  Hi Rampriya,

  This older thread might be helpful:

  • http://forum.cogsci.nl/index.php?p=/discussion/363/solved-double-space-bar

  If you want to calculate and log the absolute RT and the relative RT between the response, you can add and subtract the timestamps within the while True loop of that script. The are quite some threads around on the forum that might help you with that.

  Best,
  Laurent

  Hi,

  Is this code what you want?

  
  kb = keyboard()
  
  # first response
  start_time1 = clock.time()
  k1,t1 = kb.get_key()
  if k1 != None: 
      response_time1 = t1-start_time1
  k2,t2 = kb.get_key(timeout=1600)
  if k2 != None:
      response_time2 = t2-t1
  else:
      response_time2 = None

  Please don't discuss the same issues in two separate threads. It will make the forum very messy!
