Hi,

I have a couple of questions

1) Is it possible to randomize a trial's duration (either using /trialduration or /response = timeout ())? I want to try and have my intertrial interval randomly vary between 500ms and 400ms on any given trial.

2) I want a particular (mouse-click) response to give participants a 'reward' feedback trial on 80% of trials, while presenting the same mouse-click with a different 'no-reward' feedback trial on the other 20%. I'm not sure how to go about building in these percentages into the branch trials. What's the best way to do this?

Thanks,

Jay
