  First of all: Thank you for your great work! I'm just starting with OpenSesame, but find it really intuituve and manageable!

  I have the same issue (currently working on a Go/No-Go Association Test). The correct_* variables are empty (?) or 0, for trials where timeout would be correct.

  btw: it works with enabled auto response

  Hi guys,

  I have a faint recollection of answering the exact same question sometime earlier, but I can't find the thread anymore. Anyway, what you could do is add a little bit of inline scripting. Let's assume you have a variable defined in your loop (let's call it go), and this variable is 1 on a Go trial and 0 on a NoGo trial. Place the following bit of code in an inline_script item, directly following the keyboard_response item in which you collect a response:

  if self.get("go") == 1 and self.get("response") != "None":
      exp.set("correct", 1)
  elif self.get("go") == 0 and self.get("response") == "None":
      exp.set("correct", 1)
  else:
      exp.set("correct", 0)
  

  Make sure to leave the "correct response" field of the keyboard_response item empty.

  Good luck!

  Hi,
  I am a beginner and I really need a more explicit advice.
  I inserted a in-line script, copied and pasted this lines of code (pepare, run or both?). What should I mention in the case "Run if" on the item feedback?
  best,
  Xavier

  I am now realizing that you did not include a feedback, which is my case. Thus, what I want is a feedback indicated both misses (partipicants failed to press the key when they had to) and false alarms (they erroneously pressed the key).
  Any idea how to do this?

  I found the response: "timeout" should be coded "None". Now, everything is fine.
  Very lovely program by the way
