Problem with Stimlist - DRT shows only first item (case 427)

[ksavani]

Hi, I am having trouble with a stimlist. I have used the "&" function to call the stimlist items sequentially, but DRT only displays the first item in each stimlist repeatedly, without going down the list.

The file Shapes1.csv calls the GoodDecision.txt stimlist whenever the participant selects "Bounce" as the response, and calls the BadDecision.txt stimlist whenever the participant selects "Throw" as the response. The stimlists include a combination of outcomes "Correct" and "Wrong" but in different proportions. However, DRT only displayed the first outcome repeatedly.

Can you please tell me what I am doing wrong? I have until May 25 to run this study before the semester ends, so I would be greatly indebted if you could look over this in the next couple days.

Thanks a ton,
Krishna

I found the solution - I did not realize that the "&" prefix assigns items to variables calling stimlists in advance.

Were you able to find a work around? e.g., putting both outcomes in the same stim file but in varying proportions (depending on condition) and the drawing from that list randomly? Or something along those lines?
