Session number: 4
Average n-back: 2.67
I am having so much trouble on my 4th session with n=3 , I mean I can’t pass it because my brain always thinks n=2. It can be frustrating at times..

I quoted the following from Jaeggi (2005, pp. 24-25). I changed the syntax and words slightly to clarify that dual n-back training invokes the following cognitive functions.
+Encoding (interpretation of each stimulus).
+Storage (to retain any stimulus relevant to a future decision).
+Rehearsal (to keep the contents of the storage active).
+Matching (to compare every stimulus against the appropriate previous one, i.e., the one n back in the sequence).
+Temporal ordering (to keep the ordinal position of each stimulus tagged, that the present one can be matched).
+Inhibition (to dampen the trace of the oldest stimulus, replacing it with the newest).
+Response selection (the actual execution of the response.
In short, dual n-back training involves static storage processes and dynamic executive manipulation/updating processes. Every load level requires executive processing, since the allocation of attentional resources to independent stimuli is commonly referred to as core property of the Central Executive System (e.g. Baddeley, 1996).

Working-Memory Training Report – Shaun Luttin – Sessions 154, 155
Friday, July 10th, 2009Session number: 9-2, 9-3
Average n-back: 6.15, 7.15!
Duration (min.): 30, 30
Last two sessions.
6.15
7.15!
7.15 is 0.05 below my previous personal best and is the my first time above 7.00 in over 20 sessions. I never have to do that again (but I certainly could).

Working-Memory Training Report – Shaun – Session 153
Thursday, July 9th, 2009Session number: 9-1
Average n-back: 6.30
Duration (min.): 30
My aspiration for period #9 is to stay at or above nAve 6.0 for 16 of 19 sessions. And if not, that’s okay too. Here are my records to date.
Within the score list for eight complete periods of BFPro, there are no records for my first three sessions. Martin, my sense is that I’m starting period 9-1 with today’s score.
It isn’t possible for me to post a graph to the blog; but I would like that. Martin, could you please post my training history as a graph. I would appreciate that!

Working-Memory Training Report – Will – Session 200
Thursday, July 9th, 2009Session number: 200
Average n-back: 6.90
Duration (min.): 25
I hit my new personal best of 6.90 on my 200th session (up from 6.75).
Overall, a strong session, one of my best both subjectively (how I felt about it) and objectively (my n back average).
Still seeing normal fluctuations session to session, as in:
Session 198: 6.50
Session 199: 6.15

Working-Memory Training Report – Michelle – Session 12
Monday, July 6th, 2009Session number: 12
Average n-back: 4.30
Duration (min.): 30
First of all – self-pat on the back for effort: WooHoo! 4.30 on day 12.
Progress so far:
Day 1: 2.30
Day 2: 2.35
Day 3: 2.50
Day 4: 2.80
Day 5: 3.05
Day 6: 3.30
Day 7: 3.50
Day 8: 3.85
Day 9: 4.10
Day 10: 3.80
Day 11: 3.90
Day 12: 4.30
(Days 8 & 9 were done early in the evening and the others around midnight before going to bed. Thanks everyone for the tip – won’t be making that mistake again…..)
I did 5 runs at n=5 this evening. I got bumped immediately back to n=4 after each, but it didn’t really matter, because just to even get half right at n=5 is giving me a real confidence lift.
Why this is so amazing to me is because my working memory has always been far, far weaker than my capacity for abstract thought – enough to cause problems for me (along with an anxiety disorder) in postgraduate work. I even thought that I may have had an impairment in that area, and so sought formal neuropsychological assessment, which I’m in the midst of undergoing now bit by bit every couple of weeks.
I’ve only completed 2 subtests of the WAIS so far (and not the performance subtests), so it will be interesting to see how my fluid intelligence measures go (I will be doing at least some of the performance subtests next week). I did hit the ceiling on the vocab subtest, but my digit span was only 6. The neuropsychologist did say that 6 was above average, but I don’t think it’s that huge – and isn’t currently supporting the flood of ideas that I’m trying to cope with, so I thought I’d give the dual n-back a go, along with MyBrainTrainer, and a couple of other reputable brain training sites.
I really struggled with n=2 when I started, and thought it would be amazing if I could reach a credible n=3 by the end of the first 19 days, so I’m bowled over by the results.
I’m going to show my neuropsychologist my progress, and maybe even ask if we could retest digit span in another month to see if there is any improvement.
Dual n-back isn’t an easy task, but I don’t really care about that – I’m willing to grind away at it. As far as I’m concerned this is now part of my permanent daily mental exercise regime.

Working-Memory Training Report – Will – Session 197
Sunday, July 5th, 2009Session number: 197
Average n-back: 6.75
Duration (min.): 25
A devastatingly bad finish as I was at 7 going into the last 5 blocks…but still ended up with a personal best. I think the problem at the end was not so much loss of focus (in the ordinary sense) but just that I started thinking about hitting 7. At least I was able to hit a new personal best on 4th of July, so no complaints.
And this was a good recovery from my last session (196), in which I dropped to 5.95.

Wednesday, June 24th, 2009Session number: 3-2,3,4
Average n-back: 4.6,4.8,5.2
Slowly improving…I just got a new high…it would have been higher – had a great string of 6…but then fell to 4. Soon I know I will be at 7.
I like martin’s new reporting of the session…how do you do that?
Be well
