It confirms many parents instinct regarding television. A study of sixty 4 year olds were randomly assigned to watch a fast paced television cartoon or an educational cartoon. The study found that children who watched the fast pace television cartoon performed significantly worse in executive function tasks.
The conclusion the researchers drew –‘just 9 minutes of viewing a fast-paced television cartoon had immediate negative effects on 4-year-olds’ executive function. Parents should be aware that fast-paced television shows could at least temporarily impair young children’s executive function.’
