Group: Forum Members Posts: 18, Visits: 27	Hi Dave, In my current study, I have set up some images appearing in a random order. The participant is required to count the number of animals on screen and enter a value. I was able to write the code for this and it works. However, I am having trouble adding audio to the trials. At the display of every image, I want two audio files to be played (both included in the folder attached below) - first "what_card.wav" and then "CanUCount.wav". My issue is that when I try to make the </sound> category, I am given an error about double quotes, even though I have double quotes in my syntax. Could you please help me out? https://drive.google.com/drive/folders/1zUe3Rj-OsPwauF1esQQbyrpwgad4QeEa?usp=share_link

These are simply the wrong quote characters (don't copy & paste from word processors or the like). You need to use plain double-quotes, i.e. <sound whats_card> / items = ("what_card.wav") / playthrough = true </sound>

You display <sound> stimuli just like any other type of stimulus, be it <text>, <picture>, <shape> or <video>. Add the sound stimulus to a <trial>'s /stimulustimes or -frames, at the time you want it played.

Add the sound stimulus to a <trial>'s /stimulustimes or -frames, at the time you want it played. It's not entirely clear when, exactly, you want those audios played, but I'm guessing you want something like this: <sound whats_card> / items = ("what_card.wav") / playthrough = true </sound> <sound can_u_count> / items = ("CanUCount.wav") / playthrough = true </sound> being the two audios, and the trial playing those back one after the other before allowing the subject to continue. <trial showpicture> / stimulustimes = [0=stimuli_display, whats_card; 2000=can_u_count; 5000=continue] / validresponse = (continue) </trial> Change the timings as needed if you want a longer or shorter pause between the two sounds.
