I’m trying to set up an experiment that involves a movie clip being played continuously. While the movie is playing, the participant presses a key on the keyboard. Upon keypress, a tone is provided as feedback. I would like the tone delivered NOT instantaneously, but at some time delay.
So far, in attempt to add the delay, I inserted an ISI as a feedback to the key press, and the tone as a feedback of the ISI. I was not able to get the tone to be delivered. Without the ISI, the tone is delivered instantaneously.
As a side note, I think my setup would work with non-movie stimuli.
Hope someone can help!
