| Variant 1 for the experimental and control group 1: Experimental paradigm : The secretary-problem (sp) in the basic version (see Seale & Rapoport, 1997) with the variation that the subjects receive a certain amount of points, depending on whether they have chosen the best, second best or third best, etc. applicant. The amount of points varies depending on the selected absolute rank (cf. Bearden, Rapoport & Murphy, 2006). The points will be converted to a certain amount of money in the end. Evaluated will be: Performance: the average amount of points, that is, the average absolute rank of the chosen candidate at T1 (baseline) and at T2 (after a ¾ year or after a short-term therapy) Search length: the average number of applicants considered at T1 (baseline) and at T2 (after a ¾ year or after a short-term therapy) Relative rank: the average relative rank selected at T1 (baseline) and at T2 (after a ¾ year or after a short-term therapy) Decision rules: the selected thresholds for the decisions of the subjects, ie. How many applicants will be let go by until a decision is made at T1 (baseline) and at T2 (after a ¾ year or after a short-term therapy) Variant 2 for the experimental and control group 2: complex secretary-problem: two rank informations (two attributes) must be observed (see Bearden et al., 2005) Evaluated will be: Performance: the average amount of points, that is, the average absolute ranks of the chosen candidate at T1 (baseline) Search length: the average number of applicants considered at T1 (baseline) Relative rank: the average relative ranks selected at T1 (baseline) Variant 3 for the experimental and control group 2: The secretary problem: punishment condition: Variation with respect to the obtained message, if not the best candidate is chosen -> "What a shame! You only have elected the xxx best. You just achieve xx points out of the possible 40 points” Evaluated will be: Performance: the average amount of points, that is, the average ab | — |
