Keypresses not properly registered in the experiment (appearing within the .log-file not the .csv)

Hello @lara_k

Look here to see what ‘duration’ means in this context: Measuring key lift time relative to stimulus onset. However, I am not sure that this will solve your problems. You want to register all RTs, not just most of them.

Have you tried addressing any of the issues I mentioned above?

  1. Saving information to the disk at a time-critical moment;
  2. using win.flip even though you shouldn’t,
  3. storing information about the time yourself when PsychoPy can do this for you?

Best wishes Jens
