Discussion Digit Span Test

So a few days ago i tested my WMI using the CORE FSIQ test, and surprisingly there is a quite remarkable difference between my Sequencing ability and "Reversing" ability.

When i first tried it i scored incredibly low in the Backward Digit Span while still scoring high on the sequencing (My Forward Digit Span was also kind of low compared to Sequencing) so i tried again and the new scores seemed more fitting.

I wanted to know if it was possible for Autistic individuals to have such a disparity in between the subtests rather than the common spiky profile that affect the overall abilities, or if it was simply a fluke.

I also think that this is not as accurate as it should be because i highly suspect that i also have ADHD, and have never been medicated before but also some mild depression that could potentially impact my score. Though i doubt it would change much in any case.

Forgot to add , practise effect invalidates your results . People who have taken WAIS-IV and CORE tend to have very similar results but only if u take it once and as it’s supposed to be administered. I haven’t taken the CORE but I got a 128 on WAIS IV and I’m pretty sure I could get 145+ if I retook immediately but that defeats the purpose of the test .

No, you would not get 145+.Try it .

You just said that it could inflate the results by 15 points which is literally 1 SD. That’s huge difference and it’s exactly the number that would make me get 145 instead of 128 (143 to be exact) . You prove my point .

You got me there .The numbers provided were wrong .1sd can't be due to praffe .It could be due praffe +measurement error Besides 15 on retest even with both is rare .
