using a coroutine
I'm trying to use the coroutine item for the first time but I don't seem to achieve what I have in mind. Basically, I want to show a stimulus for 350ms ("probe" in the pic I attached) then a fixation for 5000ms while participants can respond with the mouse any time between the presentation of the stimulus and the end of the fixation (i.e., any time within that 5350ms interval). I attach a pic of how I set this up but it doesn't work as I had imagined. The problem is that "fixation3" does not stay up for 5000ms and I think the same happens for the "probe" (i.e., not staying up for 350ms). I've read that sketchpads and feedback items don't have an end time so I'm not sure if I can manage what I want with a coroutine. Any help?
PS I've done it in another way (i.e., having two mouse inputs and adding the time) based on another thread in the forum but I was hoping that it would have been more straightforward with co-routines.
