Kids And Screen Time: What Does The Research Say? ( from NPR )

Kids are spending more time than ever in front of screens, and it may be inhibiting their ability to recognize emotions, according tonew research out of the University of California, Los Angeles.
The study, published in the journal Computers in Human Behavior, found that sixth-graders who went five days without exposure to technology were significantly better at reading human emotions than kids who had regular access to phones, televisions and computers.
The UCLA researchers studied two groups of sixth-graders from a Southern California public school. One group was sent to the Pali Institute, an outdoor education camp in Running Springs, Calif., where the kids had no access to electronic devices. For the other group, it was life as usual.
At the beginning and end of the five-day study period, both groups of kids were shown images of nearly 50 faces and asked to identify the feelings being modeled. Researchers found that the students who went to camp scored significantly higher when it came to reading facial emotions or other nonverbal cues than the students who continued to have access to their media devices.
"We were pleased to get an effect after five days," says Patricia Greenfield, a senior author of the study and a distinguished professor of psychology at UCLA. "We found that the kids who had been to camp without any screens but with lots of those opportunities and necessities for interacting with other people in person improved significantly more."
If the study were to be expanded, Greenfield says, she'd like to test the students at camp a third time — when they've been back at home with smartphones and tablets in their hands for five days.
"It might mean they would lose those skills if they weren't maintaining continual face-to-face interaction," she says.
A Wake-Up Call For Educators
There's a big takeaway for schools, Greenfield says.
"A lot of school systems are rushing to put iPads into the hands of students individually, and I don't think they've thought about the [social] cost," she explains. "This study should be, and we want it to be, a wake-up call to schools. They have to make sure their students are getting enough face-to-face social interaction. That might mean reducing screen time."
The results of the UCLA study seem to line up with prior research, says Marjorie Hogan, a pediatrician at Hennepin County Medical Center in Minneapolis and a spokeswoman for the American Academy of Pediatrics (AAP).
"Common sense tells me that if a child's laying on his or her bed and texting friends instead of getting together and saying, 'Hey, what's up,' that there's a problem there," she says. "I want people interacting ... on a common-sense level, and an experiential level. It does concern [me]."
Hogan relates the UCLA study's findings back to research on infants.
"When babies are babies, they're learning about human interaction with face-to-face time and with speaking to parents and having things they say modeled back to them," she says. "That need doesn't go away."
How Much Screen Time Is Too Much?
For decades the AAP has warned that children need to cut back on their screen time. The group's latest prescription: Entertainment "screen time" should be limited to two hours a day for children ages 3-18. And, for 2-year-olds and younger, none at all.
The sixth-graders who made up the sample in the UCLA study self-reported that they spent an average of more than four hours on a typical school day texting, watching television and playing video games.
The San Francisco nonprofit Common Sense Media studies screen time from birth and, in 2013, found that children under 8 (a younger sample than the kids in the UCLA study) were spending roughly two hours a day in front of a screen.
"If used appropriately, it's wonderful," Hogan says of digital media. "We don't want to demonize media, because it's going to be a part of everybody's lives increasingly, and we have to teach children how to make good choices around it, how to limit it and how to make sure it's not going to take the place of all the other good stuff out there."
Some research suggests that screen time can have lots of negative effects on kids, ranging from childhood obesity and irregular sleep patterns to social and/or behavioral
