Key Theoretical Approaches
Nativist
Abilities are innate, present from birth
Thinkers: Descartes (1638), Kant (1781)
Empiricist
Knowledge comes from experience
John Locke (1690): “Tabula Rasa” (blank slate)
William James: Infants’ world is a “blooming buzzing confusion”
Constructivist
Knowledge is constructed through interaction with the world
Piaget: “Continuous creativity through experience”
Empirical Evidence
Infants are born with many perceptual abilities
Development is also shaped by interaction and experience
