Random notes:
- they didn't use a speeded Raven's, and they observed no gains on it
> However, such power limitations do not readily account for our failure to replicate a transfer of WM training benefits to measures of fluid intelligence (as was observed by Jaeggi et al., 2008), since we did not find even a trend for improvement in trained participants on Raven's APM. Beyond statistical explanations, differences in the training paradigms used for the two studies may explain the differences in transfer effects. The training program used by Jaeggi et al. (2008) involved 400 trials per training session, with a dual n-back training paradigm designed to emphasize binding processes and task management. Conversely, our training paradigm included only 32 trials per session and more heavily emphasized maintenance in the face of distraction. Finally, the seemingly conflicting results may be due to differences in intelligence test administration. As was pointed out in a recent critique (Moody, 2009), Jaeggi et al. (2008) used atypical speeded procedures in administering their tests of fluid intelligence, and these alterations may have confounded the apparent effect of WM training on intelligence.
> The Raven's APM is not a speeded test. All participants completed the test well within 45 min.
It's quite surprising to me that the reading gains are linked more
strongly with spatial improvements than verbal span improvements.
> Our findings, which suggest an effect of WM training on Stroop and reading comprehension performance, can be informed further by a closer examination of interindividual differences in the influence of training on WM capacity itself. As we have already shown above, participants for whom training promoted an increase in WM span (i.e., successfully trained participants) exhibited stronger improvements for each transfer measure. Taking a more nuanced view, one might further expect to find a correlation between WM improvements and gains on the transfer measures, with greater improvements in those for whom the WM training was most effective (i.e., produced larger increases in WM span) and weaker improvements in those for whom it was relatively less effective. Despite our relatively small sample size, we accordingly tested correlations between WM span increases and both Stroop and reading comprehension improvements. For the Stroop test, the correlations were weak [r(18) = 2.01 for verbal WM; r(18) = .12 for spatial WM] and not significant. However, the results from the reading comprehension measure were more encouraging. The correlation between verbal WM increases and Nelson-Denny improvements was modest [r(18) = .24, p = .13], and there was a strong and statistically significant relationship between trained participants' spatial CWM span increases and reading comprehension improvements [r(18) = .49, p
I wonder how one is to interpret that.

I can't even parse your second to last sentence.
No one is saying that Jaeggi faked her research. What is being said is
that the 10 minute time limit makes the test test something else. You
know this.
If 10 minute time limits are so common, then why is Jaeggi's
justification a footnote citing a footnote citing unpublished
research?
Why does Jaeggi's more extensive followup with the elderly (which we
discussed not that long ago) not show Gf boosts?
Why does this not show Gf boosts?

Since it's so well established that timing has little influence on the tests there's no reason to make a big deal of it, since it's nothing controversial. In fact RAPM is timed in one way or another! I guess RAPM could be considered speeded compared to mathematics olympiad or really hard math problem. In one way or another it's linked to our ability to think efficiently, if a 3-min "oddman out" is correlated with 0.8 I find it hard to believe that a 10 min RAPM test should have a zero correlation with Gf/G.

comprehension? Is the test of reading comprehension similar to what
one would see on the GMAT or GRE? Perhaps a strong spatial WM allows
one to quickly gather key words and information via skimming, thus
being able to answer the question quicker, or quickly find the answer
by looking at the question first.

It does show that young adults do improve on certain cognitive
measures (most likely ones most closely related to WM), while there
isn't enough data on older adults to draw a conclusion. I do have a
feeling that cognitive functions can be improved in the elderly, since
earlier studies have shown improvements in WM and processing speed.
Perhaps, Gf relies more on the synergy of many cognitive functions, as
opposed to just WM. I wonder if a regimen designed to train a
vartiety of cognitive functions could improve Gf.
Other interesting points, both the young and the elderly showed
similar knowledge gains after vocabulary training. This goes against
the notion that younger people are faster learners.

This article says that everyone finished the Raven's within the 45
minute time limit. This is emphatically not true of Jaeggi 2008,
where, IIRC, no one finished the whole thing ever.
And again, as I've said time and time again, the 10 minute Raven's may
be entirely processing since unless you're hellishly quick, you won't
get to the hard questions which would reveal Gf changes. If everyone
can answer the easy questions, and you only have time for the easy
questions, then a minimal correlation with Gf is not so strange.

I agree with Argumzio on this one. I don't know what those scores and
tests are that you mention, and I don't think they really add
anything. You don't even mention how long passed between those scores
and how many levels of DNB improvement that interval saw. The IQ score
section is for pairs of scores on the same test.

The article says
'Finally, reading comprehension was measured with the Nelson- Denny
Reading Test (Forms G and H used in counterbalanced fashion across
sessions), using standard test procedures and allowing 20 min for test
completion.'
The NDRT seems to have a website and sample questions:
- http://www.testprepreview.com/ndrt_breakdown.htm
- http://www.testprepreview.com/nelson_denny_practice.htm
It seems to be GRE like, but much easier of course. Your skimming
suggestion seems possible to me; I've known people who don't read the
text first and work question by question. (I've always preferred to
read carefully and then answer the questions, only going back when I'm
unsure.)

Motives? Convenience. Carelessness. Publish or perish. Money. Take your pick.
From Jaeggi 2008:
> Transfer tasks: We used standardized fluid intelligence tests, consisting of
visual analogy problems of increasing difficulty. Each problem presents a
matrix of patterns in which one pattern is missing. The task is to select the
missing pattern among a set of given response alternatives. For the experi-
ment with eight training sessions, we used the Raven’s Advanced Progressive
Matrices (RAPM) test, set II (35), whereas for all other experiments, we used
the short version of the Bochumer Matrizen-Test (BOMAT) (36), a more
difficult variant of the RAPM. For the RAPM, we used parallel forms for the
pre- and posttesting by dividing the test into even and odd items (24); for the
BOMAT, we used the published A and B versions. To keep the pre- and posttest
sessions short enough, we allowed limited time (10 min) to complete the task,
and the number of correct solutions provided in that time served as the
dependent variable.
Nothing about skipping to the harder questions.

Gwern, while your FAQ is largely based and pre and post results
comparing the same test, it isn't entirely so. For example, an early
post mentions failing to pass the mensa entrance exam then later
getting over a 150 on the WAIS. A large amount of it is ancedotal.
I don't think that's a problem, since people can see that from reading
it. While, there has been some suggestion that the test itself might
not be great, I'm not sure that the test you've linked too have been
proven any better. I think the Gigi is decent since the same folks
put it out that put out the eCMA that arguizmo took a couple of times
and praised. In any case, maybe a wait and see attitude regarding
this new test ought to be adopted. Pontus says that he's not scored
even close to that before on matrix type test. I'd just assume he's
speaking I good faith.
In any case, I hope your woes abate Pontus.

norm their test. If they are basing it simply on participants through
their website alone, then the norming would be contaminated, since
those who take online IQ tests are likely not representative of the
general population. (i'm not saying they collecting data using this
method, but it would be the one of the cheaper ways of doing so) In
addition, you will have people who will take the test multiple times,
skewing the average score on the test. Yes, they are controling
retest effects through email confirmation, but that isn't always
reliable.

But both the Mensa tests and WAIS have long track records; and I do
put in a long comment noting that there are differences that could
lead to a higher WAIS percentile than the Mensa.

Part of the reason I'm not too interested in Pontus's scores on this
new test is because Pontus is already in that section - with a nice
pre/post pair of scores on www.mensa.dk/iqtest.swf
Why include 2 positive results by the same person? It'd be another
thing if Pontus were reporting declines, though.

The effect of this restriction was to make it impossible for subjects to proceed to the more difficult items on the test. No it was to raise the ceiling of the test and avoid ceiling effects which would make it impossible to notice any differences in G/Gf.
He also states that BOMAT puts added emphasis on subjects’ ability to hold details of the figures in working memory.
RAPM is one of the tests that requires most working memory and the score is lowered by 3/4 of SD from it. It's not that strange to believe that an increase of WM would take the score the other way.

I messed around with the training in '09 and worked by way up to 7 back. I tried to do it 5 days per week, but 3 to 5 days was probably more representative of a typical week. Around August of last year, I stopped entirely. I didn't stop for any particular reason; I think life just got in the way and I never started again. A couple of weeks ago, I decided to start playing again. (At 43, I need to start doing what I can to prevent Gf from going down the drain *too* fast.) I've played maybe 6 times now over a two week or so period and only did a full 20 trials on two of those days. I'm amazed that after such a long time away, I'm almost right where I left off (75% on 6 back). I assume I'll probably be back up to 7 back tomorrow. Weird.

It's pretty light on details, but at least now we have more than just
the abstract. (May remember that we discussed it a few months ago but
couldn't find the actual paper.)
That said, I wonder how much weight to put on it.
1. The Raven's test was allotted 25 minutes, which while not as absurd
as Jaeggi 2008, still isn't as long as it might be
2. This is Chinese research; they aren't known for high quality or
reliable research. (See any of the articles in
http://www.google.com/search?q=Chinese%20research%20plagiarism%20fraud
)
3. There's something weird about their subjects/data. Look at the last
page - the original average IQ in their control group is almost 10
points above their experimental group? (Not that only 10 students in
each group is stellar either.)

There's a lot of fraud, mainly plagiarism and ghostwriters, however this does not imply that everything is faked nor is it very likely.
They recruited 2x10 students, with a mean IQ-difference of 7 points, nothing weird at all, epecially considered that they were technology students and this has absolutley no scientific meaning, infact it points to the fact that they were honest.
The quality seems fine, they kept strict training protocols to make sure that they trained as instructed. Comparing to the Cambridge study where they only spent a few minutes on STM-tasks to prove that WM-training didn't work, al though nobody actually trained on WM-tasks. This can be a serious case of fraud.

one study confirming Jaeggi 2008 (in addition to her 2010). It was
"published" on the same level as this gabor-thing (means on some
conference when they dont need proper english). But it had more
participants, did not use (nearly unusable) SPM but RAPM, and even
gave all the participants full 40 minutes and all the questions (36).
Results were really exciting, but as the author still felt the study
was not professional enough, he refused to make bold claims like
"intelligence double-increase in training group compared to controls!"

And again, as I've said time and time again, the 10 minute Raven's may
be entirely processing since unless you're hellishly quick, you won't
get to the hard questions which would reveal Gf changes. If everyone
can answer the easy questions, and you only have time for the easy
questions, then a minimal correlation with Gf is not so strange.
I find this statement interesting, since it's well known that more intelligent people work faster with easier items. Meaning that timed performance on the easy question would be a very good indicator of relative standings of the intelligence scores, meaning that the G correlation is high.
Quote from the report Qualitive and Quantitive properties of an intelligence test (files section)
"Correlations between the Raven’s test scores and time measures of the Letter
Series test tend to decrease as difficulty increases: people with high scores on
fluid intelligence tend to work faster than average when test items are easy, but
when the test becomes more difficult they perform at much the same speed as
people who have lower fluid intelligence scores."

That's useful; I especially like the part that mentions that the gains
are still there 3 months later. I'd been putting off adding an FAQ
section about whether breaks are harmful and gains durable, but that
gives me a useful cite, and so I've finally added it.

Abstract
The acknowledged high relationship between working memory and
intelligence suggests common underlying cognitive mechanisms and,
perhaps, shared biological substrates. If this is the case,
improvement in working memory by repeated exposure to challenging span
tasks might be reflected in increased intelligence scores. Here we
report a study in which 288 university undergraduates completed the
odd numbered items of four intelligence tests on time 1 and the even
numbered items of the same tests one month later (time 2). In between,
173 participants completed three sessions, separated by exactly one
week, comprising verbal, numerical, and spatial short-term memory
(STM) and working memory (WMC) tasks imposing high processing demands
(STM–WMC group). 115 participants also completed three sessions,
separated by exactly one week, but comprising verbal, numerical, and
spatial simple speed tasks (processing speed, PS, and attention, ATT)
with very low processing demands (PS-ATT group). The main finding
reveals increased scores from the pre-test to the post-test
intelligence session (more than half a standard deviation on average).
However, there was no differential improvement on intelligence between
the STM-WMC and PS-ATT groups.

What study was that? Playing coy isn't very helpful.
Also, by her 2010, I take it you mean

Keep in mind, at the time my FAQ hardly existed, and I don't think
anyone since has mentioned it. But now that it's been commended to my
attention, I've added a section on it. I mean, if I was willing to put
in a section on the Chinese study, I suppose polar's study isn't
*that* much worse. (Even if it was never published; I assume polar
would've told us if it had been.)

Dunno. Ask her. 2010 is heading toward an end - what's she been doing
ever since?

Veteran group members probably won't learn anything from it, though I
thought college students and new members may appreciate it's
simplicity (vs trying to read some of the posted research papers with
no related background experience).
It actually gave me an idea... Shouldn't we be playing n-back in
different environments? I implemented playing 2+ similar modes each
day awhile back and I think it's beneficial (even if it's only because
it makes it easier to sustain attention if you have ADHD!)
Jonathan Toomim
applies to declarative (i.e., semantic and episodic) memory. It
probably does not apply to implicit (e.g. procedural) memory, which is
what n-back should produce.
Playing several different modes in one day is very a different matter,
and one which I suspect is a good idea. Sounds akin to cross-
training: the best way to learn free throws is to practice shooting
hoops from all over the court, not to just practice free throws,
according to Art Shimamura, the psych professor who taught the memory
class I took a few years ago (IIRC).
