      Question 1

      The Optical Illusions app tests the brain’s ability to perceive and process visual images in a variety of ways. In several of these images, contrasting colors are placed in such a way as to disrupt perception. What is the color vision theory that is based on the idea that our visual systems are specialized to sense specific opposite pairs of colors?

      Question 2

      Candice is looking at a photograph on the Optical Illusions app. The image appears to show a normal adult woman touching the top of a building that is several stories high. This image distorts Candice’s ability to properly judge depth in a two-dimensional image by manipulating blank.

      Question 3

      In one optical illusion, a series of unconnected clouds appear to connect in such a way as to form a bridge. The “whole” that the brain forms from these “parts” is called a blank.

      Question 4

      Navzer is looking at a black-and-white image of a cat. As he focuses on the image, the cat suddenly becomes a bearded man’s face. The portion of the brain that some researchers believe is instrumental in receiving and perceiving faces is called the blank.

      Question 5

      Beth opens the Optical Illusions app and looks at an image of nine black dots arranged in such a way that Beth perceives that they form a cube. This tendency to fill in the missing parts of the image in order to form a whole is known as blank.
