|---|---|
| Where Baillargeon differed from Piaget | Infants in the sensorimotor stage as young as 3 months had a better understanding of the world than Piaget gave them credit for |
| Baillargeon’s explanation of infant abilities | Infants don’t search for hidden objects not because they don’t know object permanence but because of lack of motor skills & are easily distracted. They understand object permanence form the age of 3 months |
| Graber (1987): Violation of Expectations - procedure | 24 babies, 5-6 months, tall & short rabbit pass behind screen to show object permanence. Expected event with screen with window is tall rabbit is seen but not short. Unexpected event is neither can be seen |
| Graber (1987): Violation of Expectations - findings | Babies on average look for longer at expected event than unexpected. Researchers interpret this as surprised baby. Since they’re surprised this shows a concept of object permanence |
| Violation of expectation | Researchers present infants with situations which align with the expected mechanisms of physical objects (expected event) & then 1 which doesn’t (unexpected event) to gauge surprise at this event |
| Different types of violations of expectation (3 types) | Occlusion – When an object blocks another the first object still exists Containment – When an object enters a container it will still be in there Support – An object should fall when unsupported or on a flat surface |
| Infant physical reasoning system (PRS) | Baillargeon said humans have an innate understanding of the physical world. This is why infants pay more attention to unexpected events, to learn more details about the world and improve their PRS |
