DNB group survey

This is an anonymous questionnaire by and for members of the "Dual N-Back, Brain Training & Intelligence" google discussion group. Its purpose is to summarize a basic overview of members opinions and habits. You see all of the questions now. None of them is required, but the more you put in, the more you get. Should you have any comments or suggestions during the process, there's a place for them at the end. Thanks & enjoy. © polar
