Hi everyone,
I hope you are all safe and sound.

Unfortunately I have a problem with my data output from Inquisit 5, and I am hoping one of you might shed some light on this. I am not a particularly experienced Inquisit user and am working with inherited code, so I will do my best to explain, but please ask if you have any questions.

Our experiment displays 6 videos to participants, and after each video, it asks them 3 questions.

The output for this is shown above - the stimulusitem1 column contains first the name of the video, then the full text of each of the three questions in the order they were asked. This allows us to marry the response to the specific question, and all three questions to the relevant video.

We recently wanted to add two more questions to the experiment, and did some relatively simple modifications to the code to achieve this. Although we tested it, we did not catch a key difference between the two DAT files - the full question is no longer listed in stimulusitem1, nor does each question have a unique stimulusnumber1. Instead, the output now looks like this:


Unfortunately, the new questions are about empathy, and so we cannot simply average all 5 questions together.

I have looked at the code, but I cannot determine what could cause a change like this. I have also researched this on these forums, and can confirm (for example) that absolutely no changes were made to the <data> section between files. It appears to me that the only changes were the addition of new questions to a pre-existing "questions" section, and a re-arranging of the trial order to suit this. I am absolutely baffled as to what has caused this change in the output.

Thus, I have two questions:

1. What has caused the change in the data output? I have attached both code files to this post, and I am hoping someone might shed some light on this mystery and how I might fix it.

2. Is there any way I can use the data I have to determine which question is which in the second output? I was thinking, for example, that we know the time and date of the study - is this what is used to seed the RNG? If so, is there any way to determine what the order was after the fact? I realise that this is a long shot, but with current circumstances, it may be a while before we can gather any more data, so I would be quite upset to lose this lot.

Thanks very much for any answers you can give - please let me know if there is any more information I can provide.
