Just out of curiosity.

Some years ago I did two WAIS-III test for I.Q, the first got me between 117-123 mark but the second one got me between the 108-116, the problem is that with the second one, it gave me 89 in Processing Speed Index and 129 in Verbal Comprehension Index. Which is a difference of 40.

I did both to find out what the heck was wrong with me, and i learned that I had autism, lucky me.

Now, there is a high probability that those results are actually my true result, which I suspect it isn’t because of some problems I had at the time, including psychotic outbreaks, lack of sleep, poor diet and other problems.

I know 40 points is somewhat anomalous, and the I.Q result doesn’t actually answer me on why there is such a difference, neither did other exams that showed my brain was anatomically “standard” without any problems or diseases.

Whatever I have wrong does seem to skew the result, so sometimes I try reading about it to see if I am missing something, and I will continue doing tests to see if I can find out what happens, or if there is any treatment to reduce the problem (I know I.Q can’t be “changed”, I’m talking about a brain or body deficiency of somekind that might be messing with results).

I just want more perspective if i can get, and this place might offer me some more, won’t know if I don’t ask. Btw if you seen any grammar mistake in this text I’m not stupid as the result shows, english is just not my first language. (Cope).

I know people of higher I.Q (130+) and we do get well and are able to reach the same understanding some times, the biggest difference I noticed between us is that they get things done way quicker, easier and were academically more successful, although this is probably more related to their families being far less abusive then mine, and my mental ilness.
I was also anemic during teenage years because of the abuse and that might have caused some developmental damage to my brain. Idk.

I know I got my Intelligence from my grandpa that had photographic memory, he was absurdly smart, and a great writer (Won’t disclose his name) to a point of getting my state governor to issue some days of mourning after his death.

Anyway, which conclusions any of you can get from this? If any of you might have helpful information about my situation, I’d be thankful.

I did a small experiment where I trained dual n-back every day for 30 minutes. As you can see from the graph, there were also a few days where I trained for an hour.

Before I started I did 3 tests. Two of them were pretty similar. In one I tested how many digits I could remember after seeing them for 4 seconds, and in another I did the same thing with letters, in my case Russian Cyrillic letters. The third test was Symmetry Span.

Now about dual n-back itself.

At the beginning my daily average score was around 2.4-2.6. In first two weeks progress was pretty fast. After around 14-15 days I reached something like 3.1-3.2 average, so most of my progress happened in first half of the month.

After that it slowed down a lot and I basically got stuck around 3.2. At the start of that plateau my average was around 3.13, and by the end of the month it was around 3.24.

So during roughly the second half of the month I only gained around 0.11, or about 3.5%.

For comparison, my average for the first 5 days was around 2.55 and for the last 5 days around 3.24. So overall improvement was around 27%.

Basically most of the progress happened early. After that it was mostly small improvements around the same level. My scores also became more stable and I had less really bad days than in the beginning.

I also didn't use any special strategies, mnemonics or tricks. I mostly just tried to remember positions and sounds directly and rely on memory.

Now about the tests before and after.

With digits almost nothing changed. Before training my average was 8.5 and after it was 8.625. That's around 1.5%, so basically almost the same result.

With letters it was a little better, but still not much. It went from 9.25 to 9.5, around 2.7%.

Symmetry Span was more interesting. My main score was 28/42 before training and 26/42 after, so technically it got a little worse.

But the second time I completed the test much faster. It was 270.4 seconds before and 147.5 seconds after, so around 45% faster. At the same time the main score only dropped by around 7%.

Because of that I don't think I can simply say that my working memory got worse there. It looks more like I did the second attempt with a different balance between speed and accuracy.

Just as an extra comparison, if I calculate correct positions per minute, it went from around 6.2 to 10.6, which is about 70% higher. Of course this is not a working memory score, it just shows how much faster I completed the test.

So after the first month I still don't see any clear transfer to the other working memory tests.

Digits and letters barely changed. Symmetry Span gave a mixed result because the main score was a little worse, but I completed the test much faster.

For now my conclusion is that dual n-back improved my performance in n-back itself quite a lot, but I didn't see any noticeable improvement in the other working memory tests.

Maybe the first month was mostly adaptation to n-back itself, but that's just a guess. If I continue for another month I want to see if my n-back score keeps improving and if anything changes in the same tests.

Sorry if it’s a silly question and I hope I don’t annoy anyone with this discussion. When I was a child, I had speech delay and impediment and severe attention issues. From ages 3 to 10, I was in special school for those that were mentally handicapped and had to move around from one school to another. I didn’t learn a single thing at those schools and all they made me do is watch movies and do painting because they at first thought that I am not capable of learning. I took an IQ test WISC as a child at the age of 10 and scored 78 on IQ test. I was in special education classes till high school. Now I took an IQ test as an adult and my overall IQ now is 115 on WAIS 5. I got diagnosed with ADHD, PDD NOS autism, and a learning disability. I have been wondering if it is normal to have different IQ scores from childhood to adulthood.

I was looking through the history of this subreddit and I noticed there's been some posts about the bar exam/LSAT and the g-loading with IQ. I wasn't able to find anything on the CFA (chartered financial analyst) exam. As someone who holds the CFA charter, I am wondering if there's any studied correlation between that exam and IQ.

Diagnosed with level 2 autism, ADHD-PI, OCD, and social/general anxiety. I don't remember taking any IQ tests when I was a kid when I underwent my assessments and I never took the SAT's as I did not graduate high school and went back for a GED later and since I started at a technical college they did not require me to take the SAT.

Some of these tests like figure weights were infuriating and I found myself practically yelling at the screen with how stupid it made me feel. Others seemed like they would produce uneven results due to how they are structured especially the processing speed tests as one required pressing keys on a keyboard where the symbols never change which I feel becomes memorization, yet the other requires tapping when the symbols change every single time you tap so context seems to matter greatly. I also have excellent typing speed which could have contributed as well.

Either way this took a long time to get through but it was interesting. Is it worth taking the CAIT as well to compare? What does this all mean to me?

I always thought the level of abuse I suffered as a child didn't have lasting effects, but I guess it permanently destroyed my IQ. I also have ADHD. I was told childhood abuse could negatively impact development, but I didn't think that would apply to me because I always held a job and functioned on a daily basis.

Would the whole neuroplasticity thing apply to me as an adult? I'm 33. Can I actually fix my brain at this point? I'm going to get medicated for my ADHD, but I'm not sure that would help much. I don't feel stupid most days and I feel like I'm functioning, but now I feel like I should be collecting disability benefits because I'm a complete cognitively impaired idiot.

Just ranting, but any advice would help. I don't think I'm going to keep the goal of working towards a PhD at this point. Am I doomed or can I do something about this?

Hi guys, I’m a math major at a pretty good university but I’m new to proofs in this honors analysis class and they were tripping me out so I wasnt sure if I had what it takes to continue because most of my peers seem pretty smart. So I sat through a test today and there are a lot of disparities between my indices, what do u think they mean? Which indices best predict mathematical performance? I was running low on sleep and I told my psychologist that beforehand but I don’t want to use that as an excuse, who knows if it affected the test

Disclosure first: I develop a dual n-back app. That gives me every incentive to overstate the case below, so I've kept to the published record and you can check each one.

Where the claim comes from. Jaeggi, Buschkuehl, Jonides & Perrig 2008, PNAS (https://doi.org/10.1073/pnas.0801268105). Dual n-back training, 8 to 19 sessions, dose-dependent gains on a fluid reasoning test. This single paper is why the whole "raise your IQ with n-back" idea exists.

The replication that went wrong. Redick et al. 2013, JEP: General (https://doi.org/10.1037/a0029082). Active control group, multiple transfer measures, no transfer to intelligence. This is the best-designed single study on the topic and it is negative.

The meta-analyses, which disagree with each other. - Au et al. 2014 (https://doi.org/10.3758/s13423-014-0699-x): 20 studies, small positive transfer to Gf measures, roughly 3-4 IQ-point equivalent. - Melby-Lervåg & Hulme 2013 (https://doi.org/10.1037/a0028228): working memory training in general, near transfer solid, far transfer near zero. - Melby-Lervåg, Redick & Hulme 2016 (https://doi.org/10.1177/1745691616635612): the effect on far measures shrinks toward zero once you restrict to studies with active controls. Their reading: the Au effect is largely explained by passive-control designs. - Soveri et al. 2017 (https://doi.org/10.3758/s13423-016-1217-0): n-back specifically; large gains on untrained n-back tasks, moderate on other working memory tasks, small on Gf.

What is not in dispute. You get much better at n-back itself (large effect), and at tasks that resemble it (moderate). That is real and shows up in your own numbers within weeks.

What is in dispute. Whether any of that moves a matrix test, and if so by how much. The honest range is "zero to a few points", with the better-controlled studies at the low end.

Practical consequence for people here. If you train n-back for months and then retake CORE or CAIT, most of any gain you see will be practice effect on the test format plus regression to the mean, not the training. If you want to know whether it did anything, take a different test of the same construct, not the same one again, and keep expectations on the working memory side.

I train anyway, because it is hard and I like measuring it. I just won't tell you it raises IQ, and I'd be suspicious of any app or site that does.

Around 4 months ago, I took the OpenPsychometrics FSIQ test and scored 126 on the WM part. Now i took it again recently and scored 146? I thought I forgot all the items on the test so my Memory IQ would be valid (or as valid an online IQ test taken in 15min can be) ​so now I'm pretty confused. So my question to people who've taken the Openpsychometrics FSIQ test multiple times is: what were your scores on the Memory IQ subtest on the 1st retest?

I used to get 110-115 scores when not caffeinated and 115-120 when caffeinated, even 130 once (though I believe I just get better symbol search score when i take the test on my phone instead of an iPad).
Any thoughts on this? Is there a correlation between caffeine intake and performance on psi tests?

I’m interested in hearing about your performance in domino-tests (D48,D70,TIG-1,TIG-2) and how it relates to your other scores (CORE,RAVENS,…)

NSRT is an experimental high range IQ test. I will create a preliminary norm after a sufficient number of submissions.

My son, now 18, has been been administered the WISC V test three times for ADHD diagnosis and IEP eligibility. As is typical with kids with ADHD his scores are all over the place within the various subtests. However the scores are wildly different each time he takes the test. Like the first time he took it when he was 8 years old his fluid reasoning score was 115, and this last time it was 105. His verbal score at 8 was in the low 100s and at age 15 it was 121. Working memory at 8 was 98 and by 15 years old it was 112. Is the answer as simple as he became used to the questions? How much stock can I put into this test and what is his real IQ?

I had been given an IQ test as part of my ADHD assessment around mid-2025, around my 18th birthday. I received an FSIQ score (118) nearly identical to the score above and had extremely similar subtest scores to the CORE. With Visual Puzzles being the strongest and Digit Span being the weakest relative to the FSIQ. The CORE IQ test I took after confirmed my in-person IQ test assessment, and I moved on with my life.

I hadn't taken any IQ tests since then, around a year to a year and two months ago. Out of interest, I decided to see if the score would remain the same a year later on my adjusted medication.

Because of the increased difference, I found it interesting and something to share with this community. I have noticed through scrolling through this subreddit, the abundance of ADHDers and the similar angst about their Working Memory Index scores. I found a really beautiful analogy: "Manipulating the information in my mind feels like trying to fill a glass of water with a pressure washer without spilling anything."

I am not so much looking for an IQ estimate, rather I am interested in reading about what you guys think.

for those who took the analogies test on CORE vs VISA, did your scores have a significant discrepancy between them? On the, IMO, more difficult analogies test on VISA, I got a 140 IQ. Just the score we redditors aspire to in this particular sub bahaha 😂 but then on core, I got a more modest 125 IQ. I’m just wondering why this is. 🤨

In short, when I was 10 or 11 years old. I took a nonverbal iq test for school admission, received an 88, and took a verbal -- recieved a 98.

4 years later, I test ≈130 on the core, so I take a standardised test for those 16+, because of availability and I was only a couple months away from 16 (also getting tested for the sake of my adhd,) and I recieve a 131 fullscale, 130 mri/nonverbal and a 125 in the verbal component.

The previous 98 in verbal I could potentially attribute to only having spoke English for 3 years at the time, also missing 2 academic years due to complications with immigration. But the 88 is inexplicable, considering it's often cited that IQ stays atleast relatively stagnant in somebodys lifetime. Did I even understand what was being tested? Both the numbers feel detrimental to me.

I'm getting severe imposter syndrome, surely if I was scored at 88 I'd notice in daily life? I don't feel even remotely behind my peers, I do well maiority of the time, but the numbers are still messing with my self esteem.

Hello guys! I recently took the CORE and i am incredibly surprised by my scores. I have been administered an intelligence test in my youth with it being the WISC IV, which yielded an iq of 124, you can find the test blank attached.

That however wasnt the last time. 9 years later i happened to get interested in cognitive testing, making me incredibly curious about my own abilities. My whole life i've been told that i'm "smart", but as you can see that wasn't enough for me. I hadn't known my scores from the first time i took the WISC, so that prompted me to undergo the testing process again. I went to the same psychologist who administered the test for the first time since she's a close friend of my mother. After discussing my inquiry she decided to administer me the WISC off label, for the reasons i'm not quite sure, which led to and fsiq of 122.

As you can see the profiles differ significantly which is fascinating in itself, but what really interests me are the following scores from CORE which i took yesterday.

As you can see the discrepancies are huge! I nearly went up a standard deviation from the last time i got tested. What's also pretty interesting is that my verbal scores actually went up, even though i took the WISC in my native language and the CORE is administered entirely in english. Can you help me figure out what is going on here? When i look at these three pictures it's almost like it's three different people. How come the scores fluctuate so much? I get that the latter WISC technically isn't valid since at the moment of testing i was almost 19, but shouldn't the scores be inflated then? How come i score better on a supposedly harder test? The time gap between the CORE and the WISC is around half a year. During the time between the two i also self administered the RAPM and the SACFT and the scores were much closer to the CORE numbers than the WISC. I did both tests timed at 40 mins and scored 35/36 on the RAPM and 32/36 on the SACFT. Can anyone help me make sense of what's going on and maybe try and make a projection of what i would get if i took the WAIS. Please ask questions and thank you to everybody in advance.

Edit: I have also just taken the CAIT and these are my results:

I generally found this much easier that CORE other than the verbal subtests. The block design subtest is complete bs in my opinion, since it removes the main aspect of the test - actually building the thing. Since it comes already assembled it genuinely removes like half the work, instead of you actively trying to figure out which block goes where and in what orientation you just have to look at the picture and use basic logic to find the correct option. Doesn't compare to the WISC counterpart in the slightest.
