[solved] How to get a pause mixed in with 120 trials

  Hi,

  What I usually do is add a sketchpad called 'pause' to the sequence item that is run via your loop (let's call it 'trial_sequence'). Write some text en the sketchpad (e.g. "Break! Press any key to continue") and set it's duration to 'keypress'.

  Now, in trial_sequence, set the 'Run if' statement to [count_trial_sequence]%60 = 59. This will make the pause sketchpad run only when the remainder of the number of trial_sequence's runs divided by 60 is 59. I.e.: once every 60 trials.

  Good luck!

  Hi Edwin

  That worked flawlessly. Thank you for your help and your fast reply.

  Best, Simon.

  Hi all,

  I react to this topic in particular because I have nearly the same issue as SimonDP except that the formula doesn't seem to work for me. I have 240 trials, so I'd like my break to happen after the 120th trial. I created a sketchpad as explained and tried to change the "run if" statement on my sequence for [count_trial_sequence]%120 = 119 on the same basis as yours. What did I do wrong ?

  
  

  Thank you in advance,

  Ire

  Hi @Irekaeru,

  Have a look at your data log and identify the variable that counts the trial number in your experiment. If your sequence is not called "trial_sequence", then "count_trial_sequence" does not exist. Having a look at your data log will help you determine a variable that does increment with every trial. Note that there multiple "count_" variables and that you could use that corresponding to the trial sequence but also to any object contained in your sequence.

  Good luck!

  Fabrice.
