BlockList duration

[mand...@towsonalumni.org]

Hello,

I am an e-prime noobie, but I've managed to make an experiment that runs and records all the trials and responses I want. I was just putting finishing touches on it, but have come across a stumbling block. The experiment examines the accuracy of the response on each trial, and for incorrect trials, the trial info is written to a List which is launched after all trials are run to rerun error trials. I'm still adjusting it so that incorrect responses continue to launch rerun trials until all trials are responded to correctly, forcing participants to answer all trials correctly before the experiment terminates. However, I also want the experiment to terminate, regardless of correct, incorrect, or no responses, FIVE MINUTES after the onset of the first trial. Essentially, I want the experiment to exit the BlockList after 1 cycle of the trial lists (filling in a rerun list as needed) OR after 300 seconds. Unfortunately it doesn't look as though I can specify both in my BlockList's properties pages, so I thought to make an InLine script to exit the list after 300 seconds, but I couldn't find anyone else who has tried to do this. It sounds simple enough, unless I'm overlooking something critical, so any advise would be appreciated.

Thanks!
