Make your response by clicking on the letter you are choosing. All the input to the left eye goes to the left half of the brain and all the input to the right eye goes to the right half of the brain. The crossover insures that stimulation arising from a common point in the visual field can be kept together in the brain even though it falls on different parts of the retina in the two eyes. Retinal image size of an object will vary greatly depending on our distance from the object, but we 'correct' for that variation and maintain consistency in size judgments.
Illusions are powerful indicators of principles of visual processing.
Sorry, not right. Cones are concentrated centrally and support detailed pattern perception. Cones are concentrated centrally and support detailed pattern perception. Rods are more widely distributed in the retina and help us detect movement. Sorry, not right.
