Cognition in infancy Focus: Piaget and the knowledge of the physical world Focus on earliest stage: Infants first understanding of objects and object mechanics Focus on some specific developmental methods… since we don’t have access to a baby translator , how can we measure what very young infants might know?

Key idea: “The object concept” Object Permanence Objects continue to exist, even when unobserved Retention of physical properties Objects retain their solidity, texture, size etc. Retention of spatial properties
