I am designing an experiment in which participants must press buttons to trigger sounds. Ideally, I would like a 20-50ms window between the button press and the sound to better give the illusion of auditory feedback. Is this possible in Superlab?

Best wishes,

Attached is a small example of such an experiment.

There are two necessities for this design:

1. A block that loops until its associated trial stops being presented.

2. Feedback actions that present inter-stimulus interval and audio events, like so:





Following this example, as long as all buttons are designated as correct responses, there will always be an interval between pressing and sound.

In rereading your post, I've realized that the looping component of my solution may be irrelevant.

Also, I'm not sure if you require a random time interval between 20 - 50ms to be used or rather just one that is fixed.

Perhaps you can clarify these details or post an experiment that more specifically demonstrates your desired design.
