I’m trying to show a picture for 3 seconds then a 1s blank, and I want participants to name the picture asap.
The tricky part is that I want the picture to stay on the screen for 500ms after a response is given. If I use a button box, the picture will disappear immediately when a response is given; if I use the built-in mic, the picture will stay there for the whole 3 seconds.
I also want the picture routine to finish even if a response is given. For example, if a response is given at 700ms (RT=700), the participant should be able to see the picture for 700+500=1200ms, then 3000-1200=1800ms blank, and then 1s blank.
Is this doable?
