Figure-Ground Reversal
Figure-Ground Reversal problems (Rubin vase type) present a figure where you can see either one shape or another, depending on what you perceive as the figure (foreground) and what as the ground (background). The classic example is the Rubin vase: you can see two faces or a vase. The hidden shape is the alternate perception. These problems test your ability to reverse your visual attention.

Prerequisites
How to Solve Figure-Ground Reversal Problems
Step 1: Look at the figure. You will initially see one dominant shape (the figure).
Step 2: Consciously try to see the background areas as the figure instead.
Step 3: The hidden shape is the one formed by the negative space (the background).
Step 4: In a vase/faces illusion, the hidden shape is the vase if you first saw faces, or the faces if you first saw the vase.
Step 5: The hidden shape may be a vase, a face, a bird, a butterfly, or a letter.
Step 6: Once you perceive the alternate shape, identify it.
Step 7: Select the answer option that matches the alternate perception.
Example Problem
Example: A classic Rubin vase figure. You initially see a white vase. The hidden shape is formed by the black areas on the sides. Solution: Step 1: Initially see a white vase. Step 2: Shift focus to the black areas on the left and right. Step 3: The black areas form two faces in profile, facing each other. Step 4: The hidden shapes are the two faces. Answer: Two faces
Pro Tips & Tricks
- The hidden shape is always the negative space of the dominant shape.
- In symmetrical figures, the hidden shape is often a face or an animal.
- The figure is usually designed so that both interpretations are equally valid.
- Try squinting or defocusing your eyes to see the alternate shape.
- Look for repeating patterns in the negative space; they often form recognizable objects.
