A story on National Public Radio on Feb. 22 discussed the evolution of play in the 20th century, and how that has impacted the cognitive development of children.

Excerpt:

Chudacoff's recently published history of child's play argues that for most of human history what children did when they played was roam in packs large or small, more or less unsupervised, and engage in freewheeling imaginative play. They were pirates and princesses, aristocrats and action heroes. Basically, says Chudacoff, they spent most of their time doing what looked like nothing much at all.

"They improvised play, whether it was in the outdoors… or whether it was on a street corner or somebody's back yard," Chudacoff says. "They improvised their own play; they regulated their play; they made up their own rules."

But during the second half of the 20th century, Chudacoff argues, play changed radically. Instead of spending their time in autonomous shifting make-believe, children were supplied with ever more specific toys for play and predetermined scripts. Essentially, instead of playing pirate with a tree branch they played Star Wars with a toy light saber. Chudacoff calls this the commercialization and co-optation of child's play — a trend which begins to shrink the size of children's imaginative space.
