We are trying to create a Stroop Task and want participants to press the correct key before proceeding to the next trial. Following the manual, we created an incorrect.txt file and put it in the session folder. The program ran smoothly.

We would like to know if it's possible for the user to respond with the correct response, but without the 'X' that appears. We tried to leave the forth value in the incorrect.txt blank but it did not work. Any suggestions?

Thank you very much.
