1) What is meant by perceptual constancy?
2) Choose either: size constancy, orientation constancy, shape constancy, lightness constancy, or color constancy (perceptual constancy is discussed in the lecture and the textbook. I discuss orientation constancy in the lecture. Demonstrations can be seen in Course Material and in my lecture). You might want to explore the famous “dress” controversy? Was it blue and gold or was it black and whatever!? What accounted for that? (Hint: Do some research on color constancy).
3) Describe this constancy in a paragraph. Again, you should do some research on how it is described in the field, and then armed with that information, present this information using your own words. Give evidence for it where possible.
4) What are the proposed ways that the visual brain achieves it? Again, what is the evidence?
5) What might happen to a person’s visual experiences of color, size, shape, orientation, motion, brightness, and other percepts if perceptual constancy did not occur? What would a person perceive? Can you find any evidence for this? (Note: This last part requires you do some research).
