<page welcome>
^^^^
Welcome to the Stroop Color Task.
</page>

<page page1>
Your task is to determine whether the word that appears on the screen is yellow, green, red or blue. Click on one of the four buttons that matches the color of the word (not the meaning of the word). You will have 20 trials. Try to respond as quickly as you can, because you will be timed.

This is the end. Thank you for your participation.
