The pre-task on-screen instructions ask: "IS THE PREVIOUS CARD THE SAME?" The test supervisor will read the task instructions from the script. To begin the task, the test supervisor or subject must press the "Enter" key.
A playing card is presented face up in the center of the screen. The subject must decide as each card is presented whether it is identical to the one just before. Therefore the first answer is always "No". If the face up card is identical to the one presented immediately before it, the subject should press the "Yes" key, if it is not the same they should press the "No" key. The card in the center will go to the back of the pack revealing the next card. As soon as it does the subject must decide whether or not it is the same as the card they have just seen.
The subject will practice until they reach the required number of responses, or until the practice period expires.
Then, on screen instructions for the real test are presented. The test supervisor or subject must press the "Enter" key to begin the real test.
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 "Yes" or "No" key before a card turns over. If they make a mistake they will hear an error sound.
