Screen Time Studies Parents Should Know About (Guest Post by Meghan Owenz, PhD)

There was an enthusiastic response to one of my recent podcast episodes, “The Facts About Kids and Screen Time,” featuring psychologist Meghan Owenz, where we discussed some of Magda Gerber’s opinions — and mine — about screen time and how Meghan’s research confirms those opinions. Meghan received a lot of feedback from listeners eager to know more, so she offered to expound a bit by sharing an overview of the findings from a variety of screen time studies…

 Screen Time Studies Parents Should Know About
by Meghan Owenz, PhD

I understand that parents turn to screens for a variety of reasons, and I am not here to judge or shame. If parents choose to utilize screens, research shows that high-quality educational programming can be neutral or helpful. Aim to choose shows which are slow-paced with easy-to-follow narratives. Sesame Street and Mister Rogers are safe places to start for older preschoolers. There are some proven strategies for selecting appropriate shows.

As Janet explains in the podcast, Magda Gerber advised delaying screens until age 6 and closely monitoring thereafter. In the decades since she expressed those views, an abundance of research has been done on screens and young children. What does it show? Well, it largely confirms Magda’s caution in delaying screens. Here are some interesting studies that demonstrate the value in delaying screens during your child’s early life.

  • Can a DVD or Television Program Teach language?

To a baby? No. In one study, 72 infants between the ages of 12- to 18-months were randomly assigned to four conditions: watching the video (5x per week for 4 weeks) while interacting with their parents; watching the video (5x per week for 4 weeks) without interacting with their parents; giving parents  the list of target words the video attempted to teach and telling the parents to attempt to teach their babies the words in any way which seemed natural to them; and the control group;1 The researchers conducted pre- and post-tests of the target words by asking the baby to point to the correct object when they named a target word (two objects were presented).

This study is highly regarded because it was particularly well-designed. The infant participants viewed the videos at least 20 times. If there was any learning that could occur by viewing baby videos, it should have been readily apparent. However, the results indicate that only the infants in the parent-teaching group performed above chance. The researchers summarize this result saying, “Children who had extensive exposure to a popular infant video over a full month, either with a parent or alone, did not learn any more new words than did children with no exposure to the video at all.” Can language suffer from television or DVDs?

In a correlational study, researchers found that for every hour of baby media infants between 8 and 16-months viewed (per parent report), they knew 6 to 8 fewer words.2 While parent-reports may be less standardized than other measures, it is of particular interest given that parents who show their children baby media to do so in an attempt to help them. Survey studies find that parents tend to believe baby videos are improving their children’s vocabulary, so the fact that a significant difference in word knowledge was found via parent report is rather telling.

  • Attention and Screen Time

Longitudinal research demonstrated a link between television viewing at ages 1 and 3 and attentional problems at age 7.3 In that particular study, which included a nationally representative sample of 1,278 children, the average one-year-old watched an average of 2.2 hours of television, and the average three-year-old watched an average of 3.6 hour of television per week. Each hour of television viewed was associated with a 10% increase in the risk for attention problems when the child enters school.

  • Attention and Screen Time in the Lab

An experimental study demonstrated that after viewing just 9 minutes of a fast-paced “entertainment” children’s show, children performed worse on a task which required executive control.4 The children were four-year-olds, and the entertainment show was Sponge Bob Square Pants. Executive control is the ability to suppress impulses and maintain sustained attention, among other things. The children who viewed the “entertainment” show exhibited executive functioning impairment compared to children who viewed an “educational” program and those who completed a drawing task.

  • Sleep Problems

The association between children’s sleep and screen time is well-documented and clear.  A review of over 67 studies demonstrates that screen time is negatively associated with sleep outcomes.5 Screen time is associated with two problematic sleep outcomes: going to bed later, and sleeping less overall.

  • Obesity

The research on the link between sedentary screen time and extra weight gain is well-documented. A longitudinal study of more than 7,000 U.S. children found that the more TV children viewed, the more likely they were to gain excessive weight between Kindergarten and Grade 5.6 In a longitudinal study of 1,037 participants, TV viewing in childhood predicted excess weight into adulthood.7 Interestingly, in this study, television viewing during childhood was a stronger predictor of adult Body Mass Index (BMI) than adult television viewing. The researchers suggest that efforts to reduce adult obesity need to start with childhood screen time habits.

  • Aggression

More than 50 years of research involving over 300 studies demonstrates that watching TV violence makes kids more aggressive.8 The research on this is really quite good.  They haven’t just studied what children naturally watch. They have also done experimental studies and found that children who are not usually aggressive become aggressive. The American Academy of Pediatrics (AAP) made a point to highlight that the research base includes a variety of methodologies and large-scale meta-analyses. The take-home: There is a “proven scientific connection between virtual violence and real-world aggression.” The AAP appropriately defines “aggression” as an act in which the intent is to harm the other person, either emotionally or physically.

These findings are concerning when we consider the violence that is portrayed in children’s programming. The AAP policy statement highlights some disturbing (although not necessarily) shocking statistics about virtual violence. In an analysis done in the year 2000, all G-rated films contained violence, as did 60% of prime time television shows. Based on a study conducted in 1998 focused solely on television, it is estimated that the average child would view 8000 murders and 100,000 other acts of violence by middle school.

  • Babies and Toddlers Self-Soothing

Young children learn problem-solving and emotional regulation by experiencing and working through tough emotions. The presence of a screen during a melt-down could interrupt those learning processes. Correlational research suggests that use of screens to calm a child and social-emotional difficulties are significantly associated with one another.9 This research cannot tell us which came first: either parents of children with social-emotional difficulties may be more likely to turn to a screen to help with the behavior; or,  the use of the screen may encourage social-emotional difficulties by not allowing the child to learn to cope with emotions and develop the skills necessary for regulation.

  • Clifford the Big Red Dog

Researchers sought to determine how helpful a segment of Clifford the Big Red Dog could be on children’s understanding of the importance of a complex topic:  inclusion and acceptance of differences.10 The episode depicted a three-legged dog. The characters were initially fearful of the dog and excluded it. This went on for some time until the end of the segment when they learned the importance of being friends. However, the research suggested that the kids could come away from the show with the opposite message: to exclude and be fearful of differences. The authors note “the negative emotional content can over-ride other, more positive elements within a given episode,” making it more difficult for kids to understand the moral or take-home message that the episode is supposedly promoting.

  • Teaching Honesty

Some shows for young children attempt to teach children valuable social lessons, such as the importance of honesty. But your child will likely learn social lessons better from you.  One study found that children sometimes come away with the opposite “lesson,” thinking a solution is to lie as opposed to tell the truth. In the study, children were more like to remember the conflict or struggle over lying, but not the solution.11 Because children cannot consistently understand the difference between fantasy and reality until after age 6, the conflict may be more salient to them. It is like a threat and their brain directs more resources towards it, making it likely that they will remember that conflict.

  • Putting it All Together: A Meta-Analysis

Much older research from 1978 had previously found that when prosocial content is mixed with violence or conflict, children focused on the antisocial components like violence more than outcomes or messages associated with the violence.12 A meta-analysis of previous studies found that when children were shown prosocial content with violence or conflict, there was an association with negative behavioral outcomes.13 The take-home: When there is scary, threatening or violent conflict, that is what children pay attention to and remember, often at the expense of remembering the consequences or solutions.

Conclusion

Taken as a whole, it would appear best to delay screens as Magda Gerber suggests. Join us at Screen-Free Parenting for motivation to delay and limit screens, articles on raising tech-wise children, and inspiration for tons of screen-free fun.

    Our guidelines for screen time for my kids (nearly 3 and 1.5) are:
    *together: they never watch on their own, always with myself or their dad, and we typically talk through it, about what we are seeing
    *short: no more than about ten minutes a day, and we often skip days
    *real: we do our best to look at videos that depict real things happening in real time (not sped up videos with crazy music or cartoons, but things that expand on their real life interests, like how to make a door (actual request from my older child), or a song that we are learning)

    I know there are so many approaches to screen time, and many parents may choose to avoid it completely for as long as possible, exactly because they are informed of the research. My husband and I feel that including some screen time in this way keeps it from becoming an elusive, forbidden fruit, sets an example for how we can use technology well and in moderation, and mitigates the risks mentioned.

    • avatar Meghan Owenz says:

      Love those guidelines! I think they are great and slowly introducing your little one to the positives of screen-time.

    Here’s what we did; when our first child was born, we got rid of our television. Put it out on the street. We haven’t missed it at all, and our kids have never known any other way of living.
    At night time- they read, or we take turns reading to each other. Sometimes they’ll ask about a show their peers are watching, so we may rent it on the computer for the weekend- the only time they get a little screen time. If we need news we have the radio, computers, and all our online subscriptions.
    we have a peaceful home, we have smart well read kids, and we have no advertising showing our daughter how she ‘should’ look, or showing our son how boys ‘should’ behave.
    we have no cable bill!
    we have more time with each other, for better or worse, and our stress levels have been reduced. Give it a try for a few months, it’s the way humans lived for thousands of years, and it just feels right.

    • avatar Meghan Owenz says:

      I so agree Eric! I love that gender stereotypes and commercialism don’t have free access to my kids. That’s a huge bonus of being screen-free. And, you’re right, it just feels easier.

  3. avatar Kate Flynn says:

    When I trained in Montessori more than 25 years ago, we learned that the act of putting the pixels together in your mind to form the image actually moved your mind toward a sleep state and that this, also, was not conducive to learning.

  4. avatar Liv says:

    With a newborn, a three year old and my husband being away on business for a week plus all of us being sick, and no family around, I’m afraid (carefully selected) TV has been life saver.

  5. So love this article! I’ve been trying to gather information as I happen across and just feel so happy to see that you’ve saved so much work for me by sharing your gathered studies here!

    My husband and I also agree with Amy’s statement about forbidden fruit. To counter the negative effects regarding content, I also felt that there should be a list of ‘acceptable’ videos and have been asked a few times to share mine, so finally put it here.
    htps://whenthediaperleaks.wordpress.com/2016/11/13/films-for-children-ages-25/

    We still operate by the no media under age 2. With a cumulation of < 2 hours of video a week.

  6. avatar Caitlin says:

    I wrote a couple of papers on this in college after learning about limiting screen time while nannying. I’ve been given a hard time about it but would rather that than have it negatively impact my daughter. I do have a question though! Is phone screen exposure the same? We do not let her play games or watch anything on our phones but do Facetime family. She loves seeing them but I am wondering if we should stop or limit her seeing them on the screen.

  7. avatar Sapana V says:

    The article is very informative. Thanks for sharing the facts and details.

  8. avatar Taylor Hollar Me says:

    I really love this article, and love your Podcasts. They are very informative and helpful. Although I do not have kids of my own yet, I do plan on having kids in the future. Hopefully. I am a totally blind person, and I’m looking for advice on how to deal with kids as a totally blind person do you have any advice on that?

    • avatar janet says:

      Thank you so much, Taylor. I’m thrilled you find my podcasts helpful! Have you explored general resources for blind parents? That’s where I would begin. Then I would be happy to help you with any specific concerns you have regarding Magda Gerber’s approach. I also do telephone consultations if you are ever interested in that.

    I have to say I have been very guilty of letting my 14 month old watch tv because he is a very needy/clingy child and its the only way I can get dinner ready or do laundry when I’m home with him. My mom also got him in the habit of giving him my phone while I dress him after his bath or changing a dirty diaper because he was so squirmy and would cry so now we are in this habit of letting him watch a video on our phone while we are doing this, and I always feel mom guilt when I do this, and your research obviously proves why I feel this way. He does get a lot of time outside and most of the day we just have music on and we play with his toys, but when I need to do something I find myself using tv as a clutch. Even in the restaurants, the only way we can make it through dinner is if we let him watch a video on our iphone (I know what you’re thinking or else he cries and wants me to hold him. Have I created a monster? Is it too late to turn back? What do you suggest I do? Slowly wean or just take it away altogether? Thank you!! I’m so worried I’m rotting his little brain…

  10. avatar Audra says:

    I try to limit my two year olds exposure to tv as much as possible, but with a new baby and working from home with my own business it seems like the only way to get things done sometimes. I try to encourage independent play but it’s rarely successful as she naturally wants me to play with her. I hate having to feel like I’m choosing between work and the screen time it necessitates and organic playtime with no negative side effects. Sigh.

  11. avatar Elizabeth says:

    Hi Meghan and Janet,

    I am curious what your thoughts are regarding screen time involving still photos on screens. My daughter loves looking at baby photos of herself, and we have been doing this in prperation for the arrival of her new baby sister. It started as something we did a couple times a week, but her requests to see pictures of herself on my iPad have been escalating and have expanded to requests for pictures of baby animals as well as videos (we try to limit the animal videos to BBC documentary segments less than 5 min. Long).

    I’m worried she is losing interest in reading books ar bedtime with the nightly requests for photos.

    Thanks!

  12. I’m a professional writer, and I just wanted to say how impressed I am with the quality of the content on your website. I stumbled onto it from one of those contracting sites, and, as a humble amateur of parenting topics (I like Steiner), I’ve rarely seen such a combination of sophisticated content with clear exposition. Really a pleasure to find such a good read!
    Best,
    Andy
