Jean Piaget and Len Vygotsky developed their theories of cognitive development during a similar time period, and while Piaget's theory remains the most recognized theory in this field, it is clear that each theory has strengths and weaknesses.

In your initial post, compare and contrast the theories of Piaget and Vygotsky on cognitive development, the role of sociocultural influences, and the ability to account for typical and atypical development across developmental domains.
