I am a user of Direct RT and am trying to do the following using the audio response options. On some trials I want participants to say a response word out loud to be recorded. I know how to program this. On other trials, however, I want them to not say anything. On these latter trials, I would like to be able to detect if they said something by mistake and then give them feedback (presumably using the jump function) that they weren't supposed to say anything. Can you tell me how to do this? Any support is greatly appreciated.
