Internalization (John-Steiner's Extension)
The Vygotskian mechanism—external social patterns becoming internal cognitive capacity—extended by John-Steiner to adult creativity, where mentor's voice becomes practitioner's conscience and community norms become individual taste.
Internalization is the developmental process through which patterns first encountered in social interaction migrate to the internal plane and become individual cognitive capacity. Vygotsky demonstrated this in children: the child who solves puzzles with her mother's guidance eventually solves them alone, not by discarding the guidance but by absorbing it into her own cognitive architecture. John-Steiner extended the mechanism to adult creative development, showing that a physicist's internalized mentor—the voice that asks 'Have you checked the boundary conditions?'—is the residue of years of actual mentoring interactions, now operating as autonomous internal critique. The community's aesthetic standards become the individual's taste. The collaborator's way of approaching problems becomes the practitioner's invisible tool. Internalization is complete when the origin becomes invisible—when the borrowed pattern feels like native equipment.

John-Steiner's research revealed internalization operating across every creative life she studied. Apprentices internalized their masters' stances toward materials—the cabinetmaker's feel for wood grain, the surgeon's respect for tissue—through thousands of hours of observation and
