There is nothing special about algebra in that regard. Ask blind person to recall some visual memory (from before they went blind, obviously) and the effect is exactly the same. Or ask any healthy person to close one's eyes and do algebra - still the same effect.
The point is: our brain does not really tells apart reality from imagination. The same areas are involved in processing real images comming from the eyes, as well as internally "rendered" imaginary images.
- panglott 10y agoThe study examined people blind since birth. But the article doesn't say much about the degree of their visual impairment—there's a big difference even between "no light perception" and "light perception only" (where people can still get visual information useful for orientation), much less higher amounts of vision. If the study was restricted to people with no light perception since birth, that's a very small population, getting a larger sample might be difficult.
