Questions
What is dual n-back training?
Dual n-back is a working-memory task: compare a position and a sound with the ones presented N turns earlier. The two streams are evaluated separately.
Can I start as a beginner?
Start with N=1 to learn the rhythm, then explore N=2 and higher levels. Session results help you understand your accuracy on the task, not your IQ.
