If you have watched YouTube videos of infants and toddlers with iPads, the impression is that the babies are using the mobile device.
But can that really be true?
To answer that question and others, a team of University of Iowa researchers set out to study more than 200 YouTube videos.
Their findings are published in the proceedings of the CHI 2015 conference, a prestigious meeting in the field of human-computer interaction.
In the paper, the university researchers write that their goal was to “provide a window into how these children are using tablets through an analysis of relevant YouTube videos.”
What they found was information that supports “opportunities for research and starting points for design.”
“By age two, 90 percent of the children in the videos had a moderate ability to use a tablet,” said Juan Pablo Hourcade, Ph.D., associate professor of computer science in the niversity of Iowa College of Liberal Arts and Sciences and lead author of the study.
“Just over 50 percent of 12-to-17-month-old children in the videos had a moderate ability.”
For the purposes of the study, Hourcade and his colleagues defined “moderate ability” as needing help from an adult to access apps, but being able to use them while displaying some difficulty with basic interactions.
The researchers believe their study is the first to study how infants and toddlers are actually using the devices.
Hourcade says he was inspired to use YouTube videos by another researcher who analyzed online videos of computer use by people with motor impairments.
He believes the YouTube clips enabled his group to conduct the research without having to ask infants and toddlers to use tablets, something that some pediatricians discourage.
“On the other hand, we know that infants and toddlers are using iPads and other devices because we’ve seen the videos recorded by their parents, and surveys confirm it is happening. It’s happened really quickly — before we could get out and arrange for more conventional studies,” he says.
Hourcade acknowledged the drawbacks of using unsolicited YouTube videos, such as not knowing the exact ages of the children pictured and that the children pictured were selected by their caregivers and may not be representative of the larger society.
However, he says the researchers were able to estimate the ages of the children (two-thirds of the videos included the age) and observe a clear progression of successful performance linked to age that is consistent with developmental milestones.
“One of the biggest differences we found is that when children turn one year old, they switch from using both hands and all their fingers to interact with the tablet to using an index finger — which is what adults do,” he says.
He says he hopes that the study and others that follow will influence the development of apps that encourage interactive education for infants and toddlers. The apps he envisions might be similar to the social and interactive-like children’s programs currently found on public television.
“We may be able to use research on what makes certain children’s educational television programs beneficial as a starting point and go on from there,” he says.
