In a groundbreaking study spanning 23 years and involving over 30,000 children under the age of 12, experts emphasize the need for increased government support to assist parents in navigating their children’s tech usage. The extensive analysis of neuroimaging research over this period indicates that the time children spend on devices like TVs and computers can have lasting
effects on brain function. This research unveils a mix of both negative and positive impacts on young minds.
While researchers acknowledge these effects, they avoid recommending specific screen time limits, considering the potential for confrontation. Instead, they propose that policymakers should help parents manage digital engagement by supporting programs fostering positive brain development. Insights from Neuroimaging Studies Recently published in the peer-reviewed journal Early Education and Development, the evidence review delves into 33 studies utilizing neuroimaging technology to measure the impact of digital technology on the brains of children under 12. The study includes insights from over 30,000 participants.
The research indicates that screen time leads to changes in the pre-frontal cortex, affecting executive functions like working memory and adaptability. The impacts extend to the parietal lobe, crucial for processing touch, pressure, heat, cold, and pain, as well as the temporal lobe, essential for memory, hearing, and language. The occipital lobe, responsible for interpreting visual
information, is also affected.
Digital Experiences and Cognitive Development
The study’s corresponding author, Chair Professor Hui Li from The Education University of Hong Kong’s Faculty of Education and Human Development, emphasizes the influence of digital experiences on children’s cognitive development. While limiting screen time is effective, Professor Li suggests that more innovative, friendly, and practical strategies should be developed and
implemented.
Professor Li stresses the need for policymakers to craft evidence-based policies safeguarding and enhancing brain development in children amidst the digital era. This could involve providing resources and incentives for creating and evaluating digital interventions aimed at bolstering brain growth in children.
The study acknowledges limitations, such as the novelty of the topic and evolving research technologies. Future research recommendations include exploring longitudinal studies on the impact of screens on brain functions, addressing critical questions about early digital use versus cognitive processes, and examining the effects of different types of digital equipment and usage
modes.
