IAT and ST-IAT Truncated Results

[Ashleigh Yin]

Hello!

I am trying to run the IAT and ST-IAT in Qualtrics and I have managed to get it to work. However, when I try submitting a response and processing the data (as suggested on https://minnojs.github.io/blog/2020/07/10/running-the-st-iat-on-qualtrics/), the data seems to be truncated/incomplete. 

I have attached the edited csv files below for reference. 

Thank you for your assistance.

Best Regards,

Ashleigh

Dear Ashleigh,

Usually, when not all the data are saved in each Qualtrics IAT session, it is because Qualtrics limits the size of the data that can be saved in one question.  The solution for that is to use shorter image names, or to use quiat10.js for the IAT, with the argument shortData: true [by default it is false].  We don't have a similar feature for the ST-IAT extension yet. 

However, in your case, the stimuli seem very short, and both files are 9kb long. Qualtrics' limit is larger than that (around 20kb). 

I would recommend first testing whether you are able to successfully save and read the data using our example scripts. This will give you a sense whether the problem is with the specific scripts you created or a general problem with using our scripts in your Qualtrics account. If you don't get all the data using our example scripts, then perhaps your account has a smaller limit for response size. I am not sure how you can test that. Perhaps by creating an open-ended question in Qualtrics, and testing how much text you can type to the response. 

Yoav
