"Can you think of a more complicated question to ask?" says Deb Roy, as he explains the genesis of his work.

In 2005, the artificial intelligence researcher at the Massachusetts Institute of Technology (MIT) Media Lab set out to understand how children learn to talk.

"We wanted to understand how minds work and how they develop and how the interplay of innate and environmental influence makes us who we are and how we learn to communicate." It was a big task and after years of research, scientists around the world had only begun to scratch the surface of it. But now, Professor Roy is beginning to get some answers, thanks to an unconventional approach, an accommodating family and a house wired with technology.

And the research may even have kick-backs for everything from robotics to video analysis.

SARAH WILSON was speaking proudly the other day when she declared: “My house is a little messy.”

Ms. Wilson has embraced a growing movement to restore the sometimes-untidy business of play to the lives of children. Her interest was piqued when she toured her local elementary school last year, a few months before Benjamin was to enroll in kindergarten. She still remembered her own kindergarten classroom from 1985: it had a sandbox, blocks and toys. But this one had a wall of computers and little desks.

“There’s no imaginative play anymore, no pretend,” Ms. Wilson said with a sigh.

For several years, studies and statistics have been mounting that suggest the culture of play in the United States is vanishing. Children spend far too much time in front of a screen, educators and parents lament — 7 hours 38 minutes a day on average, according to a survey by the Kaiser Family Foundation last year. And only one in five children live within walking distance (a half-mile) of a park or playground, according to a 2010 report by the federal Centers for Disease Control, making them even less inclined to frolic outdoors.
