Hi Meredith,
I will assume that your question is about our the
Free Web IAT that we currently support.
When defining your IAT, you can change font color and size of the title of each category and attribute, of the items of each category and attribute, and of the instructions. To learn how to change those definitions read the "
How we define the IAT" section in our guide for creating your IAT.
The code snippet in that post does not include the instructions argument. You can see them in the definition of the default IAT parameters -- the definition of iatObj in the
IAT extension. There are separate arguments for instructions in the touch version and the keyboard version. The instructions are <p> html elements, which support the modification of the font (size and color).
As explained in the post, please note that "Although our IAT script supports touch devices, the IAT does not detect automatically whether the participant is using a touch device (e.g., mobile). Therefore, if you want your participants to run the IAT on a mobile device or a tablet, it might be best to create an IAT version specifically for those participants (in your script, set isTouch:true in the IAT parameters)."
All the best,
Yoav
