Dual N-Back

Dual N-Back is a scientifically-backed brain training Chrome extension designed to enhance your working memory and fluid intelligence (IQ). By engaging with both auditory and visual stimuli sequences, users challenge their memory to match current signals to previous ones, effectively sharpening cognitive abilities.

The app offers extensive customization, allowing users to select difficulty levels (N-Back settings), trial counts, signal durations, and match rates. Visual cues include positions, images, colors, and more, while audio cues range from letters to piano keys. Regular 20-minute training sessions can significantly improve brain performance, as supported by research from Johns Hopkins University and the Proceedings of the National Academy of Sciences.
