Executive Functioning in preschoolers

NYT's magazine has an interesting article on the importance of executive functioning among preschoolers and how once this skill of waiting and organization is developed, it will lead to later academic success.

Come on, Abigail.”

“No, wait!” Abigail said. “I’m not finished!” She was bent low over her clipboard, a stubby pencil in her hand, slowly scratching out the letters in the book’s title, one by one: T H E. . . .

“Abigail, we’re waiting!” Jocelyn said, staring forcefully at her classmate. Henry, sitting next to her, sighed dramatically.

“I’m going as fast as I can!” Abigail said, looking harried. She brushed a strand of hair out of her eyes and plowed ahead: V E R Y. . . .

The three children were seated at their classroom’s listening center, where their assignment was to leaf through a book together while listening on headphones to a CD with the voice of a teacher reading it aloud. The book in question was lying on the table in front of Jocelyn, and every few seconds, Abigail would jump up and lean over Jocelyn to peer at the cover, checking what came next in the title. Then she would dive back to the paper on her clipboard, and her pencil would carefully shape yet another letter: H U N. . . .

Henry fiddled with the CD player. Like Abigail and Jocelyn, he was a kindergarten student in Red Bank, a small town near the New Jersey shore. The students at the elementary school came mostly from working-class and low-income families, and, like the town itself, the student population was increasingly Hispanic. Jocelyn, with flowing dark hair, was the child of immigrants from Mexico; Henry was Hispanic with a spiky haircut; Abigail was white and blond.

“Abby!” Henry said. “Come on!” He and Jocelyn had long ago finished writing the title of the book on their lesson plans. They already had their headphones on. The only thing standing between them and the story was the pencil clutched in their classmate’s hand.

G R Y. . . .

“O.K., we’re starting,” Jocelyn announced. But they didn’t start. For all their impatience, they knew the rule of the listening center: You don’t start listening to the story until everyone is ready.

“Oh, man,” Henry said. He grabbed his face and lowered his head to the desk with a clunk.

C A T E R. . . .

“Let’s begin!” Jocelyn said.

“I’m almost done!” Abigail was hopping up and down now. “Don’t press it!” She bounced from foot to foot, still writing: P I L. . . .

“I’m pressing it!” Henry said. His finger hovered over the play button on the CD player . . . but it did not fall, not until Abigail etched out her last few letters and put on her headphones. Only then, finally, could the three of them turn the pages together and listen to “The Very Hungry Caterpillar.”

When the CD finished, each child took a piece of paper and drew three pictures to illustrate what happened at the beginning, in the middle and at the end of the book. Then they captioned each one, first drawing a series of horizontal lines under the pictures, one for each word, and then writing out each word, or an approximation thereof: For “butterfly,” Abigail wrote “btrfli.” Their language skills were pretty impressive for kindergarten students. But for the teachers and child psychologists running the program in which they were enrolled, those skills were considered secondary — not irrelevant, but not as important as the skills the children displayed before the story started, when all three were wrestling with themselves, fighting to overcome their impulses — in Abby’s case, the temptation to give up on writing out the whole title and just submit to the pleas of her friends; for Jocelyn and Henry, the urge to rip the pencil out of Abby’s hand and start the CD already.

Over the last few years, a new buzz phrase has emerged among scholars and scientists who study early-childhood development, a phrase that sounds more as if it belongs in the boardroom than the classroom: executive function. Originally a neuroscience term, it refers to the ability to think straight: to order your thoughts, to process information in a coherent way, to hold relevant details in your short-term memory, to avoid distractions and mental traps and focus on the task in front of you. And recently, cognitive psychologists have come to believe that executive function, and specifically the skill of self-regulation, might hold the answers to some of the most vexing questions in education today.

The ability of young children to control their emotional and cognitive impulses, it turns out, is a remarkably strong indicator of both short-term and long-term success, academic and otherwise. In some studies, self-regulation skills have been shown to predict academic achievement more reliably than I.Q. tests. The problem is that just as we’re coming to understand the importance of self-regulation skills, those skills appear to be in short supply among young American children. In one recent national survey, 46 percent of kindergarten teachers said that at least half the kids in their classes had problems following directions. In another study, Head Start teachers reported that more than a quarter of their students exhibited serious self-control-related negative behaviors, like kicking or threatening other students, at least once a week. Walter Gilliam, a professor at Yale’s child-study center, estimates that each year, across the country, more than 5,000 children are expelled from pre-K programs because teachers feel unable to control them.

There is a popular belief that executive-function skills are fixed early on, a function of genes and parenting, and that other than medication, there’s not much that teachers and professionals can do to affect children’s impulsive behavior. In fact, though, there is growing evidence that the opposite is true, that executive-function skills are relatively malleable — quite possibly more malleable than I.Q., which is notoriously hard to increase over a sustained period. In laboratory studies, research psychologists have found that with executive function, practice helps; when children or adults repeatedly perform basic exercises in cognitive self-regulation, they get better at it. But when researchers try to take those experiments out of the lab and into the classroom, their success rate is much lower. Angela Duckworth, a psychologist at the University of Pennsylvania, has spent the last seven years trying to find reliable, repeatable methods to improve self-control in children. When I spoke to her recently, she told me about a six-week-long experiment that she and some colleagues conducted in 2003 with 40 fifth-grade students at a school in Philadelphia.

“We did everything right,” she told me: led the kids through self-control exercises, helped them reorganize their lockers, gave them rewards for completing their homework. And at the end of the experiment, the students dutifully reported that they now had more self-control than when they started the program. But in fact, they did not: the children who had been through the intervention did no better on a variety of measures than a control group at the same school. “We looked at teacher ratings of self-control, we looked at homework completion, we looked at standardized achievement tests, we looked at G.P.A., we looked at whether they were late to class more,” Duckworth explained. “We got zero effect on everything.” Despite that failure, Duckworth says she is convinced that it is possible to boost executive function among children — she just thinks it will require a more complex and thoroughgoing program than the one that she and her colleagues employed. “It’s not impossible,” she concludes, “but it’s damn hard.”
