Below I provide a Vignette for conducting analyses similar to those we did in the Unobtrusive Measure of TMS paper. Using this, you should be able to take text that has been coded into 2 or more categories and create a dictionary of terms that could be plugged into LIWC.
The formatting is sometimes a bit strange when I embed the vignette so you can see the vignette by clicking here. If you’d like to download the RMarkdown file, you can find it here: Unob_Vignette
I hope this can be of use to someone. Please let me know at jkush@umassd.edu if you have any questions or suggestions! Special thanks to Saheer Shaik for his assistance.
