  Hi Erwin.
  I'm glad to read your petition because I'm working on it right now and trying to built the adjusting amount procedure on OpenSesame, as well. Did you get any answer about it?

  Try this:

  RespKeys = keyboard(keylist = ['x','m']) # your responses on the keyboard
  
  var.low=50 #starting value
  var.high=100 #starting value
  
  for i in [2,4,8,16,32]:
      Stim=canvas()
      Stim.text('Please select x for: '+str(var.low) + '  or select m for: ' + str(var.high)  )
      Stim.show()
      Resp, Resp_t = RespKeys.get_key()
      log.write_vars()
  
      if Resp=='x':
          var.low=var.low - 50/i
      elif Resp=='m':
          var.low=var.low + 50/i

  Thank you, Stephan.
  Please, let me interpret your code to see if I'm understanding. – Is the standard amount 100 and the i values (2,4,8,16,32) are the different delays?

  Does this code have to be written into the loop or sequence tool? – I am new in OpenSesame and learning about it.

  Thank you so much in advance for your help!
  Best regards,

  Hi Gisel,

  in a new experiment. make a sequence. Put the inline_script and a logger item behind.
  That's it.
  Try the code if it fits for your porpuse. Then adopt it as you need it.

  The standard amount 100 keeps always the same as in the picture by Erwin.
  The lower amount changes. That's what you need the i values for. See the calculation for var.low at the end.

  Enjoy
  Stephan
