[solved] Logging Response Times to Button Click

  Hi Chris,

  Response times are automatically determined only for variables collected with response items (such as a keyboard_response item or a mouse_item). If you want to determine response times for other response variables (such as input from a form_base item), you will first have to calculate and set it yourself in an inline_script item. After setting the new variable (by using the exp.set() function described in the link below) it will automatically be logged by the logger item.

  More specifically, you can calculate and set the response times yourself by appending an inline_script item immediately after a given form item, and put something like the following code in its Run phase tab:

  # Determine the starting time of the form item:
  starting_time = self.get("time_my_form")
  
  # Determine the current time:
  current_time = self.time()
  
  # The time it took to complete the form base is the 
  # difference score between the two:
  my_rt = current_time - starting_time
  
  # Set the new variable for future use in the
  # GUI (notably, the logger item):
  exp.set("my_rt", my_rt)
  

  Does this help?

  Best wishes,

  Lotje

  Hi Lotje,

  Is there any other way to get response time for button clicks?

  I have tried the inline script you provide but it did not work.

  Nevermind, apparently already resolved in #680.
