This year we have worked quite intense on developing language free or at least language minimized questions about YOUR (vacation) experience. We have presented it recently at a conference.
In a nutshell: some concepts like challenge, time and rejuvenation as well as complex emotions like pride and triumph are relatviely easy to express non-verbally and seem to be universally understood. Other concepts showed quite a spread in how people interpreted them, sometimes due to age effects, sometimes due to cultural aspects. Our work will continue i.e. data gathering.
