The Jastrow illusion is a common visual illusion, this model is a demonstration based on it, using less material and full of fun, you can try printing and downloading it.
Here is a specific introduction about it:
- Definition and manifestation
- Two curves of equal length, the lower one looks longer than the upper one.
- Two identical fan-shaped rings, the lower fan-shaped ring looks larger than the upper one.
- Discoverer: Discovered by American psychologist Joseph Jastrow in 1889.
- Cause: When comparing the sizes of objects, people unconsciously use the adjacent sides of two objects for comparison, and then compare the longer side with the shorter side, the brain will distinguish the object with the longer side as the larger one.
- Practical application cases: In episode 655 of the Japanese anime Detective Conan, titled “Poison and Illusion Design (illusion)”, the murderer used the Jastrow illusion to place poison on the seemingly larger piece of cake when arranging the cakes, inducing the hungry president's son to choose that piece.
