Cultural Transmission Through Shared Intentionality
Cultural learning enables humans to transmit cognitive schemas across generations through shared intentionality—the uniquely human capacity for collaborative attention and mutual understanding of communicative intent.
This is an axiom because it identifies the fundamental mechanism distinguishing human cultural evolution from other forms of social learning. Shared intentionality—the ability to engage in joint attention and recognize others as intentional agents with whom one can share mental states—is the prerequisite for high-fidelity cultural transmission of abstract schemas.
Michael Tomasello's research demonstrates that shared intentionality appears uniquely (or at least distinctively) in human development, emerging around 9-12 months and enabling pedagogy, ostensive communication, and imitation of intent rather than mere behavior. Unlike other species that may have social learning, humans can transmit not just behaviors but the underlying schemas, goals, and reasons. This creates cumulative cultural evolution where each generation can build on transmitted knowledge. Archaeological and anthropological evidence shows that the rate of cultural change accelerated dramatically once modern shared intentionality evolved.
This axiom matters for the curriculum because it explains how education is possible—why explicit teaching can transmit complex abstract schemas that would be difficult or impossible to acquire through individual experience alone. It justifies pedagogical practices that leverage shared attention, explanation, and joint problem-solving. Understanding this mechanism helps educators design learning environments that properly engage shared intentionality to maximize schema transmission fidelity.
