I am by no means an expert on this, but I am also a bit sceptical
about the WM gains. There is alot of chunking going on in DnB, at
least if subvocalize like I do. Might this not just mean that they
improved their chunking skill and therefore their digit span results?

The top row shows the sequence across trials (A, B, C, D, etc.) of visually presented stimuli in a 4×4 grid (the visual stimuli were presented on a standard 1280×1024 pixel computer display). A picture of a face appeared in one of the 16 possible grid positions on each trial. Simultaneously, with the presentation of these visual stimuli on the computer display, participants heard words over headphones (second row in the figure). Participants were required to indicate, by button press, whether the trial was a 'target trial' or not. Targets could be visual or auditory. In the example here, Trial C is a visual target. That is, the face in Trial C is presented in the same location as the face in Trial B (i.e., n = 1 positions back). Note, the faces are of different actors. For visual stimuli participants were asked to ignore the content of the image and solely attend to the location in which the images were presented. In the current example, Trial D was an auditory target trial because 'Evil' is the same word as the word presented in Trial C - n positions back (where n = 1). Each block consisted of 20+n trials.

As can be seen in Figure 3, there was a trend toward a significant group difference in Gf (RPM scores) at pre-training, p≤0.10. This raises the possibility that the relative gains in Gf in the training versus control groups may be to some extent an artefact of baseline differences. However, the interactive effect of transfer as a function of group remained significant even after more closely matching the training and control groups for pre-training RPM scores (by removing the highest scoring controls) F(1, 30) = 3.66, P = 0.032, ηp2 = 0.10. The adjusted means (standard deviations) for the control and training groups were now 27.20 (1.93), 26.63 (2.60) at pre-training (t(43) = 1.29, P>0.05) and 26.50 (4.50), 27.07 (2.16) at post-training, respectively. Moreover, there was a trend for the gain in Gf to be positively correlated with improvements in n-back performance across training r(29) = 0.36 at P = 0.057, suggesting that such gains were indeed a function of training....Although the Gf transferable gains we found appear to be somewhat related to training gains and the effects remain when we trim the groups to provide a better match for pre-training Gf, it is important to note that some degree of regression to the mean may be influencing the results.

New Article from Aaron Hockley |
Salvaging Shitty Light at the Crooked River Bridge Posted: 29 Sep 2011 08:00 AM PDT A few weeks ago I was invited to speak about photography at a real estate conference in Central Oregon. My return trip from Bend brought me to the Crooked River bridges including the railroad bridge which sits about 320 feet above the water below. Given the opportunity to photograph an interesting structure, I pulled into the rest area adjacent to the highway and river. The Problem: Midday LightPhotographers know that midday light is bad. There’s a reason that photographers get up early and stay up late… that’s when the best light occurs naturally. The high sun angle in the middle of the day results in blown highlights and harsh shadows. Given that I arrived at the bridge around 12:30pm with bright sun and an air temperature around 95 degrees, things couldn’t have been much worse. I present to you a program-mode image: Making Something Out of NothingI knew in the field that a “regular” photo wouldn’t cut it if I wanted anything presentable from this little stop. While there, I decided I’d see what I could do in the digital darkroom to create something that wouldn’t be purely a photograph but rather a bit of digital art based on a photograph. I made several images in the field; a few days ago I spent about 45 minutes creating the following image. Is it a photograph? Is it digital art? Does it matter what we call it? How’d I do? (Yeah, I know the image is missing a train…) |

Well, I've tried it... twice. First during the day. It was pretty good
feeling and afterwards for a while I had a different perception of my
body and surroundings. Like more details caught my attention.
Second time when I went to sleep. I've felt really relaxed and by the
end I was loosing my conciousness. Generally speaking, it works really
good and gets you relaxed. (I don't have a sleep tracker, though.)

Very cool. The emotional thing is nifty, of course, but the real value
for me is the IQ stuff.
The emotional aspect seems to be just replacing the 'neutral' existing
stimuli like colors or letters or piano keys with more loaded ones:
> The figure depicts a block of the emotional version of the dual n-back task (training task) where n = 1. The top row shows the sequence across trials (A, B, C, D, etc.) of visually presented stimuli in a 4×4 grid (the visual stimuli were presented on a standard 1280×1024 pixel computer display). A picture of a face appeared in one of the 16 possible grid positions on each trial. Simultaneously, with the presentation of these visual stimuli on the computer display, participants heard words over headphones (second row in the figure). Participants were required to indicate, by button press, whether the trial was a 'target trial' or not. Targets could be visual or auditory. In the example here, Trial C is a visual target. That is, the face in Trial C is presented in the same location as the face in Trial B (i.e., n = 1 positions back). Note, the faces are of different actors. For visual stimuli participants were asked to ignore the content of the image and solely attend to the location in which the images were presented. In the current example, Trial D was an auditory target trial because 'Evil' is the same word as the word presented in Trial C - n positions back (where n = 1). Each block consisted of 20+n trials.
(If you look at Figure 1, example stimuli words are dead, hate, evil,
rape, slum, and a picture of a very angry male face.)
The difference doesn't seem to change progress on n-back in either
group, which is good since if there were differences, that would be
troubling eg. if the affective n-back group didn't increase as many
levels, that would make any following results more dubious:
> Performance of the two n-back groups pre- to post- training did not differ significantly on either the neutral F(1, 27) = 1.02, P>0.05 or affective F (1, 27)<1 n-back tasks. Similarly, the control group showed a significantly greater pre- to post-training improvement on the feature match task they trained on, compared with the n-back groups F(1, 42) = 41.09, P<0.001, ηp2 = 0.67.
And as expected, both DNB groups increased WM:
> As predicted, participants in the training group showed a significant improvement on digit span F(1, 28) = 33.96, P<0.001, ηp2 = 0.55. However, this was not true of controls F(1, 15) = 1.89, P = 0.19, ηp2 = 0.11, and the gain was significantly greater in the training group participants compared to controls F(1,43) = 5.92, P = 0.02, ηp2 = 0.12.
The RPM scores are... a little troubling. The DNB groups gain ~1 point
(question), and the control group falls ~2 points after starting off
~2 points higher. In other words, if the control group had not fallen
so much, the DNB groups would at no point have scored higher! They
don't seem to think it's a problem, but even if the result stands,
it's certainly not impressive:
> Replicating their results, we found a significant gain in Gf scores in the training group over and above gains on the digit span task F(1, 26) = 3.00, P = 0.05, ηp2 = 0.10. In contrast, the control group showed a non-significant decrease in Gf, F<1, and the critical group by time interaction was significant, F(1, 40) = 7.47, P = 0.01, ηp2 = 0.16.

FWIW, they don't mention administering the RPM in any speeded fashion:

Anyone know what time this starts? Can't seem to find it on their

Its a 5K run done in different cities where you get blown with colored

As of right now the cities for 2012 are a bit far away, but it looks
like registration is going to open for Washington DC and Boston for
September 2012. So you have plenty of time to plan and save up. I
definitely plan on doing this and wanted to put the feelers out to see
