  Hi Johan,

  OpenSesame doesn't have a pause button, but you could implement one quite easily. The most convenient way to do this depends on your experiment, but the following is one option.

  1. Disable 'Flush pending key presses (...)' in your trial_sequence.
  2. Add a new keyboard_response to the start of your trial_sequence. Disable 'Flush pending keypresses', set the timeout to 0, and set the allowed responses to p.
  3. Add a new sketchpad just after the keyboard_response. Add a text message like, 'The experiment is paused'. Set the run if statement for this sketchpad to [response] = p.

  Do you see the logic here? Basically, if you press 'p' somewhere just before a new trial starts, this will cause the pause sketchpad to be shown.

  Hopefully this will get you started!

  Cheers,
  Sebastiaan

  Okay Sebastiaan,
  I think I see how it could work. I will test it when I have some time and come back here to make a feedback.

  Cheers,

  Hello,
  So I tried a lot of thing running with this idea but i must be doing something wrong. i never had the good result.

  Most of the time, either I obtain a black screen (at the beginning of my sequence, when I put the two element here) and the experiment continues only if I press p, or I have a problem with the variable name. [response] does not exist in the sketchpad element...

  I tried with the two item at the beginning at the sequence, at the end, nothing changes.Perhaps you will have other idea or correction.

  
  
  or

  Hi Johan,

  I cannot really tell from your example what goes wrong, but the instructions in my previous post should work. Except for this, which I hadn't considered:

  I have a problem with the variable name. [response] does not exist in the sketchpad element...

  I forgot that the variable response does not exist at the beginning of the experiment, so the run-if statement [response] = p will cause an error. To fix this, you can simply add the following line to the top of your experiment's general script:

  set response None
  

  This will give response an initial value.

  To get you started, here's a working example of a pause button:

  Good luck!

  Yeah,
  I just tried your advice and it's working. The problem was due to the value of the [response] variable.

  Thanks !
