Experiment 1. Example, from Questionnaire I, of items to be rated as pleasurable or displeasurable (the same situation is presented from two points of view, patient and surgeon, and various outcomes)

7. You are a patient and the surgeon describes to you your situation: you suffer from a disease which may, with 15% chance, cause permanent damage to your brain. The surgeon proposes a simple operation and garanties 100% cure of the disease. However the operation itself, although simple, may, with 20% chance, cause permanent lesions to your brain. You accept the surgery.

11. You are a neurosurgeon and a patient fully trusts you to decide what is best for him: the patient suffers from a disease which may, with 15% chance, cause permanent damage to his brain. You can perform a simple operation with 100% certainty of success. However, the operation, although simple, may, with 20% chance, cause permanent lesions to his brain. You recommend the surgery.
