dual n-back

Dual N-Back is a cognitive training exercise designed to enhance working memory and fluid intelligence. In this task, participants track two streams of information simultaneously: the position of a square on a grid and a sequence of spoken letters. The goal is to identify when either the position or the letter matches what was presented “N” steps back in the sequence. By challenging the brain to manage and recall multiple pieces of information at once, Dual N-Back aims to improve mental agility and overall cognitive function, which may benefit general knowledge acquisition and problem-solving skills.
