As children play with objects and watch adults using objects, they learn how the world works. Eventually children learn that objects are defined by their uses. Children also learn to think flexibly about possible object uses. We found that from 3 to 5 years children learn that every object has a function (that is, an abstract concept of ‘function’). They also get better at classifying objects by function, and labeling things based on how they work.
