N-back training Should I do multiple daily sessions, or just one? Others do one session in the morning and one in the evening so they can focus better on each one.
There is some scientific support for the idea that evening sessions are better than morning sessions, though; see Kuriyama on how practice before bedtime was more effective than after waking up. Strategies The simplest mental strategy, and perhaps the most common, is to mentally think of a list, and forget the last one each round, remembering the newest in its place.
This begins to break down on higher levels - if one is repeating the list mentally, the repetition can just take too long. Surcer writes up a list of strategies for different levels in his thread. Are strategies good or bad? People frequently ask and discuss whether they should use some sort of strategy, and if so, what.
A number of N-backers adopt an intuition strategy. Rather than explicitly rehearsing sequences of letters f-up, h-middle; f-up, h-middle; g-down, f-up…they simply think very hard and wait for a feeling that they should press a l location match.
Some, like SwedishChef can be quite vociferous about it: The challenges are in helping people understand that dual-n-back is NOT about remembering n number of visual and auditory stimuli.
Initially, most students of dual n-back want to remember n items as fast as they can so they can conquer the dual-n-back hill.
They use their own already developed techniques to help them remember. They may try to hold the images in their head mentally and review them every time a new image is added and say the sounds out loud and review the sounds every time a new sound is added.
This is NOT what we want. We want the brain to learn a new process that intuitively recognizes if an item and sound was shown 3 back or 4 back. In theory, this new process translates into a better working memory, which helps you make connections better and faster. I mean, sure, you can intuitively remember you heard the same letter or saw the square at the same position a few times ago, but I fail to see how you can feel it was exactly 6 or 7 times ago without some kind of active remembering.
On your score sheet, the first picture, using the intuitive method over 38 days of TNB training in 44 days your average n-back increased by less than. You were performing much better before. With your neurogenesis experiment, your average n-back actually decreased. I would NOT recommend you [train the visual and auditory task separately] if you want to train the dual-task the one we used in our study.
The reason is that the combination of both modalities is an entirely different task than doing both separately! If you do the task separately, I assume you use some rehearsal strategiese. Processes that then might help you in the performance of other, non-trained tasks and that is our ultimate goal.
So, it is not important to reach a 7- or 8-back… It is important to fully focus your attention on the task as well as possible. I can assure you, it is a very tough training regimen….
But eventually, you will see that you get better at it and maybe you notice that you are better able to concentrate on certain things, to remember things more easily, etc.
Unfortunately, doubt has been cast on this advice by the apparent effectiveness of single n-back in Jaeggi By this account, one reason for having obtained transfer between working memory and measures of Gf is that our training procedure may have facilitated the ability to control attention.
This ability would come about because the constant updating of memory representations with the presentation of each new stimulus requires the engagement of mechanisms to shift attention.
Also, our training task discourages the development of simple task-specific strategies that can proceed in the absence of controlled allocation of attention.
Even if they do, they may not be a good idea; quoting from Jaeggi We also proposed that it is important that participants only minimally learn task-specific strategies in order to prevent specific skill acquisition. We think that besides the transfer to matrix reasoning, the improvement in the near transfer measure provides additional evidence that the participants trained on task-underlying processes rather than relying on material-specific strategies.
Hopefully even if a trick lets you jump from 3-back to 5-back, Brain Workshop will just keep escalating the difficulty until you are challenged again. When I was doing visual psychophysics research, I heard from my labmates that this question has been investigated empirically at least in the context of visual psychophysicsand that the consensus in the field is that using feedback reduces immediate performance but improves learning rates.
I would also expect it to apply to Brain Workshop.There are lots of jobs available in Detroit, and Detroit at Work is the best place to search for all of them.
