Dual N-Back Training Options
Here you choose the type of n-back training you want to do.
‘2G’ is a second generation development of the original Jaeggi et al (2009) dual n-back training task. It is the traditional dual n-back but with interference control (which improves n-back training) and speed/rhythm control.
‘Stroop’ is a unique n-back on the market that maximizes the need for inhibition of distracting information via what is called the Stroop Effect.
Both 2G and Stroop games come with the money-back IQ and working memory increase guarantees.
What Do You Do In Standard N-Back Training?
The Dual Training Mode works in exactly the same way as in either Visual Training Mode or Audio Training Mode, starting with an ‘n-back’ = 1. The difference is that you now have to keep track of not just one sensory modality but two – simultaneously! At the same time as the square moves from location to location, you hear phonologically distinct letters. You must press the ‘F’ key if there is a visual match and the ‘L’ key if there is an audio (letter) match. If there is a match for both at the same time, you must press both the ‘F’ key and the ‘L’ key together. In the diagram below there are 2 spatial (square) matches and 2 verbal (letter) matches in 6 moves.
.
If you get 90% correct or more in a block of 20 moves for both the spatial task (changing square), and the audio task, the memory ‘n-back’ gap for the next set of 20 moves increases 1 n-back level. If you get 70% or less in either visual or audio, the gap decreases 1 n-back level. Otherwise the n-back level stays the same.
After each 10 block training session a window will appear giving you graphical feedback on how well you have done, as described above. Close the graph, and click on the ‘N=x’ arrow button (that indicates your current n-back level) to take you to the Session window. You can check out your performance stats here.
Your Aim: Increase Your N-Back Level & 2G Score!
Your aim over the full 20 Sessions of training – spaced out over a maximum of 1 month (31 days) – is to increase your n-back level – a measure of your working memory capacity, as well as your overall 2G score. The n-back gap could increase all the way to a 5-back or beyond as the working memory training takes effect. With more working memory capacity, you have effectively more ‘RAM power’ in your brain, and your intelligence will increase. Switching on ‘hyper n-back’ (which you can do between blocks) increases your 2G score which is mainly based on your n-back level.

What Do You Do In Stroop Dual N-Back Training?
Stroop dual n-back training is dual N-back training with arrows that can appear in 4 locations, and words that can appear in 4 colors. There is no audio. The dual n-back task itself that can come in 4 combinations, indicated by the response key icons at the bottom of the game screen.
Direction and Color: In this mode (shown in the screenshot here), you must look for n-back matches for the direction of the arrow (ignoring the arrow’s location) and the color of the word, (ignoring the word meaning).
Direction and Word Meaning: The icon for word meaning is ‘ABC’. In this mode you must look for n-back matches for the direction of the arrow (ignoring the arrow’s location) and the meaning of the word – i.e. what you read
Location and Color: The icon for location is the standard location icon for 2G n-back. In this mode, you must look for n-back matches for the location of the arrow (ignoring the arrow’s direction) and the color of the word, (ignoring the word meaning).
Location and Word Meaning: In this mode you must look for n-back matches for the location of the arrow (ignoring the arrow’s direction) and the meaning of the word – i.e. what you read (ignoring the color of the word).
Any of these combinations can appear (randomly) on each block you play the game. This game can create a lot of interference from the second dimension of the stimuli, which helps with IQ transfer and the strengthening of executive control.
Your Aim: Increase Your N-Back Level & 2G Score!
Your aim over the 40 10-block half sessions of of training – spaced out over 4-6 weeks – is to increase your n-back level – a measure of your working memory capacity – and overall 2G score The n-back level could increase all the way to a 5-back or beyond as the working memory training takes effect. With more working memory capacity, you have effectively more ‘RAM power’ in your brain, and your intelligence will increase. Switching on ‘hyper n-back’ (which you can do between blocks) increases your 2G score which is mainly based on your n-back level.
