Who created Social Interactionist Theory?

• A. Skinner
• B. Piaget
• C. Vygotsky
• D. Chomsky

Answer: (C)

Cognition grows through social interaction and language within a cultural setting. This view holds that learning happens through guided participation and collaboration with more knowledgeable others, with language serving as a tool that helps thinking and problem solving. A key idea is the Zone of Proximal Development, the range of tasks a learner can’t yet do alone but can accomplish with support, demonstration, and feedback; this scaffolding gradually becomes internalized, turning guided strategies into independent thought. Lev Vygotsky articulated this approach, contrasting with Skinner’s focus on reinforcement of observable behavior, Piaget’s emphasis on solitary exploration and developmental stages, and Chomsky’s view of an innate language structure.
