Seventy-three students and staff ages 18-35 were recruited from the Universities of
Hohenheim and Stuttgart to participate in the experiment. The recruitment was completed
by placing poster advertisements in different locations in both universities, such as libraries
and scientific institutes. Flyers were distributed at the end of lectures, on cafeteria tables,
and to individuals. Participation in a prize draw of five €20 gift certificates was offered (see
Appendix B for flyer and poster details). Individuals made an appointment through a Doodle
link and were contacted via e-mail to ensure that the inclusion criteria were met and none of
the exclusion criteria were met (see Table 4).
