The statement "Vygotsky's theory of cognitive development best represents a stage theory of development" is false.
Vygotsky's theory of cognitive development states that the cognitive abilities of an individual are socially guided and constructed.
Therefore it can be concluded that Vygotsky is focused on the development of cognition as affected by the social interactions rather on the stages as in the case of Piaget's theory.
Therefore the statement is false.
