We are currently running an online study where we look at the influence of various factors while identifying threatening stimuli in the environment. The experiment is carried out in English and German and tries to identify difference between police officers, martial artists and civilians without any fighting experience.
So if you have 30 minutes of your time left (without getting distracted), please take part in the experiment.
The English version can be found here:
It would be great if you can help. Thank you!
