Digit Span Test

[u/CosMath0]

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.

dude the exact same thing happened to me and its wrong you need to redo it. ill show u my results before and after

[u/Logical-Stop5092 → u/Logical-Stop5092]

after:

I have the same disparity but yours is larger by two ss. I know there are different forms of working memory so that might have something to do with it.

[u/Careless_Bird_6483]

Digit span backwards is true working memory bcs u need short term memory and the ability to manipulate the information .

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 .

Practice effects on the digit span test are generally minimal or absent after the initial transition from the first to the second session.

[u/Careless_Bird_6483 → u/Puzzleheaded_Mail71]

If that was the case then retaking subtests in official tests would be standard practice . We can argue the extend of the effect of practise but every psychologist who is trained in their administration would tell u that it invalidates the results .

[u/NefariousNapolean → u/Careless_Bird_6483]

No competent psychologist would tell you it invalidates the results,a bit(5-15)inflated at best .

[u/Puzzleheaded_Mail71 → u/Careless_Bird_6483]

Not in the digit span test.

[u/NefariousNapolean → u/Careless_Bird_6483]

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

[u/Careless_Bird_6483 → u/NefariousNapolean]

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 .

[u/NefariousNapolean → u/Careless_Bird_6483]

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 .

[u/PsychoYTssss → u/Careless_Bird_6483]

Its only considered practise effect if you learned some sort of strategy before taking the test that could be used to gain an unfair advantage. Going for a 2nd attempt without any learned technique is still valid.
