  Hi,

  Sure. What you could do is first create a variable that indicates whether or not a sound should be played on an error. You could do this with a simple inline_script at the start of your trial:

  import random
  if random.random() < .5:
      exp.set('sound_on_error', 1)
  else:
      exp.set('sound_on_error', 0)
  

  Next, you can use a run-if statement for you sampler that evaluates whether a response was incorrect and the sound_on_error variable is 1. Like so:

  [correct] = 0 and [sound_on_error] = 1
  

  Does that make sense?

  Cheers,
  Sebastiaan
