Yes, I would use the same approach to start with. Hormonal
levels are measurable parts of our systems and it shouldn't be
TOO difficult to come up with moods via various combinations and
approachable metaphors to work with.
I suspect if you look around a little, somebody's done at least
the hormonal levels --> mood connections for some of them.
Look at music. Advertising made a science out of "emotional
appeals", as does movies and music is a HUGE PART of emotional
manipulation - all nicely categorized.
