iPad kids are more anxious, less resilient, and slower decision makers

If you're thinking of plopping your infant in front of a screen to get some peace and quiet, you might want to reconsider - higher screen exposure in infancy was linked to longer decision times later on and higher anxiety symptoms in the teenage years.

A group of Singaporean researchers who studied a cohort of 168 children for more than a decade found that those exposed to screens in infancy (before two years of age) showed accelerated maturation of brain networks involved in visual processing and cognitive control. That faster specialization, the researchers suggest, was associated with slower decision-making in childhood, and in turn, higher anxiety symptoms in adolescence.

"During normal development, brain networks gradually become more specialised over time," according to the study's lead author Dr. Huang Pei. "However, in children with high screen exposure, the networks controlling vision and cognition specialised faster, before they had developed the ...
