Aging, Dyslexia and Neuropscyhological/Memory Testing

In my CAP testin of children with the Random Gap Detection Test, those children who have failed to detect 2 sounds at the 40 millisecond interval have often reported they only hear 2 sounds on the Duration Pattern Sequence and the Pitch Pattern Sequence test for auditory memory. (which is why I don't use those tests anymore if the RGDT is positive)
Since you can't remember what you didn't hear, the test results would therefore indicate an auditory memory problem when in fact it was a perceptual problem related to temporal processing.
Recent information has indicated that temporal processing among Dyslexics becomes worse with advancing age.
Question:  How much of any abnormal result regarding memory is a result of auditory temporal processing disorder and CAP disorders resulting from those with dyslexia and/or sensory deprivation (which will also slow auditory temporal processing).  After all a 7 year old dyslexic will be a 70 year old dyslexic and there are quite a few out there.  Is the presentation speed of verbal material taken into consideration or it is a professional bias thinking that slowing down verbal speed relates to cognitive dysfunction rather than perceptual deficiencies?
