[edit] Muller-lyer illusion article

The following quote is from the duplicate article:

"A Muller-Lyer Illusion is an illusion consisting of two lines in which one of these lines has an arrow turning toward the periphery, while the other has lines turning toward the center. This illusion can be explained by the Perspective Constancy theory, which states that certain stimuli features, like the arrowheadsof the figure, are indicators of apparent distance, thus providing false cues. As a result, size constancy is inappropriately induced to compensate for apparent distance of the two parallel line segments."

[edit] Judd Illusion

There seems to be confusion in this article in the relationship between the Müller-Lyer illusion and the Judd illusion. I recommend creating a new article for the Judd illusion and making the relevant changes here. The Judd illusion seems to be when the arrow heads are pointing in the same direction (on a single line):
