Vygotsky's term for the process by which shared cultural ways of acting become the child's own:

1. Skills such as riding a bicycle or using a pencil begin outside the child, in society. 2. Through activity with others, the child masters them. 3. Vygotsky called this taking in of shared cultural knowledge **internalization**. 4. A further step, appropriation, is adapting such tools to personal use. **Why not the others:** Accommodation, equilibration and assimilation are Piaget's individual processes, not Vygotsky's social one. _Source: Wikipedia, "Lev Vygotsky", section "Cultural mediation and internalization" (revision 1377698493)_
