Study: Parents Should Limit All Screen Media for Pre-K Kids
A new study suggests that parents should delay introducing their young children to any screen media, and should limit preschoolers’ use of mobile devices, including smartphones and tablets.
The findings are published in the Journal of the American Medical Association Pediatrics.
For more than two-and-a-half-years, a research team from the University of California, Davis observed 56 children (ages 32 to 47 months) and surveyed their parents. The researchers assessed children’s self-regulation skills — those skills needed to plan, control, and monitor their thoughts, feelings, and behaviors.
Previous research has shown that young children’s self-regulation skills can predict later academic success, social functioning, physical and mental health, income and criminality.
The findings reveal that self-regulation skills were lower among children who began using any screen media devices (including television, computers, smartphones, and/or tablets) earlier in life, or who currently used mobile devices (smartphones and/or tablets) more often than others in the sample.
“Young children are often exposed to substantial amounts of screen media,” said the study’s primary author, Amanda C. Lawrence, a doctoral candidate in the Human Development Graduate Group at UC Davis.
“Even though consumption of moderate amounts of high-quality children’s media has been established to have a positive influence on development, the current findings support limiting children’s use of mobile devices.”
The researchers cited other reasons for cautious use of mobile devices by young children. “The portable nature of mobile devices allows them to be used in any location, such as while waiting for appointments, or in line at a grocery store. The screen use, then, could interfere with sensitive and responsive interactions with parents or practicing self-soothing behaviors that support optimal development,” said Lawrence.
For the study, children and their parents participated in 90-minute visits to an on-campus research laboratory, where the children were asked to complete 10 tasks to evaluate their ability to self-regulate. Tasks were as varied as walking a line slowly, taking turns with the researcher in building a tower out of blocks, and delaying gratification — for example, being asked to hold off unwrapping a gift while the researcher briefly left the room.
Parents reported their child’s screen use in a novel survey designed by Lawrence, and the researchers calculated the children’s reported age at first use of screen media and average time spent per week on each device.
The study results include the following:
- There was substantial variation in the amount of time children spent with screen media devices in the average week in this community sample. Screen time for traditional devices (television, computers) ranged from 0 to 68 hours per week, and 0 to 14 hours per week for mobile devices (tablets, smartphones).
- Children’s screen time in the average week was not linked to their family’s income in this sample, but children growing up in higher-income households started using mobile devices at a younger age than lower-income households.
- Screen time also did not differ by racial/ethnic minority status in this sample.
In addition, children’s exposure to traditional screen devices (televisions, computers) in the average week was not related to their self-regulation, in contrast to most previous studies.
Lawrence speculates that messaging about providing child-directed, educational content and cautioning parents to monitor children’s viewing has reached parents and has been effective, at least among some groups.
This is a small study, but the beginning of a long-term longitudinal study of children’s development of self-regulation and looking at all screen media devices over multiple years with more children and parents, researchers said.
Co-authors of the study are Dr. Daniel Ewon Choe, assistant professor of human development and family studies, and Madhuri S. Narayan, who was an undergraduate student when working on the research.
