[solved] How to create different feedback delay for each response key?

  Hi Noam,

  Yes, that's certainly possible! To make the response-flash interval depending on the given response:

  Firstly, place an inline_script item between the keyboard_response item and the flash:

  

  Secondly, place the following Python code in its Run phase tab (see comments for more information):

  # Determine the delay between response and feedback item
  # depending on the given response:
  
  # To determine the given response, we use the built-in OpenSesame
  # function 'self.get()'. See also:
  # http://osdoc.cogsci.nl/python-inline-code/experiment-functions/#experiment.get
  
  # If keyboard responses that do NOT appear in the if-statements below ARE
  # allowed to be given, first make sure your experiment doesn't crash 
  # if a different response is given. You can do this by giving 
  # the variable 'delay' (which we'll use to pause the 
  # experiment) a starting value:
  delay = 0
  
  # If a certain response is given ...
  if self.get("response") == "a":
      # ... declare the corresponding delay in ms:
      delay = 300
  if self.get("response") == "b":
      delay = 600
  
      # Etc. for the other responses
  
  
  # Set the response for future use in the GUI (e.g. for
  # your logger item) by using the 'exp.set()' function.
  # See also:
  # http://osdoc.cogsci.nl/python-inline-code/experiment-functions/#experiment.set
  
  exp.set("delay", delay)
  
  # Pause your experiment for the desired delay by using the built-in OpenSesame
  # function 'sleep()'. See also:
  # http://osdoc.cogsci.nl/python-inline-code/experiment-functions/#experiment.sleep
  self.sleep(delay)
  

  Does this answer your question?

  Best wishes,
