好奇驱使婴儿学习

Infants have innate¹ knowledge about the world and when their expectations are defied, they learn best, researchers at Johns Hopkins University found. In a paper to be published April 3 in the journal Science, cognitive² psychologists Aimee E. Stahl and Lisa Feigenson demonstrate for the first time that babies learn new things by leveraging³ 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.

 

"For young learners, the world is an incredibly complex place filled with dynamic stimuli⁴. 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 Feigenson, a professor of psychological and brain sciences in the university's Krieger School of Arts and Sciences. "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 two researchers' study involved four experiments with preverbal 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.
