The checker shadow illusion is my favorite illusion, because even though when I know exactly what's going on it still appears otherwise. The checker shadow illusion is an image of a checkerboard of grey and dark grey squares and in one corner there is a cylinder casting a shadow across the board. Inside that shadow the checker board continues its pattern, and so the lightest color square inside the shadow area appears to look like the same color as the lightest shade outside of the shadow area. Yet somehow that light colored square in the shaded area is actually the same color as the darkest colored square on the outside of the shaded area.
One of two tricks that makes us perceive the squares local contrast. The squares surrounding the square in the shadow are darker so the center square appears more similar to the lighter squares outside of the shadow.
The second trick is because of how we see shadows. Shadows have soft edges and so we ignore the gradual darkening of objects while the paint edges have sharp edges that are more distinct.
I liked this illusion a lot, mostly because it was life size. I've watched it a few times and I still cannot wrap my brain around the fact that those tiles are the same color.
The psychology of Perception involves the interaction of our senses and our conscious mind. Perception is involved in every aspect of our lives as we make decisions and judgments based on what we experience. If you study diligently you will leave this course with a broad understanding of sensation and perception. From this general understanding you will be able to further investigate areas of interest by means of literature review and research on specific topics.
I like this illusion. It is refreshing that one can recreate this illusion on a life sized model.
