This reads to me like pseudoscience. "The process of compression happens because the brain is a highly complex organ with many things to control, and it can focus on only a few uncompressed ideas at one time." Yet it comes, apparently, from Jo Boaler, a Professor of Mathematics Education at Stanford University. Maggie Hos-McGrane expands on the thoeory: "The brain can only compress concepts and not rules - hence students who learn the rules have to struggle to hold onto them - they are unable to be compressed, organized and filed away for later use." This doesn't make sense to me. The brain is not a computer. I'm open to the possibility that I'm wrong here, but I really doubt it.
