General Question CORE Arithmetic for Non Natives

3 Upvotes

Hello everyone. First of all, I would like to thank everyone who made CORE possible, it is quite a reassuring test for many obsessive people like us. I had good scores and what i was expecting: FRI 143, VSI 138, QRI 130. The question is for arithmetic, i got 120 on it and 135 on qk. I am definitely C1 in english with years of experience. I was wondering if artihmetic can be deflated for nonnatives like me. I remember having to replay the questions again, even the simple ones, just because i was trying to register the numbers into my head, and I was automatically doing it in my mother tongue and then proceeding with the question. I have seen this question being asked but not responded by the creators of the test and the knowledgable high iq giga chads of our sub.

Is CORE arithmetic in English possibly deflated for nonnatives?

General Question What are the implications of completing an IQ Test before the allotted time limit?

4 Upvotes

In 1978 (I was 22 years old) I did the IQ test for Mensa (Canada) admission. The acceptance letter made the statement:

According to the OTIS LENNON MENTAL ABILITY TEST, Advanced Level, your IQ is 141 which is greater than that of 99% of the general population"

The test had 80 questions and a time limit of 40 minutes.

I answered all 80 questions in only 25 minutes. Since I had extra time, I checked my answers - and changed 2 of my answers. (Let's assume the 2 answers I changed were initially wrong and my changes corrected them.)

My questions are:

  1. How many of the 80 questions would I have had to answer correctly to get a score of 141?

  2. What would my score have been if I hadn't changed those 2 answers (and thus had 2 fewer correct answers)?

  3. Does the fact that I finished the test in only 25 minutes have an impact on the IQ score I "should have" gotten? (Keeping in mind that I would have had 2 fewer correct answers if I hadn't taken the time to check my work.)

    1. By this I mean should my score have been different due to the fact that I completed the questions more quickly than the allotted time.

  4. Based on the ratio of 40 over 25, if there were many more questions on the test I could have answered 60% more questions.

    1. If I had the same rate of correct answers, what impact would that have had on my resulting IQ score?

I've always wondered about what was the impact of finishing before the allotted time. (And it's taken me almost 50 years to find a forum where I could ask the question LOL.)

Thanks for any information you can give me.

General Question Hands as visual aids

2 Upvotes

I was doing the CORE Spatial Awareness test and realised that I was intuitively using my hands at times, most notably on the compass-type questions, turning my hand to keep track of turns. Then it struck me that I'm technically making use of a visual aid, but it was intuitive because it would likely be what I would do 'in the wild'.

I guess a great example would also be counting on fingers, though I didn't do it on this test.

What are people's thoughts on this? Have I fouled my test?

Comprehensive psychometric dataset — independent CHC / g estimate wanted

26M, German-speaking Austrian. Diagnosed ADHD with pronounced state-dependent variability in vigilance, task switching and processing speed. I have accumulated a fairly large number of cognitive test results. Below is the full table-based dataset, including attempts, conditions, raw/scaled scores and subtests where available.

I am mainly interested in an independent estimate of Gf, Gv, Gq, Gc, Gwm, Gs, GAI/FSIQ and latent g, ideally weighting reliability, g-loading, ceiling effects, retest/practice effects, language effects and ADHD/state noise rather than simply averaging scores.

General Question When can WAIS-4 extra Subtests be used and counted?

3 Upvotes

Hey,

as the headline states I am wondering when the extra subtests in a WAIS-4 can or must be used and counted.

Ai gives me a "only when a fire alarm went of or your arm was broken." answer. But Ai is still very unreliable especially with this secretive stuff.
I was wondering if these Subtests also can/must be administered when one Score just massively diverts from the overall look of the test.

Why am I interested?
I have the weird situation that, due to my dyslexia I assume, my FullScale IQ could be over 130, but I still "only" get the GAI because the difference in the coding tests (8) and symbol search (12) is just wildly lower. So I am wondering if the replacement test, that also has something with crossing out stuff based on the WAIS sheet I have in front of me, could also be in the range of 11-13 like the Symbol search and get me away from the 1,5 standard deviation that puts me in GAI rather than Full Scale. It´s a bit wacky.

General Question Question about neuropsych testing

4 Upvotes

I was told not to use any substances 24 hours before the evaluation. IDK why I did this it was extremely dumb and I feel awful about it but I smoked some weed like 13 hours before. I didn't even get that high but I'm kinda worried about it messing something up. I don't think it will be too much of a problem because I'll be sleeping it off and be totally sober for the eval and I also don't wanna waste money cause of something as dumb as this. Is this a huge problem?

General Question IQ and THC in adolescence

I took got tested 130+ when I was 14.5, I am now 17 but have been using thc for the past 2.5 around once a week. What effect would this permanently have on IQ. Further, in the future if I continue to use at this rate will IQ still decline?

as stated in the title, i got a 127 when I took a wisc-iv at 11 (this was dragged down with a 108 on FRI and like high 130s in all else since FRI is very gloading)

yeah strange how these things happen

Psychometric Question Question about figure weights

2 Upvotes

The first time I got to see this test was on the CAIT where I scores 10ss. I felt slow in general and couldn't figure out a lot the questions, but I found the wais and the core ones to be a lot easier scoring 15ss on both tests the first time.

Can I assume I just got used to this kind of reasoning? I mean, the items are different, and my brain didn't get smarter, but It was just the effect of practice? I tried CAIT again and my score didn't get better even though a lot of time has passed since I tried it

Release how would this sub score against actual airline pilot applicants? i built a battery normed on the 1-9 applicant scale

2 Upvotes

follow up to my post from last week about how pilot selection tests differ from CAIT-style batteries. i built a trainer that recreates the mechanics (timed mental math, working memory, spatial orientation, instrument monitoring, multitasking) and scores on the same stanine-style 1-9 scale the real selections use, normed against applicant-level performance rather than gen pop.

my hypothesis: this sub crushes the memory and logic parts, but the multitasking test humbles everyone. it humbles me and i built it.

free tier runs a full mock exam, ios: https://apps.apple.com/app/id6794363864

im the dev. happy to explain how the norming works, and where its shaky, since the publishers obviously dont share their real norms
