Welcome, Doctor.
In this study, you will be acting as a medical professional diagnosing patient x-rays. On each trial, you will see a simplified x-ray image represented by a grid of black and white squares.
Your task is to decide whether the patient has a tumor (Category A) or is healthy (Category B).
You will receive feedback if you make an error. Try to be as accurate as possible. The experiment consists of one block of 96 trials.
