Dual-N-Back training

Dual-n-back is a test of working memory capacity requiring you to maintain a sliding window of two sets of attributes for n previous occurrences. There is a hypothesis that training in this area improves fluid intelligence. Wikipedia informs us that, "Fluid intelligence or fluid reasoning is the capacity to think logically and solve problems in novel situations, independent of acquired knowledge."

Part of my daily routine is a session of dual-n-back training using the Brain Workshop, looking very much like:

Here I will record my, hopefully, improving scores. If scores do improve as hoped then I have to take it on faith that that is commutative to other areas of life. Expect some sort of chart here in the near future.
