Hello everyone, like the rest of you I've been very and continue to be
excited by the jaeggi study that shows we can increase our score on IQ
tests and become smarter. However, seeing the results from some of the
people who've trained with dual n-back and then afterward take an IQ
test to determine if their IQ has actually increased, has got me
thinking about how valid these IQ tests are. I'm not disputing that
dual n-back isn't effective it has been shown to increase Working
memory, that much I do know.
Here are some examples of people showing dramatic increases in I.Q.
and again I'm simply left dumbfouned by these huge increases in I.Q.
“LSaul posted about his apparent rise in IQ back in October. From what
I remember, he had recently failed to qualify for MENSA, which
requires a score of about 131 (98th percentile). He then got a 151
(99.97th percentile) on a professionally administered IQ test (WAIS)
three months later, after 2 months of regular dual-n-back use.” —MR
Mike L writes “Empirically speaking, however: I took a WAIS-IV IQ test
(administered professionally) around a year ago and got a 110. I took
a derivative of the same test recently (mind you, after about 20 days
of DNB training) and got a score of 121.”
Pontus Granström writes that
“I scored 133 on www.mensa.dk/iqtest.swf
today. I have never scored
that high before I really feel the”dnb thinking" kicking in."
(He apparently took that test about a year ago, and avers that his
original score on it ‘was 122. Well below 130.’)
“I’ve purposely not been doing anything to practice for the tests or
anything else I thought could increase my score so I wouldn’t have to
factor other things into an improvement in iq, which makes
improvements more likely attributable to dual n-back. Before I took
the test I scored at 117, a score about 1 in about 8 people can get
(7.78 to be exact), and yesterday I scored at 127 (a score that 1 in
28 people would get). Its a pretty big difference I would say.”
MY INFORMATION WAS TAKEN DIRECTLY FROM THIS SITE (credit goes to Paul
for posting the link)
There are 2 people who showed no increase in IQ both of them had a
pretty high I.Q. already ( 135 and 140). I remember specifically that
Jaeggi said the lower your IQ the greater you benefit so these two
individual's result could've been from the fact that their IQ is high
already, and one of them stated that daul n-back was not completely
useless and that his digit span and memory have increased noticeably.
Now once again, when I read this I was shocked! Apparently an I.Q. of
125 is the average I.Q. of Medical Doctors and P.hDs. One of the
people who increased their I.Q. from 117 to 127 went from a I.Q. a
little higher than the average college graduate (115) to a P.hD level
I.Q. One other person went from 110 to 121 an 11 point increase, which
is very impressive. http://www.assessmentpsychology.com/iq.htm
After giving you all of this information I want to ask everyone here
are I.Q. tests not a good indicator of intelligence? Is working memory
(gF) a much better predictor of intelligence than once previously
thought? Taking dual n-back into consideration will psychologists have
to renorm the I.Q. test again? And this question is probably the one I
really want answered. First a quick background. My I.Q. is only 114 I
took the I.Q. test from this site http://www.highiqsociety.org/iq_tests/
After seeing my result I was very sad and dissapointed.
I'm developing a comprehensive and grueling work out regime for my
brain in which I will try to increase my I.Q. as much as possible. Of
course this will be done without actually practicing for the I.Q.
test. What I will do is play a lot of dual, triple, quad n-back,
exercise regularly, play chess, practice increasing my vocabulary, and
basically anything that can increase your I.Q., but again without
actually taking I.Q. tests or doing I.Q. related questions. I will be
doing this for 3-4 months and then take the test at http://www.highiqsociety.org/iq_tests/
again. I will also try to empirically determine whether my gains in
I.Q. are practical.
So basically after exercising my brain heavily for 3-4 months I will
take the I.Q. test and see if I've increased my I.Q. If my I.Q. has
increased I will try to determine if the increase in I.Q. is practical
and beneficial to me in the real world. To give one example. I did
terrible in intro to college physics and had to drop the class because
I was doing poorly. If my I.Q. were to increase by say 10 points to
124, then I should not have a problem with physics and should expect
to get a B if not an A in the class. So I want to know if anybody else
wants to join me in this study I'm about to undertake. I want to know
if dual n-back increaes academic performance.
