New UC Davis research suggests parents should limit screen media for preschoolers

 

 

 

 

 

 

 

Devices also limit interaction time

Researchers voiced 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.

The research team recruited participants by handing out flyers at preschools and community events. Data were collected between July 1, 2016, and Jan. 11, 2019. During individual 90-minute visits to an on-campus research laboratory, 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 were asked about screen use using a novel survey designed by Lawrence, and researchers calculated the children’s reported age at first use of screen media and average time spent per week on each device.

Other findings include:

  • 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 related 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.

Additionally, children’s exposure to what the researchers consider traditional screen devices (televisions, computers) in the average week was not related to their self-regulation, in contrast to most previous research. 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.

Algo exagerado pero disminuir la exposición electromagnética puede ser útil en algún grado … en especial para los chicos …

By Dr. Mercola

Most people today live in a sea of radiofrequencies (RF), emitted from wireless technologies of all kinds, from routers to smartphones, tablets, baby monitors, TVs, appliances, smart meters and more. In the featured ABC program “Wi-Fried,” originally aired in 2016, Maryanne Demasi, Ph.D., investigates the alleged safety of mobile devices.
