Hi,

I am trying to use a response window whereby after the participant must respond while a stimulus is displayed for 133ms (a red !). If the participant responds during this time, then I would like the trial to terminate and go to the next trial. However, if they do not respond within that duration of 133ms (while the red ! is displayed), then I would like the next stimulus in the trial to be presented (a black !) until a response is made, then proceed to the next trial. All of the trials in the experiment need to be random, so I cannot just tell the program to jump to a specific trial. Do you have any ideas of how I could do this?

Thanks!
