Final Answer:
Lev Vygotsky's theory that emphasizes the relationship of the social environment, particularly cultural, to cognition and learning is C) Sociocultural Theory.
Step-by-step explanation:
Sociocultural Theory, developed by Lev Vygotsky, posits that cognitive development is deeply intertwined with the social and cultural context in which an individual exists. This theory underscores the idea that learning and cognitive processes are shaped by social interactions, cultural norms, and shared experiences.
Vygotsky introduced the concept of the Zone of Proximal Development (ZPD) as a key element within Sociocultural Theory. The ZPD is the range of tasks that a learner can perform with the help of a more knowledgeable person, such as a teacher or peer, but cannot yet do independently. This concept highlights the significance of social interactions in facilitating learning beyond individual capabilities.
In contrast, Social Cognitive Theory, while related to the broader field of social learning, is not specifically associated with Lev Vygotsky. The Behavioral Theory, on the other hand, focuses on observable behaviors and their reinforcement, neglecting the sociocultural context emphasized in Vygotsky's work.
In summary, Lev Vygotsky's theory that underscores the impact of the social environment, especially cultural factors, on cognition and learning is referred to as Sociocultural Theory, making option C the correct answer.
