Summary

The study tries to identify whether positive expectations, induced with a placebo nasal-spray, have short- and longterm effects on participant's mood.

Detailed description

Healthy volunteers are informed that a new application method for a well-known antidepressant would be tested. They will randomly be assigned to the experimental group (taking the antidepressant which is in fact an active placebo) or the control group (not taking a placebo). Then participants watch a well established film sequence to induce sadness. Sadness is assessed before and after receiving the nasal spray and watching the film sequence. In the seven consecutive days the participant's mood is assessed each day, only the experimental group is taking the placebo each day. Afterwards participants will watch another sad film sequence and sadness will be assessed before and afterwards.
