Dual N-Back Training
Each round, a colored square lights up on the grid. Your job: remember what you saw N rounds ago. If the square is in the same position as N rounds ago, press Position (A). If it's the same color, press Color (L). You can press both, one, or neither. You have 3 lives — each mistake costs one.
FAQ
Dual n-back is a working memory training task where you simultaneously track two streams of information (position and color/sound), checking if the current stimulus matches what appeared N steps back.
Research by Jaeggi et al. (2008) showed gains in fluid intelligence after dual n-back training, though later studies have been mixed. It reliably improves working memory capacity regardless.
Most beginners start at 2-back. Reaching 3-back consistently is good, and 4-back or higher is excellent. The key is sustained daily practice of 15-20 minutes.
About this test
Dual n-back is the gold standard of cognitive training, backed by neuroscience research. It simultaneously trains two components of working memory by requiring you to track position and color at the same time.
How It Works
A square appears in a grid position, and a color is shown. You must indicate whether the current position or color matches what was shown N steps ago. As you improve, N increases, demanding more from your working memory.
Research Background
The dual n-back paradigm was developed by Wayne Kirchner in 1958 and popularized by Susanne Jaeggi's 2008 study showing transfer to fluid intelligence. It remains one of the most studied cognitive training interventions.
Training Tips
- Start at 2-back and master it before moving up
- Train daily for 15-20 minutes for best results
- Focus on the position stream first, then add color
- Do not be discouraged by mistakes — they drive adaptation
