A recent study indicates that screen time has a significant and lasting effect on the brains of young individuals. According to the study activities like watching TV, playing video games, and using tablets can have both positive and negative outcomes.
Excessive screen time reduces problem-solving ability in children
The research, which analyzed 33 neuroimaging studies conducted over 23 years, found that screen time can lead to changes in the pre-frontal cortex, which is responsible for functions like working memory and adapting to different situations.
According to research, children under 12 who use tablet devices may have diminished problem-solving abilities and poorer brain function. In addition, four separate studies have found that heavy internet use and video gaming can lead to adverse changes in brain regions that affect intelligence quotients and brain volume.
The research indicates that playing video games could potentially elevate cognitive demands, leading to potential improvements in children’s executive functions and cognitive abilities.
However, the researchers are not advocating for specific restrictions on screen time, but they are urging policymakers to support initiatives that promote positive brain development.
Hui Li, Chair Professor at The Education University of Hong Kong, emphasizes that children’s cognitive development can be influenced by their digital experiences. While limiting screen time is one effective approach, there is a need for more creative and practical strategies to be developed and implemented.
Screen time impacts various brain areas
According to the researchers there is need for policymakers to provide proper guidance and support for children’s digital engagement. The study indicates that screen time impacts key brain areas: the parietal lobe, temporal lobe, and occipital lobe. The research aims to uncover the effects of digital activity on brain plasticity during crucial developmental stages, emphasizing the importance of support, especially before age eight for visual development and up to age 12 for language learning.
Researchers conducted a literature review spanning January 2000 to April 2023, exploring the digital habits of children from six months old and their influence on brain development. Findings reveal screen-based media as the predominant digital activity among participants, highlighting its prevalence.
