Response grid

Hello, I m a beginner...
I need to create a "response grid" (eg, where one click on the letters in the right order). For exemple it is displayed F.S.X.M, have to click in the right order (F.S.X.M) on a grid where several letters are displayed.
I imported a "touch response" but I don't know how to make it work.

Does anyone has some advice to help me? or redirect me to a website

Thank you


  • Hi Chris,

    Maybe this tutorial is something for you:



  • Hi Chris,

    if with "touch response", you mean the TouchScreenButtonBox device, then you can find the documentation of it here:

    Basically, you can create all your letter stimuli, give them a position, and then add them to the TouchScreenButtonBox object. When you then call the wait() method on this object, it will wait until any of the letters will be pressed and return which one has been pressed. You can repeat this then as often as necessary and keep track of the sequence a participant presses the touch buttons.

    I hope this helps. Let me know if you have any further questions.


  • Thank you both,
