Card 40 / 50: Take a look at the following figure. If you close your left eye and focus on the × while slowly moving the paper away from your face, what will happen and why?
A) The picture will disappear because it will only be seen by the periphery of your eye, which includes only rods and no cones, and rods are unable to detect images like a picture.
B) The picture will disappear when it lands on the part of your eye where ganglion cell axons come together to form the optic nerve, because there are no photoreceptors there.
C) The picture will disappear when it lands on your fovea, because there are only cones in the fovea and cones cannot detect a picture that is in black and white.
D) The picture will appear to move, because it will be seen by the rods in the periphery of your retina, and rods are more sensitive to motion.
