Using audio stimuli for IAT on Open Sesame
Hi! I am an Open Sesame/experiment-creating newbie. I'm using Open Sesame to create a 2 task experiment, the first of which is IAT. I have set-up one Loop, so far, using text as the stimuli. That's running fairly well, except for one thing, but I won't go into that now.
I have looked around this site for some hints on how to get audio - that I do have in my file pool in wav. files - into the a new loop. I have added a sampler into the sequence, thinking that would be where it's played from. I also have a sketchpad item, similar to what I used in the loop using/displaying text stimuli plus targets to categorize the stimuli with, but I wonder how that works with audio. I hope this sounds clear, and that someone might have some input into what I can do.
Thanks!

Hi,
That's simple: instead of the full path in the sampler item you create a partial part with a variable that is fed by the loop.
Thus, if you have e.g. /home/myaccount/experiment/sounds/sound1.wav as full path in your sampler item, you turn it into /home/myaccount/experiment/sounds/[sound].wav and add a column sound to your loop item with the values sound1, sound2 etc. (without the .wav ending).
Personally, I rarely work with the file pool but use only bare .opensesame scripts containing paths plus separate folders for pictures and sounds.
I think you can also put in __pool__/[sound].wav if you use the file pool, or even [sound].wav only. I do not have a pc around to test this right now...
Best,
Johannes
