All versions involve the presentation of visual images of different shapes to the examinee. The examinee is to determine which underlying concept is presented by the image and choose a number from 1 to 4 to identify the concept. For example, the examinee may choose the number corresponding to the number of items in the image, the proportion of the image that is drawn continuously, etc. The examinee is given feedback after each choice to indicate if he or she was correct in their decision. By a process of utilizing this feedback to monitor performance, the examinee then learns the concepts. The number of errors is used to determine the overall performance.
