Is the ‘Idiot's Box’ raising idiocy? Early and middle childhood television watching and child cognitive outcome

Screen time impairs the relationship between physical fitness and academic attainment in children

“…3,25 In contrast, other studies have found a positive relationship 26,27 or reported no association. 28 The present results showed that screen time was inversely associated with academic attainment in both genders (data not shown). Furthermore, a recent large study in English youths 13 and a two year longitudinal study 14 showed a negative association between screen time and CRF independent of PA.…”

Are Television and Video Games Really Harmful for Kids?

Chou, Rashad, and Grossman (2008) showed that early childhood exposure to fast-food restaurant advertisement on TV was associated with obesity.…”

Furthermore, because opposing TV or video games is very difficult for parents today, they may be more interested in the extent to which TV or video games are significantly harmful to children, rather than whether they are harmful.…”

Physical Activity, Sedentary Behavior, and Academic Performance in Finnish Children

“…However, Borzekowski and Robinson (1), and Jackson et al (14) reported a positive relationship between Internet/computer use and academic performance, and Munasib and Bhattacharya (24) reported no association between television viewing and academic achievement. Objectively measured sedentary time is a current topic of interest in physiology but has not been extensively studied from the psychological point of view.…”
