First the procedure.
Actually this is quite simple. One hooks subject to a skin conductance measuring device and puts the subject in front of a screen.
The subject has to press button and then 3 events occur while simultaneously the physiology is monitored.
First a blank screen appears. Then a picture is shown. This can be an emotional or a calm picture and then the screen goes blank again. After cooling down period this will repeatt itself (of course with different pictures who are randomly chosen from a large picturepool).
As you can see the baseline just before the picture goes up a little bit and that is completely normal because the subject is in anticipation of a picture and gets a little bit aroused.
Lets have a look at what the mean physiologiacl trace looks like for a single subject.
