Ongoing Screen Time Series
A study in Ohio explores how screen time affects children’s brains. Researchers at Cincinnati Children's Hospital are examining the brains of 395 kids, starting their analysis with brain scans as early as birth. One participant, Rose Crimer, a five-year-old, participates in the Early Prediction Study which began in 2019. She is scanned while enjoying a movie, allowing researchers to compare current images to those taken when she was just days old.
The study, led by Dr. Nal Peri, looks at how various risk factors, including screen exposure, influence brain development. Research indicates that higher screen time may weaken parts of the brain involved in reading, language, and decision-making. This understanding raises important questions for parents about their children's screen habits.
Experts suggest that children should not be exposed to any screen time before the age of three. They highlight that society restricts access to many substances and activities, yet screens are often introduced without similar caution. Many compare excessive screen time to the dangers of tobacco, and researchers believe using devices around children can be similar to secondhand smoke.
For parents concerned about previous screen exposure, it’s crucial to model healthier behaviors. Parents are encouraged to minimize their own screen use to promote better interaction with their children. Shared activities, like reading and playing, are essential for language development and emotional growth. Engaging personally, rather than relying on screens, creates a supportive learning environment.
As screen use becomes prevalent in schools, parents can advocate for reduced screen time in classrooms. Questions about screen usage during lessons and the necessity of devices like iPads in early education can help guide important discussions with educators. Balancing educational needs with the effects of screen exposure remains a significant challenge for families and schools.

Correlation Between Screen Time and Development
Research indicates a link between increased screen time and weaker development in areas of the brain responsible for reading, language, and decision-making. Experts recommend that parents delay introducing screen time until after the age of three. They stress the importance of modeling healthy screen habits and encouraging interactive activities, such as playing and reading, to foster emotional and language development in children.
Family Participation
Rose Crimer's MRI Procedure
At Cincinnati Children's Hospital, Rose Crimer, a five-year-old participating in a significant study, pretended to be the captain of a submarine during her MRI. This procedure is part of a research study that started in 2019, involving 395 children. For 45 minutes, she enjoyed a movie while the MRI machine took detailed images of her brain. The use of goggles and headphones helped keep her calm as researchers collected scans to compare with images taken when she was just a few days old.
The Crimer Family's Perspective
Emily and Harry Crimer, Rose's parents, enrolled her in the study to better understand the effects of screen time. They noted the difference between today's devices, like smartphones and tablets, and what they experienced as children. They expressed concerns about how much more engaging these devices are, making it easy for kids to zone out. Experts in the field emphasize the importance of limiting screen time, especially for children under three, and offer guidance for parents to monitor and adjust screen usage effectively.
Screen Time's Impact
Findings from Dr. John Hutton's Research
Dr. John Hutton is leading research on how screen time affects children. His studies show that increased screen time can lead to weaker development in areas of the brain related to reading, language, and decision-making. The research involves tracking the brain development of many children over time. This helps to understand the risks associated with screen exposure.
Impact on Reading, Language, and Decision-Making
Experts advise limiting screen time for children, especially before the age of three. They emphasize the importance of engaging activities such as reading and playing with toys. These interactions promote better language and emotional development. Parents are also encouraged to model good behavior by reducing their own screen time and focusing on shared experiences with their children.

Guidance for Parents
Begin Screen Time After Age Three
Experts recommend that parents should not introduce screens to children before the age of three. Just as society restricts access to substances or activities like alcohol and voting, screen time should also have limits. The aim is to protect young children from the potentially negative effects of early exposure to screens.
Parental Influence and Role Modeling
Parents play a critical role in shaping their children's behaviors. If they wish to reduce their children's screen time, they must model less screen use themselves. When children see their parents engaged in activities that don’t involve screens, they are more likely to engage in similar behavior. Taking time to interact and talk with children is important for their emotional development.
