This is a computerised task, which will take approximately 10 min of your time.
Imagine that you are a doctor.
In this experiment, you will receive information about a patient who is allergic to some but not all foods. On each trial, you will see which foods the patient has eaten and after that you will be told whether the patient showed an allergic reaction. The patient always eats the same portion of each type of food.
Sometimes the patient eats two types of food within the same meal and thus two portions (one portion of each type of food). If this happens and the patient has an allergic reaction, then you do not know which of the two foods was responsible for the allergic reaction. You nevertheless have to determine for every single food to what extent it causes an allergic reaction in your patient.
First, you will see 50 trials. Every trial stands for a separate moment on which the patient ate a meal and the allergic reaction was measured. At the end of the experiment, you will have to judge for each food separately how likely it is to cause an allergic reaction in the patient.
Each of the 50 trials that make up this computerised task will consist of three slides. On the first, you will see the food eaten, followed on the next slide by information regarding the occurrence of an allergy. The third slide is a blank slide which is briefly presented before the next trial to help you assimilate the information. Progression through the trials is automatic. Please do not touch the keyboard once the trials have begun.

You have finished viewing the patient information.
The doctor now needs to make a judgment as to which foods are most likely to cause an allergy.
In the next series of slides you will be shown each of the foods.
Please rate the likelihood that each food will cause an allergic reaction in the patient on a scale from 0 to 100 where zero indicates that the food will definitely not cause an allergy and 100 indicates that it definitely will.
