Thank you for your kind reply. I have a follow up question.
In order to have it only proceed when the participants press the right key, I have changed EndAcrion to None:
QRTLib.setConfig(“StroopItem”, “EndAction”, “NONE”);
According to the tutorial, in this case the program will only record the key press but won’t progress to next one until “it is told to do so expressly”. So I think I need to tell the program to do it when the answer is correct. I wonder how to do this. I tried to added the this.proceed() to it, but it doesn’t seem working.
Thank you.
