Abstract
Excessive screen time during early childhood has been negatively associated with cognitive development, including poor academic success.1 Social integration2 and delayed gratification (ie patience), are key childhood factors that have been associated with positive achievements in later life.3 Despite this, little is known about the possible association between screen time and these childhood factors. This study fills a gap in our knowledge, by investigating the association between screen time; delayed gratification, which is waiting for a larger reward; and social integration, which is the number of times a child is called as a friend by their classmates.
