I think what you're wondering about from a slightly different angle is - was your ds" relatively low score Picture Concepts score related to his other relatively low scores (I think he h ad dips n processing speed or maybe wm?) or was it just related to how he performed on that one subtest. I know it's been a long time since he was tested, but was,there anything about the s in the report or in your interview with whoever did the testing at the time?
I would be interested in hearing if there is something that might connect a low score on Picture Concepts with low scores on PSI subtests because my dysgraphic ds also had a relatively low score on Picture Concepts.
And on a slightly unrelated tangent - my kid saw a typewriter for the first time last summer.... Ina museum!
