colors or a negative image because staring at one color for an extended period will fatigue the eyes rods afterimages in after effects & afterimages in after effects cones.

These orientationally based afterimages are sometimes called complementary after-images (CAIs) to afterimages in after effects indicate that the shape of the after-image is, in some sense, the orthogonal complement of the inducing im-age. , & Grabowecky, M. However, it is not just adaptation to motion that produces aftereffects. They are often very brief, lasting less than half a second.
