Concept:Jean Piaget and Lev Vygotsky both studied children’s cognitive development but differed in their core focus: Piaget stressed the child’s own independent exploration, whereas Vygotsky highlighted the role of social and cultural interactions.
Explanation:Piaget believed children actively build understanding by using their senses and motor skills to explore the world on their own. He saw cognitive growth as a step-by-step process driven by the child's personal efforts.
Vygotsky argued that learning and thinking are shaped by the culture and society a child lives in. He viewed cognitive development as a socially mediated process, where guidance from adults and peers is essential.
Option A correctly captures this contrast: Piaget emphasized independent efforts; Vygotsky emphasized social mediation.
Options B, C, and D are wrong. Option B misstates Vygotsky’s view (he did not see children as passive). Option C reverses the emphasis – Vygotsky stressed language, Piaget stressed biological maturation. Option D also reverses their ideas about private speech: Piaget called it egocentric, while Vygotsky saw it as a tool for self-guidance.
Answer:Option A is correct.
