3. How do the child development theories of Arnold Gesell and Lev Vygotsky differ?

Gesell believed that we develop in an orderly sequence set by heredity or nature. Vygotsky believed the environment in which you grow (nuture) is more influential than nature.

Explanation:

Gesell observed and documented patterns in the way children develop, showing that all children go through similar and predictable sequences, though each child moves through these sequences at his or her own rate or pace.

Vygotsky was a seminal Russian psychologist who is best known for his sociocultural theory. He believed that social interaction plays a critical role in children's learning. Through such social interactions, children go through a continuous process of learning.
