I am working on a project in which participants respond to different stimuli by pressing buttons on a keyboard - fairly simple stuff. However, as I have been testing and troubleshooting my experiment, one strange quirk is always constant. Every “response” must consist of two key presses in order to move on to the next event. So if I want to respond “2”, I would have to press the “2” key twice. I have tried everything I could think of to fix this issue to no avail. Does anyone have any suggestions for what may be causing this strange problem and how to fix it?
Thanks so much!
