As of December 18th, 2024, we searched for the original Study 1 materials and could not locate them. (The only exception is the Observational Coding Sheet, which was found and is provided here.) All co-authors were contacted, but none had the Study 1 materials. Therefore, the original Study 1 materials (other than what is already described in the manuscript) are considered lost. 

Also, please note: the "data dictionary" explaining the Study 1 data file is in the process of being created, as is the data analysis script.
