For my current thesis I had measurements of EEG activity from 24 mostly student subjects. The intention was to capture moments of fear or anxiousness which are induced only using audio effects. What turned out early that it's pretty hard to do. How can you arouse anxiousness to people that have different concepts of what's frightening and what's not? How can you point out the exact moment, when that feeling occurred? Are just audio inputs enough for someone to experience real danger?
