The social–ecological context of media use and school success

Abstract

Theseassociations may be due to the improved employment andfinancial opportunities that high academic achievementallows, but there are likely other explanatory variables--- such as family functioning, child intellectual or self-regulation abilities, stress associated with chronic poverty,or premorbid mental health conditions, which influenceboth academic achievement and later outcomes. Regard-less, identification of potentially modifiable contributors toschool achievement is worthwhile, as improving a child’sacademic trajectory has important life course relevance.A growing literature has examined physical activityas a predictor of school success, with good reason:laboratory-based studiessuggestthatboutsofhigh-intensityphysical activity can improve immediate cognitive func-tioning, such as impulse inhibition and working memory.
