Is fantasy play a Western invention?

From a T. M. Lurhmann op-ed in the NYTimes:

What does it mean that our society places such a premium on fantasy and imagination? “No culture,” observes the child psychologist Suzanne Gaskins, “comes close to the level of resources for play provided by middle-class Euro-American parents.” In many traditional societies, children play by imitating adults. They pretend to cook, marry, plant, fish, hunt.

“Inventive pretend,” in which children pretend the fantastic or impossible (enchanted princesses, dragon hunters) “is rarely — if ever — observed in non-industrialized or traditional cultures,” Gaskins says. That may be because inventive play often requires adult involvement. Observing the lack of fantasy play among the Manus children in New Guinea, Margaret Mead noted that “the great majority of children will not even imagine bears under the bed unless the adult provides the bear.”

Westerners, by contrast, not only tolerate fantasy play but actively encourage it, for adults as well as for children. We are novel readers, movie watchers and game players.
