A-not-B effect [PIAGET'S THEORY] | tendency of infants to reach for a hidden object where it was previously hidden (place A), rather than where it was hidden most recently while the child watched (place B) |
assimilation [PIAGET'S THEORY] | developing child's process of interpreting the environment in terms of the schemas he already has |
accommodation [PIAGET'S THEORY] | developing child's process of changing his schemas based on his interactions with the environment |
preoperational period [PIAGET'S THEORY] | (age 2 to 7) child can think representationally, but can't yet relate these representations to each other or take a point of view other than her own |
