Place a time limit on a task?

You have reinforced the point that the duration meta command would be especially useful if it could kick in during the trial rather than between trials. I see your point about the variable length movies and the fact that you could have to create different styles for each. As cumbersome as that is, I don't see away around it for this particular application--not if you want to keep the trial durations constant with variable length movie files. Hmm.

In the posting 9/12/2007 it was mentioned that the next version of DirectRT would possibly allow the !meta function a higher priority such that it would be able to function not only between trials, but would be able to interrupt a trial after a given amount of time.

I am using DirectRT version 2008.1.0.13
Does anyone know if this version allows for this? From what I have tried, it does not appear to, but I could be missing something so any confirmation would be helpful.

My basic goal is to run open ended trials (rt:text) where participants have 15 seconds to enter a response. If they do not enter a response within that amount of time, I need the program to automatically proceed to the next trial after displaying the message "Please try to respond faster!" If there are any other suggestions as to how to accomplish this, that would be great as well.

Thank you for your help,
