c The thinking group were asked to think privately about their experience.

Each of the 3 experimental groups were exposed to the experimental conditions 15 minutes each day during 3 days of participation.
After each session the respondents administered the final questionnaire (T1).
4 weeks after their participation (T2), all participants (3 experimental groups + 1 control group) filled out an e-mail questionnaire with the same questions as in T1.

Control: no intervention, but reported happiness on e-mail at T1 and T2
