the n-back task

The n-back task is a mental exercise that challenges your working memory. You are shown a sequence of items (like words, numbers, or pictures) and must identify when the current item matches the one from 'n' steps earlier. For example, in a 2-back task, you say if the current item is the same as the one two steps before. This requires keeping track and updating information in your mind, helping to improve your attention and memory skills through practice. The difficulty increases as 'n' gets larger, making the task more challenging.
