I know that blind people can imagine rotation in the mind akin to sighted people. You can feel an object with your hands just the same as it can be seen.Maia wrote: ↑Wed Jun 14, 2023 10:26 am+++The most obvious ones are with imagined physical rotation of objects.

+++Key findings
Tests developed for sighted individuals are not always appropriate to use with blind and partially sighted people.
Non-verbal reasoning tests are more problematic than verbal reasoning tests as they often use pictures and images which are inaccessible to blind and partially sighted people.
Psychometric tests are often used to test innate ability, but the skills being assessed for a blind or partially sighted person may differ from the skills being assessed for a sighted person.+++
Perhaps surprisingly, there is still no universally accepted IQ test to measure the intelligence of blind people, though there have been a number of partial proposals.
So, with regard to being able to imagine the physical rotation of objects in one's mind, this is something I do all the time, without thinking about it. I couldn't navigate the world if I didn't. I don't do it visually, though, and this is what standard IQ tests measure. Perhaps the same is true of a lot of other people, too.
The point is about the ability to Abstract experience. It requires memorization, imagination, and then imagined manipulation.
Blind people can understand mathematics too. So IQ tests can be applied to them within the mathematical parameters. Nobody can rule-out validity of IQ tests without ruling-out both mathematical and verbal understanding, which is mostly innate and ingrained, because of how humans learn about the world and society during the infantile stages. Even a feral child understands the difference between 'one' and 'many', for example. But feral children likely do not understand 'zero', because that requires Education and Abstraction based upon that education.
