Help with auditory equiprobable paradigm test
in OpenSesame
Hello all! Simply put: this is going to be an Oddball paradigm test that will play 3 sounds, a total of 30 times each, in a random order. The sounds are short .wav files files of a person speaking. Intertrial intervals will need to vary randomly between 700–1300 msec to prevent habituation to stimulus onset. So all in all the recording session should last ~8 minutes with a total of 90 trials.
This is a very simple program, however I'm still quite new to the world of programming and OpenSesame so I would be thankful for any help in getting started.
Thank you for your time!

Hi,
The step-by-step tutorial explains how to vary the values of a certain independent variable randomly. The example is with letters and pictures, but the same principle can be applied to sound files:
This previous post explains how to randomly vary the intertrial interval:
I attached an example script to help you get started. (You'll need to unzip it first.)
Hope this helps!
Cheers,
