Working-Memory Training Report – martin – Session 172

Session number: 10 – 1

Average n-back: 7.9

Duration (min.): 45

Afternoon. Ran.

(No breaks, no meditation, no neuroprogramming.)

Start of a new profile. Always a weird experience to work one’s way up through unfamiliar n-levels. I felt a little unfocused during the first seven blocks. But this was followed by a period of very good focus, staying at 9 and 10 for almost the entire second half.

    Hi Martin et al,

    The MENSA Vancouver branch of MENSA Canada invited me to be a panelist at an informal dialogue about IQ increase. The dialogue date is set for late August, and I would like to casually read up on the topic.

    My knowledge of IQ increase is humble at best. Could you Martin, and the rest of the BFPro community, please send me information about IQ increase. That will help me to make a stronger contribution to the dialogue.

    Warm regards,
    Shaun

    Hi Shaun.

    That’s great. I’m sure you will have much to contribute. I’ve been thinking about what I could provide to help. I’ll keep you posted.

    Martin

    I’m crunch time busy over the next few days but will post on this in the next few days as well.

    Thanks Martin and Will. Martin, I have started to read Jaeggi’s dissertation. I like it.

    Shaun, I have a paper showing an increase in timed RAPM score as well as in backward digit span in vegans who took creatine supplements for 6 weeks.

    I never tried it as I don’t like the idea of supplements, and am not a vegan, but I thought it was interesting nonetheless.

    Here’s the reference:

    Rae C., et al. Oral creatine monohydrate supplementation improves brain performance: a double-blind, placebo-controlled, cross-over trial. Proc. R. Soc. Lond. (2003) 270, 2147–2150

    I have a copy, let me know if you need me to send it to you.

    You may also want to look at Torkel Klingberg’s work. The most interesting one I have found is the latest paper by McNab that describes changes in dopamine receptor density in brain regions thought to be related to working memory after 5 weeks of training with a tasks similar to n-back.

    This is what really clinched it for me, and what may help sway your audience. The idea that the task causes biochemical changes in brain regions previously thought to be related to working memory is remarkable.

    You can access them at http://www.klingberglab.se/pub.html

    Klingberg also recently published a book called “The Overflowing Brain”. I haven’t read it, but I believe it delves into the idea of cognitive enhancement.

    Let me know what you find. I’d be interested in reading any material you come across that I may not have seen.

    I’d suggest starting a list of references that we can keep adding to, and keeping a link to it on the blog.
