Let's explore Renée Baillargeon and Infant Cognition

Baillargeon and Infant Physical Cognition

Renée Baillargeon (1954–) transformed developmental psychology by demonstrating that infants possess sophisticated knowledge of the physical world far earlier than Piaget's sensorimotor stage theory predicts. Using looking-time paradigms rather than reaching tasks, she documented surprise-like reactions in infants under 6 months — and eventually under 3 months — when objects violated basic physical principles.
