Dawn, Currently, there is a 500 ms delay at the start of each trial while the fixation is displayed. Participants have 800 ms to make a response before the response collection times out. There is also a 400 ms delay on practice trials when feedback is given.
In the next version of PEBL (0.14, which I will release hopefully in the next couple days), these parameters will be controllable via a dialog in the launcher.
