The pre-task on-screen instructions ask: "Have you seen this card before in this task?"
To begin the task, the test supervisor or subject must press the "Enter" key. A playing card is presented in the center of the screen. As soon as it does the subject must decide whether or not the same card has been seen before in this task. Therefore the first answer is always "No".
Each time a card is revealed, the subject must decide whether they have been shown that card before in this task and respond by pressing the "Yes" or "No" key. The subject should be encouraged to work as quickly as they can and be as accurate as they can. For example, they should try not to press either the "Yes" or the "No" key before a card turns over, and they should try and remember all the cards that are presented in this task. If they make a mistake they will hear an error sound.
