Hi Jarvis,

Thanks SO much for your speedy response and help with this! I was thinking something like that might work but the issue seems to be that I actually need a multiple response item to be on the screen for the 3 minutes before the sound goes off and automatically proceeds to the next screen (I'll give them instructions beforehand to stop talking after the beep). I tried creating a sound clip that's 3 minutes of silence and then a 1 second beep and put it in the background of the MR question, but for some reason not only does the sound beep go off but medialab seems to beep as well with a pop up alerting the participant that time is up for the question you have to click the continue button (which is still on the screen despite the duration parameter) to continue. I think that's just going to be a bit too startling and confusing for participants...would you happen to know of any way around that?
Thanks again SO much for your help!
