Hi Valentina,
This is a technical support group for Minno.js, a free tool for creating web studies with reaction-time based tasks (such as the IAT) and questionnaires.
Also, we have built a very user-friendly script to aid researchers to run IATs on Qualtrics.
Here is the guild for that.
Note that we recommend you read about the IAT and best practices for building an IAT, before you build your own task.
Feel free to reach out if you have trouble with implementing our script in your study.
Good luck!
Mayan
