Dual N-Back Training
Advanced working memory training. Track both position and letter simultaneously. The gold standard in cognitive training exercises.
How to Train with Dual N-Back
Watch the grid. A square lights up and a letter appears simultaneously.
After each stimulus, decide: did the position match N steps back? Did the letter match?
Click 'Position Match' if only the position matches, 'Letter Match' if only the letter matches, 'Both Match' if both match.
Complete 20 trials. Your accuracy determines your score.
Tips to Improve Your Score
- Start with N=1 and focus on accuracy before increasing difficulty
- Use the three response buttons carefully: Position, Letter, or Both
- Try to maintain the sequence in your mind as a running list
- Practice regularly — working memory improves with consistent training
Frequently Asked Questions
What is Dual N-Back?
Dual N-Back is a working memory training task where you must remember two streams of information simultaneously: the position of a square on a grid and a spoken letter. You must indicate when the current position or letter matches the one from N steps ago.
Does Dual N-Back improve intelligence?
A famous 2008 study suggested that Dual N-Back training could improve fluid intelligence. Subsequent research has shown mixed results. While the IQ-boosting claims are debated, Dual N-Back is widely recognized as an effective working memory training task.
What does N=1 mean?
N represents how many steps back you need to remember. At N=1, you compare the current stimulus to the immediately previous one. At N=2, you compare to two steps back. Higher N levels are more challenging.
