[open] question about ways to give feedbacks

  Hi,

  Although I am not quite sure what you mean, I think you want to explore inline scripting and the random module. A code snippet, as an example:

  # import the random module, so we can use it
  import random
  
  # get response (from previous keyboard_response)
  response = self.get("response")
  
  # check if the response was '1'
  if response == '1':
      # generate a random number between 0 and 1
      r = random.random()
      # check if the random number if lower than 0.8
      # (this will happen in 80% of the cases)
      if r < 0.8:
          # award one point
          points = 1
      # if the reward between 0.8 and 0.95
      elif r < 0.95:
          points = 2
      # if the reward was between 0.95 and 1
      else:
          points = 3
  
  # set the points variable, so you can use it in a feedback item
  exp.set("points", points)
  

  Place this script in the Run phase of an inline_script item placed directly after a keyboard_response item. Place a feedback item directly after it, in which you show the text [points].

  I hope this example and the links will set you off in the right direction. You could also try to do some tutorials, to get acquainted with OpenSesame first.

  Good luck!

  @oritnaf: it would help if you could you define your question and rules a little more precise ? it is quite hard to get what you want to do.

  As Edwin pointed out you can the use the random class provided by Python and then decide on rules with if / else / elif statements. To help you with that one should know what your rules are and how you want to provide feedback.
