His subjects were traditional farmers and herders who had never attended school and could not read. Luria presented them with simple tasks: grouping objects (hammer, saw, hatchet, log), solving syllogisms ('All bears in the Far North are white; Novaya Zemlya is in the Far North; what color are the bears?'), and defining abstract concepts. The results were revelatory. Non-literate subjects refused to group objects categorically; they grouped situationally ('You need the log to work with the tools').
