Explanation: A "blind spot" is the place in the visual field that corresponds to the lack of light-detecting photoreceptor cells on the optic disc of the retina where the optic nerve passes through. When his head falls into our blind spot, our mind makes sense of the mismatch by replacing his head with the yellow background. When he raises a black bar across his body, our mind jettisons the background to avoid splitting the bar into two discontinuous halves.
