The work of Lev Vygotsky has become the foundation of much research and theory in cognitive development over the past several decades, particularly of what has become known as Social Development Theory.

This theory suggests that social interaction leads to continuous step-by-step changes in children's thought and behavior that can vary greatly from culture to culture.

Vygotsky believes that young children are curious and actively involved in their own learning and the discovery and development of new understandings/schema.

According to Vygotsky , much important learning by the child occurs through social interaction with a skillful tutor. The tutor may model behaviors and/or provide verbal instructions for the child. Vygotsky refers to this as co-operative or collaborative dialogue. The child seeks to understand the actions or instructions provided by the tutor (often the parent or teacher) then internalizes the information, using it to guide or regulate their own performance.
