Sample stimuli used in this study. Images were reproduced from the Japanese Society of Radiological Technology Database (Shiraishi et al., 2000). Top: in the training sessions, a pair of normal and abnormal images were presented. Participants clicked on the image that was abnormal. Following their response, a red frame indicated which image was abnormal. Participants then clicked on where they thought the tumor was. This was followed by a feedback screen that indicated the location of the tumor. Bottom: three formats used in the testing sessions
