What is a "sexual arousal assessment"?
You will be asked to watch a series of commercially available film clips, some of which will be sexually explicit, while we monitor your body's sexual arousal. In between the film clips, you will complete a short questionnaire.
Measuring sexual arousal is done with an probe called a vaginal photoplethysmograph or Geer gauge. To see a photo of the probe, click here. The probe is about the size of a tampon and is made of acrylic plastic. You would insert this probe into your vagina and it would remain there while you watch the film clips. All this is done in a private testing room where you communicate with the experimenter via intercom. To see a picture of the testing room, click here or here.
