Millisecond Forums

I'm working on a task in which a video will play continuously in the background and trials will be defined as specified windows of time in which a "driving hazard" is on screen. I would like to record responses continuously throughout the task, so that if a person presses the button multiple times when a hazard is on screen, all of those latencies are recorded. I think I have that part worked out - however, I would also like to display a feedback image each time they press the button (the picture will be the same each time). I've tried using the /errormessage, /correctmessage, and /responsemessage functions of trial, but I have only been able to get it to display a message once per trial. Is there a way to display response feedback multiple times during a trial and simultaneously record the latencies of each button press?

Thanks!
