Who believes children encounter a series of developmental stages as they mature?

• A. Jean Piaget
• B. Jerome Bruner
• C. Lev Vygotsky
• D. B.F. Skinner

Answer: (B)

The idea being tested is that child development unfolds through distinct, qualitative stages as children mature. Jean Piaget is the theorist most closely associated with this view. He proposed four major stages of cognitive development—sensorimotor, preoperational, concrete operational, and formal operational—each representing a different way of thinking and internalizing the world. In the sensorimotor stage, infants learn through direct sensory and motor interaction and develop object permanence. In the preoperational stage, children become more symbolic but still struggle with understanding other perspectives (egocentrism) and conservation tasks. The concrete operational stage brings logical thinking about concrete objects and events, while the formal operational stage introduces abstract and hypothetical reasoning. Jerome Bruner, while influential in cognitive development and education, does not advocate a fixed series of maturation stages. His work emphasizes how learners construct knowledge through active discovery and introduces ideas like modes of representation (enactive, iconic, symbolic) and a spiral curriculum, where content is revisited at increasing levels of complexity. Lev Vygotsky focuses on social interaction and cultural tools shaping learning through the zone of proximal development, and B. F. Skinner centers on observable behavior and conditioning rather than internal stage progression.
