Interesting. Your I-Score is more than four times greater than mine, and yet our profiles are somewhat comparable.
argumzio | 10 months ago Reply
((261.62 + 227.04 + 353.56 + 160 + 341.78) - 5*BASELINE)/5 = 168.8

If we take the gain per number of I-Score points (to get the diachronic improvement), we get (W):

3577*1.688= 5966.36

Your overall score, therefore, is

16271*1.72244 = 28025.82

But if we consider the gains w.r.t. the time invested (X)

(168.8/3577)*100 = 4.719

and

(172.244/16271)*100 = 1.059

which indeed indicates rapid gains (on my part), despite limited experience (Y):

Y=W*X

5966.36*4.719 = 28155

Which is indeed comparable to yours at 29679.

I just wonder what the observed maximum for Y is. Goodness knows it can't stay high for very long, for minimal gains versus experience will drag it down (as is shown by 1A2B3C's stat's compared to my own).

Interpretively, I would consider Y to be the "effective gain" observed from training, and differences would probably be perceptible logarithmically, so:

EY = LOG(Y)

So every integer increase in EY will consist in a noticeable difference in performance.

But I'm sure others could analyze this a little differently.... :)

An excel file has sped up the analysis somewhat. I'd consider multiplying X by EY (call it Z) to get a clearer sense of the "striking" or compound effect the gains would have compared to baseline. This is because a change in the I-Score had no effect on LOG(Y), which makes sense, instead affected mainly by the average gain.

The only problem I can see now is that we must know what the initial I-Score is once the baselines have all been taken into account, so that they can be subtracted from the calculation. A reasonable estimate would probably be 100 I-Score points, which has a negligible (positive) effect on the X*EY calculation. However, if I-Scores aren't given prior to the all of the baselines being taken, then this isn't a problem.

Z will fall or rise as the I-Score increases or decreases, respectively, but rise or fall as X increases or decreases, respectively. If we regard Z as a kind of *hypothetical rarity*, then we can convert it into a percentile ranking by computing SCORE as

1/(1-Z)

And the rest can be computed as hypothetical z-scores (from the normal distribution).

My hypothetical z-score is 1.68 (merely a coincidental value). 1A2B3C's is 0.806. I would consider a hyp z-score of 1 or greater a strong indicator of continued gains despite prolonged training. A score of 2 or more would be remarkable.

The funny thing is, though, cognitivefun could have provided this sort of information to us actually based on the raw empirical data. Too bad that isn't the case, and all I have to go on are these very sketchy numbers and rather unreliable numerical manipulations.

Some example cases that seem to point to the rough reliability of this calculation:

Given

I-Score......AvgGain.....HypZscore
3500.........150.........1.61
1850.........180.........1.999

By the way, BASELINE = 100, since we don't want to count the baseline percent.

Attentional: 261.62
Executive: 227.04
Item Span: 353.56
Perceptual: 160
Working Memory: 341.78

I haven't been playing as much lately, so these might go down. I'm sure I have more room for improvement, but I see little point in doing that as much as others have: my I-Score is only 3577.
argumzio | 10 months ago Reply
100 perceptual
125 attentional
72 executive
114 working memory
209 item span

not to be an idiot but could somebady clarify what the above means, i know what working memory is and if executive is what i think it is it means i'm a slow thinker or i process things slowly.

Those percentages denote your relative improvement from your initial baseline scores. Your executive has dropped, which is odd. Try improving that for a while.

so be blunt simply attempt to complete the challenge as quickly as possible, is that what you are saying?
draft9chem | 10 months ago Reply
just to add an additional side note i was diagnosed with ADHD as a child and continue to suffer from it as an adult at the age of 23
draft9chem | 10 months ago Reply
Very interesting. So the executive tasks *really do* have something to do with executive functioning.

Clearly, that should be your main area of focus.
? | 10 months ago Reply
just finished my drills today, executive functions have improved incrimentally from73.5 to 76.3, i'll check in with you guys at the end of august and let you know my progress.
draft9chem | 10 months ago Reply
However... it is doubtful that they'll actually help you with your problem. Trying for a while can't hurt.
? | 10 months ago Reply
I agree that they represent personal improvement from baseline but I believe that, problematically albeit perhaps necessarily, the initial baseline scores are derived from a small number of one's first few attempts and that these are not fully representative of one's baseline capacities, it being impossible to explore one's limits when temporarily restricted to many tasks' lower levels.

My improvement scores include WM 316 and IS 372, which are just ridiculous if taken to be indicative of amelioration of a fundamental capacity - I may have achieved performances on certain tasks that are three or four times better than on my first few attempts but my memory itself has not improved by that much, if at all.

working memory is different from information consolidation from short term to long term. it simply allows one to retain x amount of data while manipulating it or calculating it.

How are you pulling these scores up?
? | 11 months ago Reply
i can see them when i log with my account , the green pentagon... sorry for my awful english
zaredestanov | 11 months ago Reply
Are these scores in comparison to one's own first performances or the average of others' bests?
? | 11 months ago Reply
i think they are based to other's performances but i don't think to "others" from the this site but others from neurological studies , but i don't know it's just my guess.
