Dr. Linda Pagani, the head of the research team, said: 'We found every additional hour of TV exposure among toddlers corresponded to a future decrease in classroom engagement and success at math, increased victimization by classmates, a more sedentary lifestyle, higher consumption of junk food and, ultimately, higher body mass index ...... Between the ages of two and four, even incremental exposure to television delayed development'.
Since TV exposure encourages a sedentary lifestyle, Dr. Pagani says, television viewing must be curbed for toddlers to avoid the maintenance of passive mental and physical habits in later childhood: 'Common sense would have it that TV exposure replaces time that could be spent engaging in other developmentally enriching activities and tasks which foster cognitive, behavioral, and motor development'.
