The document compares the theories of Piaget and Vygotsky on cognitive development. Piaget focused more on universal stages of individual cognitive development, while Vygotsky emphasized the social and cultural factors, as well as the important role of language in cognitive development. Vygotsky also discussed the concept of the "Zone of Proximal Development" which refers to what a child can do or learn with assistance from others.
