How children categorize living things
'Name everything you can think of that is alive.' How would a child respond to this question? Would his or her list be full of relatives, animals from movies and books, or perhaps neighborhood pets?

The children's responses revealed clear convergences among distinct communities but also illuminated differences among them.
