Working-Memory Training Report – Will – Session 175

Session number: 175

Average n-back: 6.45

Duration (min.): 25

This was a good session followed by a rocky one; previous session #174 came in at 5.8.

6.45 represents my personal best so far. However, as is plain below, session 174 allowed me to start high (n=8) enabling the high N-back avg for # 175. Thus, a strong case for holistic perspective as opposed to looking at just the session.

I am standing by my earlier assertion that n=8 is not too much harder than 7. Yet, I find 6 and 7 so difficult at this time that I am not getting too many shots at 8. But when I do, I think I can nail 8 quicker than most of the other levels I have hit thus far. This remains just an assertion, though; time will tell.

    Hi Will.

    Congratulations on a new high score!! Well done.

    I agree with you about 8, both subjectively and numerically. Subjectively, I like n=8 and prefer it to n=7, (perhaps because it consists for me of two odd chunks?).

    Also, n=8 requires that we concentrate for only 1/7th more time than n=7. This makes it a much smaller jump than 4 to 5 for instance, which requires a jump in concentration span of 1/4. This only holds, of course, so long as focus doesn’t collapse altogether, as happens sometimes just by adding one more item.

    (Which leads me to wonder whether Shaun’s approach of remembering 6 out of 7 or 7 out of 8 items might shield him to some extent from the phenomenon of focus collapse when we overload??)

    It might shield me, Martin. Who knows. Recently, I’ve been experimenting with remembering 5 out of 5 items on n=5, and remembering 6 out of 6 items in n=6, for instance. So far I have been finding it more difficult; but, that might just be because of lack of practice. The prospect of having two tactics to choose from (remember all, or remember all -1), and thus the ability to have two odd chunks all the time, is a prospect I find motivating.

    Warm regards,

    P.S. I have begun reading a great new book, published in 2009, called “The Overflowing Brain” by Torkel Kilingberg of the Karolisnka Institute. Interestingly, he cites Jaeggi’s study done in 2008.
