Hi,

I'm currently working on a task, I'm stuck with a problem.
Indeed I have set the spacebar (57) as the responsekey and when I push on it to test my task nothing happen, it's not received neither recorded.

Could you help me to fix this issue ?

Best,

By default, the trial will not begin accepting responses until the last stimulus has been show (here: clearscreen at 1250ms). That is also the time where the trial effectively ends per your /trialduration. There is no time to submit any response. You need to use /beginresponsetime and, depending on how you want the trial to behave after having received a response, /responseinterrupt.
