> So if I spot it then what does it tell me about the spectrum Probably nothing - except that you don't see a box in perspective, looking at the diagram below, the "shape" synthesis in your brain might be different. Your mind isn't taking the "box" below as a 3-d box in perspective automatically, which is what a filtered perception should have (just enough detail to be useful, not enough to overwhelm you). If you, like me - see a square and two parallelograms instead, it becomes trivial to ignore the colours guiding your eyes on the top image. Yellow square ... yeah. Red blue parallelogram to the top right of it, yeah ... Whether you perceive reality as a mixture of abstract shapes or whether your brain smoothes over it to form meaningful structures (like a box) is relevant to autism (one assumes). Reassembling fragments of perception is a very well exercised part of my brain, because it is necessary for me to operate - but beyond that, it gets easier to reshuffle them before reassembling, which is what this is test is about. It is a test of being "mentally bilingual - reality and perception", which is necessary to overcome being somewhere on the spectrum and be functional.
