Final answer:
Vygotsky's theory is not heavily based on Freudian principles. They differ significantly in terms of their focus and core principles.
Step-by-step explanation:
b) False
Vygotsky's theory is not heavily based upon Freudian theoretical principles. Although both Vygotsky and Freud were influential psychologists, their theories differ significantly in terms of their focus and core principles.
Vygotsky's sociocultural theory of development emphasizes the role of culture and social interaction in human development. According to Vygotsky, a child's social world and interactions with others shape their language, thought, and cognitive abilities. He also considers historical influences as important factors in development.
On the other hand, Freud's psychoanalytic theory focuses on unconscious processes, the impact of early childhood experiences, and the role of instincts and drives in shaping behavior.
