Is there a better example of this somewhere? It seems obvious to me that the effect behind the "green US flag" optical illusion could easily explain this example.
If you look at a white surface after staring at the top pair for 30 seconds, you will perceive a black left-side circle with a few white dots and a black right-side circle with many white dots. If, instead, you look at the bottom pair (as in the example), the perceived black right-side circle's many white dots compete with the pictured white right-side circle's black dots, thus decreasing your perception of their numerosity; whereas, on the left side, there is no visual overlap between the perceived black left-side circle's few white dots and the pictured white left-side circle's black dots.
The difference in perceived numerosity between the two sides can therefore be explained by the fact that on the bottom left, you see all the black dots without competition, while on the bottom right, you can't see all the black dots at once due to competition from overlapping perceived white dots.
I could be wrong, and if someone can find a counterexample where this is shown to be a poor explanation, I think the article would be improved. If I'm right, I hope that not too many false conclusions have been drawn from believing in this "adaptation effect." —Preceding unsigned comment added by 67.194.75.35 ( talk) 18:45, 12 May 2011 (UTC)
