Facts about Müller-Lyer Illusion
- 06
Measurements of the Müller-Lyer illusion show the effect persists at magnitudes of 10-20 percent line-length difference even in highly trained observers who intellectually understand the deception.
- 05
Neurological research suggests the Müller-Lyer illusion persists even when observers are fully aware they are being deceived, demonstrating its automatic perceptual nature.
- 04
A carpentered-world hypothesis proposed by Segall, Campbell, and Herskovits suggests susceptibility to the Müller-Lyer illusion stems from growing up in environments full of rectangular structures.
