VIQ>PIQ?

Post Reply New Topic

For those of you that have had a formal IQ test like the WAIS only:

Have you been diagnosed with AS?

Is your verbal IQ 10 or more points higher than your performance IQ?

I am writing a paper comparing and contrasting AS and NVLD and I am finding very contradictory results as to whether people with AS and those with NVLD are similar in terms of their cognitive strengths and weaknesses or not.
I was curious about WP population =)

Diagnosed, but not properly tested for PIQ/ VIQ. I have done a verbal IQ test before and it was average but it's developed since. My performance, however, is probably less than average. It's not really an official result but more an opinion of myself.

My VIQ and PIQ score very even. My processing and working memory differing from the PIQ and VIQ is where the gap is.

diagnosed aspie and PIQ > VIQ

according to the WAIS III:

PIQ = 99.8 percentile
VIQ = 85 percentile

i have a PIQ > VIQ gap of appr 30 IQ points or two SD's (standard deviations)

I put "suspected":

VIQ higher than PIQ by 35 points.

Subtest scores ranged from 5 to 18 (in whatever scaling that is).

I can't recall the exact percentage off the top of my head but my verbal IQ is in the superior range and my performance IQ is in the average range. Also my verbal memory was in the top 95% of people while my visual memory was just average which I was surprised about as I thought my visual memory was quite good apparently it's relatively unusual to have that kind of discrepancy in memory and it's common in aspergers. I don't know if anyone else found that?

Same for me, I had a 40 point difference betweein VIQ and PIQ when I was about 14. It has decrease to a 12 point difference the last time I took it a couple of years ago. Annoying, isn't it. It is like knowing all the big answers, but not knowing how to do anything with it.

Sluice!

Thats EXACTLY what it is... I call it being able to talk the talk but not walk the walk!

I'm highly vocal and can shoot my mouth off about topics but if I was put in a practical situation and had to apply my so called knowledge I'd be like, errr... And then probably give up!

The most bizarre thing of all is that it doesn't only reflect in WAIS testing you can see it in my Uni grades too, I find that in exams and essays, more often than not I can get A grades but my project grades are usually lower ranging all the way from As to Es depending on the type of work.

Its really annoying especially as sometimes people can mistake being good at written work for being a genius but then when they get to know me they realise soon enough that I'm not!

I've taken seven WAIS tests in my life and the discrepancy between VIQ and PIQ has always been at least 19 points. The largest gap between my scores was obtained on the most recent WAIS I took in June. My POI was 79 (borderline range) and my VCI was 136 (superior range.) That's a discrepancy of 57 points and only a tiny fraction of the population exhibits such large gaps between VIQ/VCI and PIQ/POI. It doesn't seem THAT unusual for those with AS/NVLD though. There is a poster in this group who claimed their PIQ tested in the 60's (MR range) while their VIQ was in the 160's (very superior/genius range.)

I can understand why VIQ scores can fluctuate from test-to-test, but my PIQ scores have also fluctuated greatly and i'm not entirely sure why. For instance.....my PIQ on the WAIS I took four years ago was 111 (while my VIQ was 155 on the same test....these scores yielded an FSIQ of 143) and that's in the high average range. My POI/PIQ on the most recent test was in the borderline range at 79. I can understand SOME variation in scores due to mood, tiredness, etc.....

But a 32 point discrepancy between my PIQ/POI scores in 2006 and 2010 seems quite odd. Nonetheless, I scored in the borderline range on PIQ when I was 23 and until recently, my PIQ scores have been in the average range and high average on the test in 2006.

I think alot of it has to do with processing speed. For one example.....the block design subtest on WAIS is a timed test and therefore very dependent on processing speed, particularily when it comes to visual processing of course. My processing speed scores are usually on the low side and they were also borderline on the latest test. I did score 108 on processing speed on a WAIS I had in 2001 and my PIQ score on that one was 102.

So if my PIQ score largely depends on processing speed (though i'm not sure of this either) i'm wondering what factors determine processing speed from test-to-test.

I think it is probably anxiety or mood or tiredness or even time of day that affects the PIQ. I'd guess that my PIQ would be lower in the morning than in the evenings as I'm so groggy in the mornings, plus the more caffeine I'd drink the more focused I'd be on what I was trying to do. It would always be lower though as I find the tests for VIQ kinda stupidly easy so I guess VIQ would always be superior! I'm not convinced it's s great way of testing intelligence, it's just testing verbal memory really I reckon?

Thanks for your replies everybody.\


I am thinking that NLD and AS are not the same thing ....a lot of aspies seem to have VIQ =<PIQ....and some have exceptional spatial-visual abilities. However there was some research showing that people with AS DID have more visual-spatial difficulties than the rest of the population. How to account for those findings? I think NLD may occur more in people with AS than in the rest of the pop bcs the two disorders have similar etiology i.e. both are thought to be caused by right hemisphere dysfunction and white matter abnormalities. Does anyone have any thoughts about this? Does anybody know this to be UNTRUE? If so please let me know

I apologise for any bad spelling/grammar.....it is late at night. or more accurately early in the morning (here in Canada anyways)...and I am very very tired.

My PIQ is higher than my VIQ. I was diagnosed PDD-NOS at the age of 5 and Aspergers more recently. But if you want to go with the paradigm that AS and HFA are different I'm probably closer to HFA, though it's a mild case in either case.
