Completely missed this thread.

I've been through the last five or six years of the Eides blog at:

I'm not familiar with the WJ-III. With a quick read of that test description, they are talking about a long term data retrieval for their visual auditory learning test. It looks to be using picture sequences and word queues and testing recall.

The problem is people have fixated on Howard Gardner's notion of multiple intelligences and responded to that in thinking that people specialized in an area would do better with material presented in a certain style. For example: If you test high on visual preference, then you should be presented materials to learn through a visual medium... that isn't necessarily true.

To contemplate the difference between the literal sense and a mode of thinking characterized by that sense, think about what is meant by each of these phrases:
"That sounds right."
"Do you see what I mean?"
"Something smells odd about the situation."
"This doesn't feel right."

There are compounding factors behind dyslexia and ASD over and above the brain organization. i.e. the minicolumn structures may be a necessary factor, but are an insufficient factor in those conditions.

With the caveats above, I'd characterize myself as an extreme visual spatial thinker. I have to have a top level perspective to understand facts and those need to fit within that larger structure to make sense. At the other end people seem to populate from details and build upwards. I doodle constantly during meetings or on the phone. I can't remember the words to songs, actor's names, etc. I also don't have depth perception, except in my head where I can design anything in 3D.

I'm at an extreme, and I'm not dyslexic. But I solidly match all of the VS characteristics here: http://www.gifteddevelopment.com/Visual_Spatial_Learner/vsl.htm
However I don't think in pictures.

Diagnostic criteria take a pretty high hit rate to become true. There isn't exactly a sliding scale on enumerating characteristics. A gifted introvert could be armchair self-diagnosed as being on the autism spectrum.
