The Task

In this exercise, items such as numbers and letters are presented one after another. Your client will be instructed to respond each time an item appears after a certain number of other items, such as “2 numbers back”. Your client will be told how many items back they must remember.


For example, if your client is asked to respond when a number was presented 2 items back, your client would respond in this sequence to those numbers in bold here: 9 5 6 5 2 7 2. The 5 is the second and the fourth item presented, so when your client sees the 5 as the fourth item, it was also presented two items previous, or “2-back”. When your client sees the 2 as the seventh item, it was also presented to them  “2-back” during the 5th item.


What It Trains

Your client will need to continuously update their short-term working memory in this task. As the length of the n-back increases, your client will have to remember the items for longer periods of time.


You can modify the type of item (Colors, Numbers, Symbols, or Letters), the number of items (10 to 120), the type of task (N=0 to N=5), the presentation and answer time (10s to 1s, or Unlimited), the time between the stimuli (10s to 0s, or Unlimited), and the number of items previously showed (5 to none).
