A method for testing a working memory and fluid reasoning of a subject includes the step of sequentially presenting to a subject a first plurality of images, wherein each image is positioned in a different sector of a display device. The first plurality of images totals one fewer than a total number of sectors. Next the subject is simultaneously presented with a second plurality of images. One of the second plurality of images bears an analogous relationship to the first plurality of images. The subject is then asked to select an analogous image from the second plurality of images.
