[open] Tetris + secondary reaction time task

  Hi Diana,

  What exactly do you have in mind? Do you

  ... want participants to play a standalone video game and then have them switch back to the experiment after five minutes? In this case you could even use two separate computers, one running the experiment and another one running Tetris.

  or

  ... want the video game to be embedded in the experiment itself? In this case, you will really have to create a Python implementation of Tetris and run it from within OpenSesame. (That won't be easy.)

  Cheers,
  Sebastiaan

  Hi Sebastiaan, thank you for ur answer.
  Indeed I would want the second option because participants should perform on a secondary reaction time task while playing tetris so I guess if I want Open Sesame to record reaction times during game play...
  To make things worse: the game itself (whether they play successfully or not) should also be recorded...
  I am lucky to have a programmer who works with me, however, he is not familiar with open sesame so we agreed that I first find out what would be possible within the program.

  Do you see that this is 'do-able' within open sesame or do you think I should rely on something else?

  Thanks a lot for your help.

  Yes, it's certainly do-able for a programmer. Basically, you would just implement the game in Python, and then embed the Python script in OpenSesame. Since you can use PyGame from within OpenSesame, it might be worth taking one of the existing PyGame-based Tetris clones as a starting point:

  Oh wow That is a very good hint! Thank you so much for this !
  So I use the python script for tetris yay -- and then I program a secondary reaction time task along?
  Is it possible to have the game stopped after 5 minutes? And to "logfile" the results within th game? results as in how good or bad the participant performed?
  Again thank you so much for your help. Diana

  Yes, that would be the idea.

  Is it possible to have the game stopped after 5 minutes?

  Of course. You'll program the game yourself (or at least adapt it), so you can have it stop whenever you want and have it do whatever you like.

  And to "logfile" the results within th game? results as in how good or bad the participant performed?

  Yes, you can access the OpenSesame logfile in a script, as described here:

  Good luck!
