My eg/pg son (now 6.5) has had 2.5 years of vision therapy. He just finished over the holidays. He was born with muscular torticollis, hypotonia (low muscle tone, and visual processing/perceptual deficits; he's had tons of therapy. Apparently, it's common for children born with ocular tort to have strabismus so I've heard of them having surgery and/or vision therapy as well, though most have sought surgery.
My son was barely scribbling at 4 yrs old before vt started; yet he knew all his shapes, letters, and numbers and had had 4 yrs of pt/ot to encourage writing. About 6-8 months after starting vision therapy, we started to get a lot of writing. Then it was a flood and has continued on and off. He's now 6.5 and writing sentences, paragraphs, stories, e-mails, and on and on - way above other late kindergarteners.
As for reading, my ds was 'reading' before vt but not out loud or really reading. After 1 1/2 of vt, he started to read out loud. Last summer, he was struggling with phonics. Today, he's reading many, many grade levels ahead.
I've never heard of Digit Span - but this sums up a lot of situation with my ds. It also coincides with him being a visual spatial learner.
My DS had the WPSSI last summer when he was in VT and wearing glasses. Scores came back too scattered and inconsistent. I wanted to scream.
In Feb, DS took the Woodcock Johnson Achievement Test through the public schools. He did better, but still wasn't totally cooperative. He told the tester that since he's in kindergarten, he's only going to do kindergarten math - despite the fact that he was able to do more and multiply.
I'm in the process of seeing a 2e specialist. I think DS's hypotonia, sensory, and visual issues have had an affect on his attention span and testing scores. I'm waiting to get a more definitive answer though.
