More seriously, working memory can be useful since it allows one to grasp more of the structure of something at any one time. Things simultaneously! He will deadlock forever, unsure either what to do with this foo, or unsure what exactly String with the input, or he can know that the function processInput uses a string, but he can’t remember these 2 But unfortunately, our programmer can know that the variable foo contains a HowĬould he write anything? To write a correct program, he needs to know simultaneously 2 things - what a variable, say, contains,Īnd what is valid input for a program. Imagine a poor programmer who has suffered brain damage and has only enough working memory for 1 definition at a time. ‘how much stuff you can think about at the same time’. 10 It’s not too hard to see why working memory could be so important. Learning and also just general intelligence. Results that task switching can be trained and that it transfers 9, but how useful this is and how well the BW modes train this are unknown. Some of the more elaborate modes seem toįocus heavily on shifting the correct response among various modalities - not just sound, but left/right, eg.

Link between WM and performance on IQ tests has been disputed high WM as measured by OSPANĭoes not correlate well with performance on hard Raven’s questions 7 and the validity of single tests of WM training has been questioned 8.)īrain Workshop offers many modes, some far more elaborate than simple Dual N-back no research has been done on them, so littleĬan be said about what they are good for or what they train or what improvements they may offer Jaeggi 2010 seemed to find Single N-back better than Dual N-back. 6 Performance on DNB has complicatedĬorrelations with performance on other tests of working memory or IQ, so it’s not clear what it is tapping into. Or improving manipulation of WM contents (rather than WM’s size) or somehow training IQ directly. Of WM like reciting lists of numbers, raising the question of whether N-back works via increasing WM or by improving self-control

Later research found that performance and improvement on N-back seems to correlate better with IQ rather than classic measures And N-back is a family of tasks which stress attention and WM. Trainable, and so improving WM would hopefully improve IQ. May use the same neural networks 4, suggesting Happens, WM predicts and correlates with IQ 3 and (WM), and hopefully your intelligence (IQ 1).Ĭognitive processes tend to overlap and seem to go through one central bottleneck. Training intended to expand your working memory
