Introduction
Recent research conducted by Drexel University sheds light on the potential impact of screen time on children under the age of 2. The study, published in JAMA Pediatrics, explores the association between television screen time and sensory differences in toddlerhood. Here are key findings and insights from the study:
Increased Likelihood of Sensory Differences
- Children who watched television or DVDs at 12 months were twice as likely to experience “atypical sensory processing” by 36 months compared to their peers.
- Each additional hour of screen exposure after 18 months was linked to a 20% increased likelihood of sensory processing differences.
Study Details
- The study involved analyzing 1,500 caregiver surveys on sensory preferences, focusing on sensitivity, preference, or avoidance of different stimuli.
- Data collection specifically looked at television viewing, excluding smartphones or tablets, as the survey data was gathered prior to 2014.
Sensory Processing Outcomes
- Sensory processing behaviors, such as “sensation seeking,” “sensation avoiding,” and “low registration,” were assessed using the Infant/Toddler Sensory Profile (ITSP) at 33 months.
- Greater TV exposure by the second birthday correlated with increased likelihood of atypical sensory processing behaviors.
Association with Developmental and Behavioral Issues
- The study adds to a growing body of evidence linking screen time in infants and toddlers to various developmental and behavioral outcomes, including language delay, autism spectrum disorder, and problem-solving delays.
American Academy of Pediatrics (AAP) Recommendations
- The AAP advises against screen time for children under 2, except for live video chats. For ages 2 to 5, a 1-hour daily screen time limit is recommended.
- Despite these recommendations, research shows that many young children surpass these limits.
Expert Perspectives
- Dr. Karen Heffler, lead author of the study, emphasizes the importance of understanding potential factors impacting children’s development, particularly for those under one year of age.
- Dr. Emily Myers highlights the need for a nuanced approach, considering individual differences and family environments.
Implications and Recommendations
- The study suggests a link between high screen time and developmental problems, urging consideration for screen time reduction in toddlers exhibiting sensory symptoms.
- Parent training and education are deemed crucial for minimizing screen time in children under two years.
Conclusion
As technology becomes increasingly pervasive, understanding the potential impact of screen time on young children’s sensory development is crucial. While the study establishes a correlation, further research is needed to delve into the mechanisms underlying the association between early-life screen time and atypical sensory processing. Parents are encouraged to be mindful of screen exposure, considering its potential influence on a child’s sensory experiences and overall well-being.
