Xavier loves to write poetry. often he uses techniques that his favorite poets use, but typically he modifies these techniques to better suit his own style. this situation illustrates which of the concepts in vygotsky’s theory?

Socio-cultural theory of cognitive development.

Explanation: The Russian psychologist Vygotsky's theory is a milestone and the basis of  constructivism. He felt that social learning precedes development. He explains that "every function in child's cultural development occurs twice, firstly, on social level(interpsychological) and secondly, on individual level"(intrapsychological).

He says cognition and consciousness are the by-products of socialization.
