  Hi Laura,

  First of all, I recommend you doing the beginner's tutorial: https://osdoc.cogsci.nl/3.2/tutorials/beginner/

  This will already help to make clear how Opensesame works in general.

  For your specific example, I am not sure whether you can achieve what you want to, using only the loop table and standard items. I would use inline_scripts instead.

  If I understood correctly, you have 3 variables.

  Emotion (5 levels) x target side (2) x cue validity (2), right?

  So to make it completely counterbalanced (and have the same likelihood of invalid and valid trials at each location), you would need 100 trials.

  
  

  import random
  emotions = ['emo1','emo2','emo3','emo4','emo5']
  cue_pos = ['left', 'right']
  cue_valid = [0,0,0,1,1,1,1,1,1,1] # 0 represents invalid, 1 is valid
  
  trials = []
  
  for em in emotions:
     for pos in cue_pos:
        for va in cue_valid:
           trials.append([em,pos,va])
  
  # shuffle everything so that you have it randomized
  random.shuffle(trials)
  
  # next you have to assign the target position based on the cue position
  # and the cue validity
  # also you need to select a random emotion from the emotion category, e.g.
  # using random.choice()
  
  

  This should get you started. Let us know if you need help.
