Essentially, we viewed this test as a potentially solid measure of map reading abilities. Twelve lettered sections (from A to L) are divided by white lines on each map and the test-takers are asked to identify the section of the map in which the photographed section can be found. The scale of the photographs is always 10 times larger than that of the map. On each page, a military map of various locations in the United States and four aerial photographs are presented. This part of the test measures the ability to locate on a map the places shown in photographs. However, to keep testing time reasonable, we used only the second part of this test as it produced the best predictive validity for successful completion of bomber pilot training in the Second World War. The original test consists of two parts, with part 1 presenting items with large black and white aerial views of a given location and requiring the test-taker to identify the location of specific features on this map, presented as small black and white aerial views. This test was of particular interest to us because it is basically a measure of the ability for perspective taking from a map-based aerial perspective. Aside from providing an interesting glimpse into history, the report generated by DuBois and his many colleagues made my student and I aware of a measure that was aptly named the “Spatial Orientations Test”.
