If you want babies to learn faster, forget those "Baby Einstein" videos and defy their expectations a little. A new study has found that babies learn new things by leveraging the core information they are born with.
When something surprises a baby, like an object not behaving the way a baby expects it to, the baby not only focuses on that object, but ultimately learns more about it than from a similar yet predictable object.
The study upcoming in Science involved four experiments with pre-verbal 11-month-old babies, designed to determine whether babies learned more effectively about objects that defied their expectations. If they did, researchers wondered if babies would also seek out more information about surprising objects and if this exploration meant babies were trying to find explanations for the objects’ strange behavior.
First the researchers showed the babies both surprising and predictable situations regarding an object. For instance, one group of infants saw a ball roll down a ramp and appear to be stopped by a wall in its path. Another group saw the ball roll down the ramp and appear to pass — as if by magic — right through the wall. When the researchers gave the babies new information about the surprising ball, the babies learned significantly better. In fact, the infants showed no evidence of learning about the predictable ball. Furthermore, the researchers found that the babies chose to explore the ball that had defied their expectations, even more than toys that were brand new but had not done anything surprising.
The researchers found that the babies didn’t just learn more about surprising objects — they wanted to understand them. For instance, when the babies saw the surprising event in which the ball appeared to pass through the wall, they tested the ball’s solidity by banging it on the table. But when babies saw a different surprising event, in which the ball appeared to hover in midair, they tested the ball’s gravity by dropping it onto the floor.
These results suggest that babies were testing specific hypotheses about the objects’ surprising behavior.
“For young learners, the world is an incredibly complex place filled with dynamic stimuli. How do learners know what to focus on and learn more about, and what to ignore? Our research suggests that infants use what they already know about the world to form predictions. When these predictions are shown to be wrong, infants use this as a special opportunity for learning,” said Lisa Feigenson, a professor of psychology at Johns Hopkins University. “When babies are surprised, they learn much better, as though they are taking the occasion to try to figure something out about their world.”
“The infants’ behaviors are not merely reflexive responses to the novelty of surprising outcomes, but instead reflect deeper attempts to learn about aspects of the world that failed to accord with expectations,” said lead author and psychology doctoral student Aimee Stahl. “Infants are not only equipped with core knowledge about fundamental aspects of the world, but from early in their lives, they harness this knowledge to empower new learning.”
