Minimum trial duration

socialpsych — Wed, 29 Mar 2017 02:14:12 GMT

I'd like to present some text on the screen for a minimum duration of 3 minutes, but longer if no response has been made (I want my participants to take a break of at least 3 minutes but longer if they need to; if the experimenter presses a key during the first 3 minutes to indicate the participant is ready, the trial should wait until 3 minutes have elapsed before terminating, but if not it should wait for the response before terminating).

I can see a few ways to set a maximum duration but no obvious way to set a minimum duration. Is there an easy way to do this that I'm missing?

Thanks!

Yes, you can do the following:

<trial wait>
/ stimulustimes = [0=waittext; 180000=waittext]
/ beginresponsetime = 0
/ responseinterrupt = frames
/ validresponse = (57)
</trial>
