You can find the procedure video at https://youtu.be/SSCP00GXF5U if you are unable to view it through the OSF page
In our data collection procedure video the experimenter does not explicitly state not to speak about the study with anyone however the following statement is included in the debriefing and is in the script which will be verbally read to all participants;
“We ask that you do not discuss the details of the experiment to other people who might participate in this study. Please understand that if you knew the details of the experiment ahead of time, you may have responded differently to the tasks. Thank you for helping us preserve the integrity of our work, and thank for participating in the experiment today!”
