Numerous cross-sectional and longitudinal studies have reported the detrimental effects of television viewing on children

Psychological research shows that watching TV affects children's language skills and other physical, cognitive and emotional development

Hikaru Takeuchi et al.

The study examined the lateral association between TV viewing time and regional grey matter/white matter volume (rGMV/rWMV) in 133 boys and 143 girls, as well as the longitudinal change in TV viewing duration over several years in 111 boys and 105 girls correlation between

After adjusting for confounding factors, television viewing had a positive effect on rGMV in parietal and medial prefrontal regions, and in cross-sectional analysis, television viewing had a positive effect on rGMV/rWMV in visual cortex regions

Anatomical Correlations of TV Watching Time (h) in Longitudinal Analysis

Longitudinal analysis revealed a positive effect of television viewing on rGMV in the hypothalamus/septa pellucidum and sensorimotor areas

Cross-sectional and longitudinal analyses also confirmed the negative impact of television viewing on verbal intelligence quotient (IQ)

Correlation between TV viewing time and IQ and how it changes over time

These anatomical associations may relate to previously known effects of television viewing on language ability, aggression, and physical activity

In conclusion, television viewing is directly or indirectly associated with children's neurocognitive development
