Token Search assesses your ability to retain and manipulate information in spatial working memory. To find all the tokens, you'll have to maintain and update an ongoing representation of previous searches, and develop a good strategy for searching.
A nice shiny token is hidden in one of the boxes that appear on the screen. Your task is to search the boxes until you find a token. When you do find one, remember where it was hidden, as a token will never be in the same box twice. Keep searching until a token has been found in every box.
What does Token Search measure?
Token Search relies most on your short-term memory, but strong reasoning will help a bit too.
Token Search in
the real world
Token Search can rely on strategies that carry over to the real world; who hasn't been frustrated when searching for an item among boxes, then forgetting which ones were already checked? A good night's sleep can help, too. One study found that performance on a test like Token Search plummeted in people deprived of sleep.
