What I do find associated with lower FR is the rigidity, quirkiness, sensitivities, and sometimes challenging behavior that you are reporting; this may be conceptualized in the context of nonverbal learning disabilities.
My apologies to the OP if this sidetracks, but a question to aeh. I always got the impression that NVLD was associated with weaknesses in the VS part of the old Perceptual Reasoning measure in the WISC-IV, as opposed to the fluid reasoning measures (but descriptions did tend to be fuzzy). Does NVLD still associate the same way with low FRI now that visual-spatial has been moved to a separate measure?
