How To Optimize Your i3 Dual N-Back Training

When you train with i3 Mindware software, ensure that you maximize the ‘core dual n-back training’ effect by adopting the following principles.

  • Minimize going into ‘automatic pilot’ in the game. Ensure you are always putting in effort and the task is always challenging and absorbing.
  • Ensure that you work at successfully ignoring distracting information – focusing on only what is needed for target ‘matches’. When interference is high, focus and keep your accuracy levels high.
  • In the continuous stream of information, ensure that you continually update the contents of your working memory ‘workspace’, keeping track of the order.
  • Monitor your ongoing performance and try to develop effective intuitions about how to channel your effort, provided you try to stay clear of chunking, attention-hopping and playing the odds strategies.
  • Don’t assume that there is a linear relationship between n-back level and IQ level, and that by doing everything you can to improve your n-back will pay off in terms of IQ gains.
  • Don’t focus on your n-back level at the expense of the principles above.
Completing your full 20 Sessions of i3 Mindware requires a serious, sustained commitment. As this article explains, for brain training to work it requires this kind of time commitment.
.
For this reason, it may be helpful to sign up with a goal-tracking, scheduling app that helps you achieve your 20 day ‘Profile completion’ goal.
.
We recommend signing up to Irunurun which is Desktop and iOS mobile compatible – or the Productive habit tracker for iOS. Simply sign up and set your weekly training goals (e.g. ‘8 half sessions per week’). These apps enable you to not only track your n-back brain training progress, but also any other goals you are working on – such as an exercise routine or an alternate day fasting routine if you are doing brain cross training.
.
The guidelines for your training to build into your schedule are the following:
  • After a brief practice period you need to put aside time for two half sessions of 20-30 minutes, for 20 days, making a total of 20 full Sessions. These 20 days should be completed within a maximum of 6 weeks.
  • You can combine the half sessions together in one sitting (really tough) or you can divide them into morning and afternoon/evening sessions. This means that on average for each week, you need to train 3-4 full Sessions a week. We do not recommend that you train for more than 5 full Sessions a week.
  • After you have completed your 20 full Sessions, you are eligible for the guarantees. After this period, your training will have resulted in long term neuroplasticity change. However, we recommend you continue training for 1-2 hours per week to maintain the gains at their highest level.
