Luria's work was part of the Soviet cultural-historical psychology program, grounded in the thesis that higher mental functions are socially and technologically mediated. Vygotsky had argued that cognitive tools (language, writing, number systems) restructure thought; Luria set out to test the claim empirically. The Uzbek studies were conducted during a period of rapid Soviet-imposed modernization—collectivization, literacy campaigns, ideological education. Luria could compare adults who had grown up in traditional oral villages with adults of similar age who had received even minimal literacy training. The differences were stark and replicable.
The studies were suppressed during Stalin's era (Luria's findings were ideologically inconvenient) and not published in English until 1976, as Cognitive Development: Its Cultural and Social Foundations. By then, Ong had already encountered Luria's work through the scholarly networks connecting cognitive anthropology and communication theory. The findings became central to Ong's argument in Orality and Literacy—providing the empirical anchor for claims about how media shape minds. The hammer-saw-hatchet-log grouping task became one of the most cited examples in the literature on literacy and cognition.
The Ong volume uses Luria's test as a diagnostic instrument for the AI moment. Just as non-literate subjects could not 'see' categorical abstraction (the capability literacy produces), AI-mediated minds may be developing characteristic capabilities while losing others—and the loss may be as invisible to them as categorical thinking was invisible to Luria's Uzbek farmers. The test demonstrates that intelligent people, shaped by different media, literally cannot see the same things when they look at the same objects. The implications for cross-medium evaluation are profound: the AI-augmented builder and the pre-AI craftsman are not merely disagreeing about value; they are inhabiting different cognitive worlds.
Luria conducted the fieldwork in 1931–32 as part of a Soviet Academy of Sciences expedition studying the psychological effects of collectivization and literacy. He worked with interpreters in Uzbek and Kyrgyz villages, testing adults in settings as close to their daily lives as possible. The suppression lasted decades; the work was known in the Soviet Union but not widely available in the West until the 1970s. Ong encountered it through the network of scholars studying cognition and literacy—Eric Havelock, Jack Goody, David Olson—and recognized its importance immediately. The studies provided the empirical proof that cognition is medium-dependent, not merely culturally variable.
Situational versus categorical reasoning. Non-literate subjects group objects by use-context ('the log goes with the tools'); literate subjects group by abstract category ('these are all tools').
Rejection of formal syllogisms. Non-literate subjects refuse to reason from premises divorced from experience; they demand sensory evidence over logical inference.
Medium, not intelligence. The differences Luria documented are not differences in cognitive capacity but differences in the kind of thinking each medium enables and rewards.
Mutual invisibility. Each form of reasoning is opaque to the other; the categorical mind cannot see situational logic as valid, and the situational mind cannot see categorical abstraction as real.
