I have fairly significant working memory issues, particularly with complex working memory. I didn’t realize it until I was diagnosed (the diagnosis included the Wechsler Memory Scale - WMS-IV).
So, I am still trying to piece together how this disorder all "fits together" (as a system).
It seems like there are a number of core cognitive weaknesses (including, but not limited to, Complex Sensory, Complex Motor, Complex Memory, Concept Formation, Face Recognition) that manifest themselves in a set of behavioral symptoms that is describe as Aspergers.
There are at least three cognitive theories of ASD -- including Theory of Mind (ToM; Baron-Cohen, 1989), Theory of Executive Dysfunction (Ozonoff, Pennington, & Rogers, 1991), Weak Central Coherence Theory (WCC; Frith & Happé, 1994; Happé, 1999). You can google to find the papers.
