Welcome to Wrong Planet again.
Monotropism - A tendency to focus attention on one thing at a time, with difficulty shifting attention and processing multiple stimuli which might support understanding.
I would say that I have that trait also. The reason why it takes a bit longer to understand things is because
Most NTs look at things from only one direction, whereas many Aspies will evaluate something from several different directions. As a result it just takes us a little longer to reach a position.
In a normal conversation with NT, they begin a topic and talk about it for a few seconds and then move onto another topic and then another. Meanwhile I am exploring the topic and I finally provide my thoughts and inputs. But by that time they have gone through several topics and are far away from the original topic. As a result I am out of place. So it doesn't make any sense to them because they are no longer in that topic area anymore.
