I believe this is slow processing speed. When I had my son tested, he was in the lower percentiles for processing speed and I immediately remembered scoring low on processing speed in a test I had taken 25 years ago.
A previous poster said she “sees the forest not the trees” which is is a great description and a great blessing. Yes, I need to understand the whole system to understand any individual part but that has made me very successful. Being able to see the forest pays much better than seeing trees;)
As for my son, he’s slow to pick up on new multi-step instructions but his fluid logic scores are off the charts. We both excel at anything that includes a large, complex systems (computers, accounting, home theater setups, networking, etc).
