Answer the following question in 3-4 complete sentences. Explain what you see in the image on the left, verses the image on the right. What a person sees when looking at the above two pictures depends on what concept?

Answer:

In the image on the left, the black area can look like a vase, while the white areas on either side look like two people facing one another. In the image on the right, the colors are inverted, so the vase appears white and the faces appear black. What a person sees depends on figure-ground perception, or which part of the image they interpret as the figure and which part as the background.
