Final answer:
Lev Vygotsky emphasized the influence of social interaction and culture on cognitive development, contrasting with Piaget's focus on biological processes.
Step-by-step explanation:
Whereas Jean Piaget emphasized the biological processes of cognitive development, Lev Vygotsky emphasized the effects of A. Social interaction and culture on development. Vygotsky's sociocultural theory of development posits that human development is deeply enmeshed in and influenced by one's cultural background and the social interactions one experiences. He asserted that elements such as language and thought are shaped through engagement with others in a cultural context, and these interactions play a pivotal role in the formation of cognitive abilities. The development of moral understanding, as researched by Lawrence Kohlberg, further supports the cognitive aspect of human growth. While Piaget's theory of cognitive development stressed how children's thinking evolves through distinct stages, Vygotsky offered a complementary perspective by highlighting the continuous interaction between individuals and their social environments. His work affirms the significance of culture and social communication as fundamental components in shaping cognitive development.
