Two sets of seven pictures each were taken for preference ranking. The subjects for the first set were 32 (16 male, 16 female) persons aged between 19 and 46 years (average: 25.5 years). The second set of pictures was ranked by 63 persons (33 male, 29female, 1 other) with an average age of 29.1 years (ranging from 19-70). 73 of the probands were recruited at the campus of the University of Göttingen, Germany and conducted the test in a controlled laboratory environment. The other 22 persons conducted the internet-based test somewhere else. The first set of pictures was tested a second time during the course of a graduate spring school by 16 participants (age range from 26 to 40 years, mean 31.1 years; 12 female, 4 male).
