There is hardly an autistic behaviour that cannot be seen in NTs. As I said, that does not mean it is not an aspie behaviour when performed by aspies.
The reasons why NTs cannot read maps could be completely different.
You could be onto something.
I have to piece together landmarks and features to work out where I am. So there is a church over there, a bridge here, a wood there and I should be at that junction in the path. I have to piece the clues together.
Some of the NT scouts I used to lead who could read a map could look at it intuitively as a whole.
Thank heavens for GPS. They make life so much easier.
Doing analysis of maps and satellite images- that is a whole different pass time. I love doing that.
